Parade Tag

Are you looking to get some exercise, connect a little with some people who aren’t in your house without resorting to Zoom, and do it all while safely following prevention measures? Here is a game for you to consider: Parade Tag!

Parade Tag Instructions

  1. Get a committed participants list in walking distance of one another.
  2. Pick a parade theme that you can dress up for while masked, and be sure it is one that the participants will be able to afford to engage with. Depending on the culture in your area, it may be best to decide this before working on Step 1.
  3. Pick an order of households to create your parade loop and make sure everyone knows what the order is so they know where they are going.
  4. Schedule a parade day that works for everyone. Depending on the culture in your area, it may be best to pick the schedule first before working on Step 1.
  5. Plan your household’s costumes.
  6. The first group goes to the next house and waves through the windows. Dancing and silliness are recommended but not required. After they’ve retreated a safe distance on their way back home, the second group leaves and goes to the third house. And so on, until the last group goes to the first house.

Considerations

If you have people who want to participate but cannot leave their homes, place them in the loop anyway. The people right before them on the list can wave through the windows to them, then continue on to the next house.

Make sure everyone is in agreement ahead of time about what a “safe distance away before the next group leaves their house” is. You can also mark these distances on the ground with chalk ahead of time if sidewalk chalk is permitted in your area.

How to Fact-Check Science

From deciding which soap to use or which light bulb to buy to discerning which politician is telling the truth about things like climate change or the proper approach to Covid-19 concerns, science is a big part of our daily lives. Most people, though, aren’t scientists. Chances are, you don’t have the time or money to just go out and get yourself a degree in a science field.

How do people go about fact checking scientific information when most people don’t have a background in science? In my experience as a scientist, frankly, most people do it rather badly. The worst part is how many people don’t realize that they are doing it badly and consequently both draw horribly incorrect conclusions and profess their false ideas to others, spreading misinformation.

And yet, as a tutor, I also recognize that people are genuinely doing the best they can with the information available to them. It is very easy to draw the wrong conclusion when the information one has is incorrect or insufficient. My intention with this piece is to provide information and context to support the non-scientist reader in spotting bad science, incorrect science reporting, and the outright lies so many politicians are fond of spouting.

Comic from XKCD; permalink: https://xkcd.com/1217/
Description: A scientist in a lab coat stands on a chair, aiming a handgun down at a Petri dish on a lab bench near a microscope. Text reads, “When you see a claim that a common drug or vitamin “kills cancer cells in a Petri dish,” Keep in mind: So does a handgun.”

Part 1: The Scientific Method and Experiment Design

“Science” refers to a method for discerning truth, to a body of knowledge collected by generations of scientists, and in many ways, to a culture. The scientific method is the process by which scientists determine which facts are true.

The general steps of the scientific method are as follows:

  1. Propose a question.
  2. Do background reading about relevant known information.
  3. Form an hypothesis (an informed guess as to the answer of the question).
  4. Create an experiment to test the hypothesis.
  5. Run the experiment.
  6. Collect data.
  7. Analyze the data.
  8. Form a conclusion about the hypothesis, or go back to step 4 and repeat the process as needed to have enough information to form a conclusion.
  9. Communicate the conclusion.

If you are new to the scientific method, check out this site for more details in an interactive format. It’s designed for kids doing science fair experiments, which makes it easier to read regardless of your age. In fact, science materials designed for kids are great for all ages for just that reason. If you want something more detailed, the kids version will give you enough context to be able to find and understand it.

Each one of the steps in the scientific method has its own standard set of rules intend to guide the scientist toward truth while circumnavigating the scientist’s own biases. Experiment design is a big part of this.

Controls are necessary. Scientists use an experimental group and a control group when doing experiments in order to have a basis for comparison.

For example, when I was in sixth grade, I tested my fifth grade teacher’s running program to see if it impacted lung capacity. I measured the lung capacity of her entire class of students periodically throughout the term. This showed a growth in lung capacity, but that alone was not enough information to determine whether there was a correlation between the running program and the changes in lung capacity. Other variables abounded, such as the changing seasons, the natural growth of children over time, and so on. In order to determine whether there was a correlation, I needed to use a control group which had all the same variables except the running program. I used the next door fifth grade class in the same building, which did not have a running program. This group did not show any growth in lung capacity, making the data I collected far more useful.

Note: If the class I used for my control group had been kids of a different grade, or at a different school, or if I had collected the information during a different part of the year, then it would not have been a good control group because here would have been more than just one variable that was different between the experimental group and the control group.

When evaluating scientific information, claims, and journalism, keep an eye out for problems with the scientific method or with control groups. If you can’t determine whether these things were done properly, it’s best to disregard the information as unverifiable. It may be true, or it may not be. Not knowing is part of science. Get comfortable with not knowing.

Part 2: The Reality of Science

The reality of science is a bit imperfect compared to what popular media has to offer. Have you ever watched a science fiction show where a character uses a handheld device or other instrument to “scan” something, and instantly finds out a whole pile of information about the object in question? That is pure fiction. The real world doesn’t have that kind of technology yet, and likely won’t in our generation’s lifetime. If a scientist needs to test a water sample for contaminants, for example, that scientist will need to run a separate test for each potential contaminant, and each of those tests takes time. The length of time ranges from minutes to days depending on the procedure. For bigger projects, such as studying a new phenomenon, science takes months or years, sometimes even decades, to produce reliable conclusions.

The reality of the timing involved in science is one of the key concepts you can use when fact checking science articles. Claims of detailed knowledge of brand new phenomena are probably not based in evidence, whether or not they end up turning out to be correct guesses. Think back to when Covid-19 first started. Remember all the firm claims that ended up being wrong? Be wary of science reporting about new phenomena, especially if the reporting doesn’t take into account the concept that “we don’t really know for sure yet” in the language.

In addition to limitations, science is subject to bias. This is true both of scientists when conducting science, and of reporters when engaging in science reporting. Scientists are products of our own cultures, which means our biases influence the way we think, and therefore the way we design experiments and interpret the results. This is especially prominent in anthropology (the study of humans), but all other scientific disciplines struggle with this as well.

In order to help prevent biases and other issues from harming the validity of the scientific body of knowledge, scientists participate in something known as “peer review.” When science journals publish scientific research, the process involves having other scientists who did not work on the project review the documents, procedures, and conclusions for proper scientific method and accuracy. This process is very rigorous. When fact checking science, look for peer reviewed articles.

And finally, be aware of the limits of scientific observation. There is a lot we don’t know about, due in part to simply not having the technology to allow us to observe it. Not knowing is part of science. Get comfortable with not knowing, with being willing to hold space for an unknown rather than trying to fill it in without having enough evidence to do so.

Part 3: Understanding The Numbers

Numbers are a big part of science. We use them to describe our observations so that other people can understand what we witness. We also use them to do calculations to figure out more information about our observations.

As you might already know, math can get very complicated. However, you don’t have to go learn calculus or statistics in order to be a discerning individual when it comes to evaluating scientific claims. That said, the most important math to understand for this purpose is probably statistics. Statistics are often twisted, misrepresented, and simply misunderstood in science journalism and by politicians.

Please pause after this paragraph to watch the 12-minute video embedded below to start to get a basic idea of how statistics works. If there are vocabulary words you don’t understand, then pause the video and look them up before continuing. This video contains example problems to do on your own. You can use them to evaluate your understanding of the concepts. If you can do them, then you have a grasp of this knowledge and can use it when evaluating scientific claims. If you can’t, or if you choose to skip them, that’s okay too – it means that you know you don’t have a strong enough grasp of these concepts to evaluate related claims. If this is you, then it is important to remember to put any statistical information you see in the “I do not know if this is true because I am not able to evaluate it” box in your head rather than immediately believing or disbelieving it. Again, get comfortable with not knowing.

When you are reading about science, activate your critical thinking whenever you see numbers. Are units provided? If something went 13 kilometres, that’s a lot farther than 13 feet. Are numbers presented in a way that makes sense? For example, looking at the total number of deaths due to Covid-19 between countries is not as useful as looking at the total number of deaths per capita. “Per capita” means “per person.” This is how to adjust for population size. Think of it this way: If 1,000 total people die in Rhode Island, that’s a lot different than if 1,000 total people die in California because California has so many people in it. If 1,000 people die per every 5,000 people in Rhode Island, then it is the same rate of death as if 1,000 people die per 5,000 people in California. This is why “per capita” numbers are often more useful than total numbers.

Part 4: Reading Scientific Literature

If you have never read a scientific study before, it can look daunting. Studies are filled with scientific jargon making them difficult to read, even for scientists. The key is to read them more than once, look up words you don’t know, and focus on specific parts of the study.

The abstract is a good place to start. This section summarizes the process and results of the study. Sometimes the abstract has all the information you need to fact check the article or meme which was supposedly based on the study. The other parts of the study are valuable if you wish to gain a detailed understanding of how the study was run, especially if you wish to evaluate whether it was done properly.

Part 5: Evaluating Articles

As mentioned above, research journalism is rife with bias and outright error. Be skeptical of headlines designed to evoke an emotional response. Here are some practical questions to ask yourself when evaluating articles that make scientific claims:

  • When was this article written? If it was written a long time ago, have there been new breakthroughs since then?
  • Who wrote it, and why? How might that bias the writing?
  • Does the article site its sources, including links to any scientific studies the article claims as sources? If not, disregard the entire article as it is not credible.
  • Do the abstracts of the original studies actually support the claims in the article?
  • If the article uses numbers, does this article use them in a way that makes sense?

Part 6: Sharing Information

If you struggle with holding space in your mind for the unknown, it may be difficult to read false information without absorbing some of it into your belief system. There is a big difference between believing something yourself and asking others to believe it. To ensure that what you share with others is true, it is a good idea to create a system for determining what you will share. Consider these questions:

  • Have I actually fact checked this, or am I only sharing it because it fits with what I already believe?
  • Am I sharing this because it is true, or because I would be allowing my anger, hope, or another emotion press the share button for me?

Sometimes you won’t be able to fact check something. Maybe it relies on statistics you don’t understand, or maybe there is a paywall between you and the original study. If you can’t fact check it, then what? What do you do with that informational meme or science article which makes a really good point, but which you are struggling to fact check? In my opinion, you scroll past it, or you find an expert to ask about it. Don’t share what you can’t fact check.

Consent, Boundaries, and Men

Content notice: This post discusses a variety of types of non-consensual touch.

One day, in a friend’s large living room that was filled with burners (as in, people who go to Burning Man regularly), a friend of mine and I held a tickle war. It is important to note here that I have an unfair advantage in tickle wars: I am not ticklish. As the room egged me on, my friend became debilitated by laughter and my fingertips. All of a sudden, the words “no” and “stop” mixed in with my friend’s laughter. I immediately stopped tickling.

“No, you’re supposed to keep going,” one of the onlookers said. The rest of the room took that as their queue to cheer me on, some adding the flavor of shame for stopping.

“No,” I said firmly. “He said ‘no.’ That means I stop.”

The room went totally silent for several long moments while everyone pondered what I had just said.

“I never thought of it that way before,” someone finally said aloud. Others nodded quietly.

When I reflect on that story, it always reminds me about how tickling children can be a fun game, but it can quickly turn into child abuse when adults don’t stop. Yet here we were as adults, and everyone but me was still willing to keep going right past my friend’s very clear “no” and “stop” statements. Perhaps if today’s adults had experienced respect for our boundaries as children, we would not be doing things like this to each other as adults.

Consent is about making sure that what we do fits within other people’s boundaries. Boundaries vary from person to person, moment to moment, and context to context. The only way to know what someone’s boundaries are is to communicate about them. Using society’s idea of what’s okay to do to another person’s body in lieu of discovering what someone’s boundaries are and following them often results in stories like the one above – at best. I stopped. Many people don’t. The rest of the people in that room wouldn’t have, although some of them changed their tunes after that incident.

The friend from that story was one of many male friends of mine who have thanked me for respecting their consent over the years. Women, agender, and nonbinary people tend to simply expect it of me. If they feel grateful, they do not say it. It’s the men I know who get surprised and thankful when I do things like immediately stop, or refrain from making a big deal out of it if they say no to kissing or sex. It’s the men in my life who aren’t accustomed to thinking of respect for consent as a minimum standard.

One of the friends I share a bed with in the literal sense is extremely attractive to me. He knows I would make out with him at the drop of a hat if he wanted to. He also knows that I know he doesn’t want to. We have had the same conversation about it several times, and it goes something like this each time:

“I know you want to kiss me and I just want to say thank you for not pushing it.”

“Of course. It’s your body, your rules.”

“Would you please tell that to all the femmes out there? None of them seem to get it.”

Cue: his venting rant about past experiences with women and femme enbies pushing his boundaries, berating him for not kissing them, and other related traumas. (“Enby” is a word for a person with a nonbinary gender.)

This friend is not alone, and is not the only man who has thanked me for respecting his sexual boundaries without qualms. Many men have also confided similar and related stories in me, encompassing a wide range of sexual abuse and coercion from people who aren’t men. In fact, just about all of the people who have personally confided in me about having been roofied or otherwise drugged are men. The kicker, though, is how many of the men who confide in me do not recognize that the stories they are telling me are about consent violations. Sometimes my man friends don’t even recognize rape for what it is when they are the victims.

“If this had happened to a woman, what would you say it was?” I asked one friend after he confided in me with a haunted look on his face and confusion in his voice and words. He froze for a long moment before responding.

“I…I would say, ‘that was rape.’ But…” my friend’s voice trailed off and he stared at me. After he cried for a while, I got him connected with resources for where he could go for help healing from the trauma. He is not alone.

One of my partners who is a man once laughingly told me about a locker room game he played with other boys in high school. It was called “ball check” and involved yelling “ball check” and then slapping other kids in the balls with rolled up towels. Participation was mandatory as stepping out of the game was met with instant social punishment, sometimes verbal and sometimes physical. When I pointed out that this was literally a game based on sexual assault, my partner paused. He had never realized this before our conversation.

My partner is not alone in his experience of childhood “games” that strip away the ability of boys and men to recognize their own boundaries from a very young age. Transgender men are often horrified by what they discover about this upon entering men’s spaces for the first time. Many have told me that it appears from their point of view that by the time cisgender men are all grown up, they have lost any sense of their own boundaries and it thus makes horrifying sense that they violate others without even recognizing what they are doing for what it is.

I have heard it said, “Don’t teach women how to avoid getting raped, teach men how to stop raping.” I think that’s very good advice, and I also think that starts by making sure men know what consent and boundaries look like. After all, consent is about understanding other people’s boundaries in order to operate within them. Teaching men not to rape therefore relies on a prerequisite: Teach men what boundaries are. This starts with helping men understand their own boundaries and teaching them to maintain them. This skill set is difficult to learn for many people, but with men, our culture actively deprives them of the tools they would need to learn it, and replaces these lessons with opposite content. If we want to give men the chance to discover their own boundaries and learn how to maintain them, then we need to respect men’s boundaries and consent.

We must begin to respect men’s personal body boundaries and teach our boys that their consent matters, or we will continue to live in a world with excess trauma caused by men – especially cisgender men – continuing to violate each other’s and everyone else’s boundary lines in ways that extend way beyond sexual boundaries.

So, here is my challenge for you, dear reader. If you aren’t a man, think carefully about how you interact with men moving forward. Is your defense game so strong that you forget that their consent matters too? Pay attention to how you treat men and afford them the same courtesy of basic consent respect that you expect as a minimum standard from them. And if you are a man? Unfortunately, the work to figure out what your boundaries are and how to enforce them falls on you, as does the work to figure out how to recognize and respect other people’s boundaries. Therapy is a great way to make that go a lot faster. Think of it like using an expert’s degree and experience as a tool to make your self-growth flourish faster. Good luck, and make sure you pick someone with a relevant specialization if you choose to utilize therapy.

I’ll leave you with this glorious video about consent and how it works. The video was made with regards to sex, but it’s also applicable to all other forms of touch or intimacy:

The Power of Unconventional Freedoms

Among other hats, one of mine is “teacher.” I teach workshops to adults, art to children in after school programs, and more. One of the most powerful tools I have found I have as a teacher is the choice to allow what I call unconventional freedoms.

Kids in my class can talk about controversial subjects, go to the bathroom whenever they wish, and choose whether to sit or stand. These freedoms are allowed by some teachers, denied by others. What I mean when I say unconventional freedoms goes beyond this.

My kids can cry in class if they want to. They can walk away from their projects and go lay down on the floor. They can stim (engage in repeated body motions that cause no harm to themselves or others). They can do things considered strange or inappropriate by adults in larger society so long as they are not interrupting me, distracting other students from their work, or causing harm.

These unconventional freedoms allow children the space to grow as people and to explore who they are and how to exist peacefully with others.

Dr. Carol Dweck‘s research about the growth mindset (a mindset which involves believing in one’s own ability to grow in terms of skills) tells us that when children have the support to build a growth mindset, they are able to grow more than children who have a fixed mindset (the belief that they cannot grow in terms of skills). This doesn’t just apply to academic topics, Dweck tells us. It also applies to behavior.

Dweck’s research supports treating behavior like another subject students learn right along with English and math. This means supporting them through conversations meant to help give them the tools to grow and do better rather than tearing them down with punishments. Besides, as most teachers or parents can tell you, when children feel supported, they act out less to begin with.

In most of my art classes for children, there are one or two kids who are easily and vocally frustrated with projects. “I can’t do this” is a common refrain among them, indicative of Dweck’s framing of the fixed mind set. “It’s too hard, do it for me?” they ask. “I can’t do it right,” they pout, staring at the project, either dejected after a single attempt or afraid to even start.

To “I can’t do this,” I say, “Yes you can. It’s just hard. You have to try a bunch of times before it will work. This stuff isn’t easy.”

To “It’s too hard, will you do it for me?” I say, “Of course it’s hard. It’s something new. It’s only easy for me because I’ve done it a lot of times. Unless you do it a lot of times too, it will always be hard for you. Try again, okay?”

To “I can’t do it right,” I say, “That’s okay. It’s okay to mess up. It’s okay to make mistakes. That’s part of learning, and that is valuable. Besides, sometimes in art our mistakes take is in new and interesting directions, and that can be exciting!”

By the time they are done working with me for the semester, they try. They attempt. They give themselves the space to fail and try again, just like the other kids. I see them go from a fixed mindset to a mixed or growth mindset. Of course, it helps that it’s an ungraded after-school art class. I have a lot of freedom in my class compared to the daytime teachers.

Which brings us back to the point: Freedoms. How do unconventional freedoms play in to all this stuff about transforming young minds from fixed mindsets to growth mindsets? I consider them to be a highly useful tool set. Here’s an example of why:

On the first day of class one term, a child sat staring silently at the project on the table. Everyone else happily worked away. This child remained still. I checked in with the kid, who then began bawling. “I can’t do this,” the kid wailed. “It’s too hard!” We had the same talk I always have with kids who say these things, but this kid was having a huge emotional response to the situation. The kid understood what I was saying and accepted it, but first needed to cry to get all that emotion out of the way. I let the kid cry on the carpet at the other end of the room, but not before making sure to say, “Come back whenever you’re ready, okay? Take as long as you need.”

Weeks passed and that kid continued to struggle. “It’s too hard,” and “I can’t do this,” came out every single class session at first. One day the kid even moaned, “Don’t you have anything I can do that is perfectly easy for me to do on the very first try?!” Talk about an explicit fixed mindset! I didn’t give up. The more I encouraged that kid to try anyway, the easier it got. Eventually the trips to the carpet to cry without distracting others from their projects stopped. By the end of the semester, the moment that would have prompted “I can’t do it” instead inspired mere hesitation, and a glance at me for encouragement.

None of this would have been possible if I had told this kid not to cry in class. Or not to lay on the floor. Or not to do both at the same time. The unconventional freedom of crying on the floor without shame allowed this child the emotional space to develop a necessary life skill, and it harmed no one.

Speaking of harming no one, that is one of the major lines I draw. Boundaries are necessary after all. In my art classes, there are three main types of rules that everything else I list to my kids as rules comes down to:

  1. Consent. Do not touch other students or their projects, or me or my bins of project supplies, without first asking for and receiving consent.
  2. Class Focus. Do not distract other students from their projects or from me when I am talking. No yelling or other loud noises unless it is an emergency.
  3. Do No Harm. Do not harm others or their projects, or any other property.

These underlying foundations mean that when I ever do stop a child from doing something, I have a really good reason. I will explain it if asked, or sometimes without prompting. The kids appreciate this. After all, kids are people, and people do not like being controlled arbitrarily. Kids just don’t have enough world experience yet to guess at my reasons sometimes without it being explained. On that note, children also thrive when given genuine connection and discourse in lieu of punishment, just like adults do. Here is an example of that:

Two kids in one of my classes were friends outside of class. They always picked the same colors on purpose and got along really well. One day, one of them kept grabbing the other’s arm and pushing and shoving. After the second time I verbally reminded this kid about the relevant rule, and heard it broken a third time, I said, “Hey [name], why don’t you come over here with me? Let’s have a little talk.”

As we walked, the kid looked troubled and closed off. Away from the class, at the other end of the room, I knelt down to be on the same level of the kid.

“What can I do to support you?” I asked. “What do you need to follow this rule?”

By the time I finished the first question and began asking the second, the kid was bawling. The moment this poor kiddo realized I wanted to provide support, all the walls went down and the tears came out. We talked about it through the tears, and I learned that this first-grader wanted the other kid to stop engaging in conversation. “Does [name] know you don’t want [pronoun] to talk to you?” I asked. Turns out this kid had never even thought to use words to establish a boundary line. Skills like that are things people have to learn. Heck, I know adults who still need to learn that one! Anyway, by engaging this kid in conversation with the same amount of respect we give adults instead of giving in to frustration over broken rules or conventional punishment systems, I was able to use the unconventional freedom of “have a discussion instead of a time out” to help this kid learn a valuable life skill. This kid went on to employ that skill in the classroom.

When kids actually do cause harm, they need to be stopped and educated so that they do not continue to do harm. However, much of what adults stop children from doing does not constitute harm. How much harm does that do, especially when we remember that children are people too? What is the point in curtailing freedom when no harm is being done to any person or any thing, if firm boundaries are in place around those very important lines?

Nine Influential Women and Transgender Scientists to Know

Image of Rosalind Franklin
Rosalind Franklin

Rosalind Franklin (1920 – 1958) was a white English chemist and X-ray crystallographer, photographed DNA before the men who are credited with its discovery figured out other things about it. Her work was essential to figuring out other structures as well, including graphite and viruses.

Image of Dr. Maathai
Wangari Maathai

Wangari Muta Maathai (1940-2011) is the Kenyan researcher who initiated and lead Africa’s Green Belt Movement, a project which spread across the continent. Due to Dr. Maathai’s efforts and encouragement, over 30 million trees have been planted. She was Africa’s first woman to win the Novel Prize.

Stephanie Wkolek

Kevlar was invented in 1965 by Stephanie Kwolek (1923 – 2014), a white American chemist. She was one of the very few women working as a chemist for Dupont (a very large chemical research company). Her coworkers laughed at her and the fibers that formed in one of her experiments. Bet they aren’t laughing now.

Image of Dorothy Vaughan

Dorothy Vaughan (1910-2008) was a lead human computer for NASA when the organization began to transition from human computers to the early room-sized computers. She taught herself computer programming and became NASA’s first black woman team leader amid an environment swirling with both racism and sexism.

Image of Marie Curie
Marie Curie, sometimes also referred to as Madame Curie

Marie Curie (1867 – 1934) was a Polish and naturalized-French physicist and chemist. Even now, she is the only person to ever receive the Nobel Prize in two different sciences, and the first woman to be awarded one at all. She was friends with Albert Einstein, who wrote her a very touching letter of support when the man-dominated field turned ugly and vile towards her for being so good at what she did while also being a woman. You can read it here. Fair warning: it made me cry! She died young due to heavy exposure to the radiation she discovered. As she was the first person to work with it, no one knew yet that it was dangerous.

Image of Chien-Shiung Wu
Chien-Shiung Wu

Chien-Shiung Wu, 吳健雄, (1912-1997) was a Chinese-American experimental physicist famous for the Wu experiment, which proved that parity is not conserved. Her discovery earned her the Wolf Prize in Physics in 1978 and contributed to her colleagues winning the Novel Prize in Physics. Her various significant contributions to nuclear physics earned her nicknames such as “First Lady of Physics” and “The Chinese Madame Curie.”

Laurence Michael Dillon

Laurence Michael Dillon (1915-1962), a white Brit, was the author of “Self: A Study in Endocrinology and Ethics,” which may be the first book about transgender identity and gender transitioning. He described transgender identification as innate and unaffected by psychotherapy, and advocated hormones and surgery as an alternative. He is the first person known to have undergone phalloplasty (surgery to create a phallus), and personally aided in the surgery of Roberta Cowell, Brittain’s first patient to undergo bottom surgery.

Ben Barres

Ben Barres (1954 – 2017) was an American neurologist who worked at Harvard and revolutionized our understanding of the brain (primarily by showing that the importance of the glia). He was well known for being a good mentor and for bringing people of other minorities up with him. He was also the first openly transgender person in the National Academy of Sciences.

Image of Lynn Conway
Lynn Conway

Lynn Conway (born Jan 2, 1938), is a white American computer scientist who is credited with work used in most modern computer processors today. Her journey involves being fired for revealing that she was a woman who intended to transition to female both medically and in terms of gender role. Transitioning caused her to lose access to her children because of the law at the time. She started a new life in “stealth mode” where she got a new programming job without telling anyone she was transgender, and eventually came out again after it was safer for her to do so.

Transphobia and Racism are Inseparable in Western Cultures

Below, “(x)” is used to provide links to sources for and further reading related to preceding sentences.

When people of various European nations colonized huge chunks of the planet, part of the process involved replacing aspects of the cultures they conquered with aspects of their own. (x) In this process, genders and sexualities that did not fit into their beliefs were purged along with any religious or spiritual practices that could not be folded into the conquering nation’s Christian ideals. (You can read more about Christianity as a tool of colonialism here and here.)

Across the planet, people of various cultures have had more than two genders for a very long time, such as the Navajo, ancient Jewish societies, the Bugis of Indonesia, and many more. These were often erased by white colonialism, just as queerness was also vilified. After generations passed, cultures which once held space for various kinds of LGBTQIA people lost that capacity. India is a great example of this. Where they once had more than two genders and some branches of the Hindu religion celebrated same-sex love, it is now unsafe to be openly gay in much of the country and people who aren’t men or women are now highly stigmatized. The original law that criminalized same-sex action was put in place under British rule, which ended in 1947, but it wasn’t overturned until 2018 due to the lasting destructive impact of British colonialism on Indian culture. (x) You can watch a short interview with India’s openly gay prince from right before that decision here. Like India, many countries’ homophobic laws came directly from British rule. In fact, CNN says:

“Of the 71 countries around the world in which same-sex sexual relations are illegal, it’s no coincidence that more than half are former British colonies or protectorates, according to research provided by the International LGBTI Association.” (x)

Some cultures have retained their original concepts of gender and sexuality despite the erasure efforts of those inflicting genocide upon them. These cultures are still alive and well. Choosing to insist that the only genders which exist are those recognized by one’s own culture is thus an act of cultural supremacy, and one which feeds into the racist legacy of white colonialism. Transphobia and racism are inseparable in this way.

Dominoes for Teaching Fractions, Decimals, or Division

Choose a set of rules for dominoes, then pick one of the following variations on score-keeping:

For Addition of Fractions

  1. Each player keeps track of points individually. For competitive games, individuals keep track of their own scores. For cooperative games, each player keeps track of the total score of the game.
  2. As players place tiles, the numbers represent fractions rather than integers. The number on the end touching the existing tile is the numerator, and the number on the free end is the denominator.
  3. Each time a tile is placed, the player must add the resulting fraction to the point total.
  4. If playing a version where doubles are played sideways, use this as an opportunity to enforce the concept that it doesn’t matter which number is the numerator; the answer is still 1 point for that tile.

For Long Division and Addition of Decimals

  1. Each player keeps track of points individually. For competitive games, individuals keep track of their own scores. For cooperative games, each player keeps track of the total score of the game.
  2. As players place tiles, the numbers represent division problems rather than integers. The number on the end touching the existing tile is the dividend, and the number on the free end is the divisor.
  3. Players must divide the numbers appropriately to how the tile was played, and add the resulting decimal number to the score total. The facilitator may choose to specify a certain number of digits to be used (i.e. – “round to the nearest hundredth”) depending on the skill level and desired outcomes of the game.
  4. If playing a version where doubles are played sideways, use this as an opportunity to enforce the concept that it doesn’t matter which number is the dividend; the answer is still 1 point for that tile.

For Division with Remainders, Rounding, and Addition of Integers

  1. Each player keeps track of points individually. For competitive games, individuals keep track of their own scores. For cooperative games, each player keeps track of the total score of the game.
  2. As players place tiles, the numbers represent division problems rather than integers. The number on the end touching the existing tile is the dividend, and the number on the free end is the divisor.
  3. Players must divide the numbers appropriately to how the tile was played until a remainder is found. Then, players properly round the answer to the nearest integer and add it to the score.
  4. If playing a version where doubles are played sideways, use this as an opportunity to enforce the concept that it doesn’t matter which number is the dividend; the answer is still 1 point for that tile.

 

Chemistry Games!

There are only a few weeks left in the semester, which means it’s time to create chemistry games for my students to play at our last meeting.

This trivia game is meant to be played in small groups. I will ask the class whether they want to play with cell phones and Google, or without. If they want to play with, then we’ll arrange the groups so that each one has someone with a phone with internet. There are fifteen questions, so they will only get about 5-6 minutes to complete as many of them as they can. When the timer goes off, scores get tallied, and the winning group gets a prize. The answers, the trivia handout linked above, and other chemistry games and resources can be found on the “Chemistry Games and Resources” tab above.

There will also be a chemical equation balancing relay race. Each team will line up behind a line. One person from each team will run to the front of the room, take the top page from face down in their team’s stack, flip it over, balance the equation, and run back to tag in the next team member. I will stand behind the desk to check answers. If the first person got it wrong, the second person must solve the first equation correctly, and must tag in a third person to solve the next equation in the stack. The first team to get through their whole stack wins a prize.

The class has also decided to hold a potluck that last week, so there may not be time for more games. Eating and studying will finish out the hour. I’m so proud of my students. They’ve all worked really hard, and it’s paid off.

Balancing Chemical Equations: Simple Example

I have a lot of people asking for help with balancing chemical equations. Below is my personal method, with a simple example. Click here for a PDF of a redox example.

Feel free to use this material in any way you find valuable. It would be great if you cite bluntrose.com in any handouts, and if you use the printer-friendly 2-page PDF version, it’s already on the page for you.

Directions:

  1. Make a table that shows how many of each element there are on each side of the equation.
  2. Identify an atom that is both out of balance and located in only one molecule on the left, and only one molecule on the right. (If no such atom exists, try to find one that is only in one molecule on one side, even if it is in more than one on the other side.) Start by adding coefficients that balance this atom on both sides. Cross off and update the numbers in your table to reflect the new totals for each atom.
  3. If that was not enough to balance the equation, proceed to the next atom that is in the fewest number of molecules, and repeat Step 2. Continue to do this until all atoms are balanced.
  4. Double-check by re-adding the totals for each atom to ensure that your answer is correct.

Example:

___KI(aq) + ___Pb(NO3)2(aq) ___ PbI2(ppt) + ___ KNO3(aq)

Step 1:

1

K

I

Pb

NO3*

*NO3 (nitrate) can be listed as one unit here because it does not separate. If nitrogen or oxygen appeared separated in the product, or if nitrate was present in the product in addition to oxygen or nitrogen appearing in some other part of this product, then this would not work. NO3 is the same on both sides, so we are able to treat it like a single unit for the sake of balancing this equation.

Step 2:

Iodine and nitrate are the only things out of balance here. Iodine is only in one molecule on the left and only in one molecule on the right. The same is true of nitrate. This means it doesn’t matter which one we start with. Let’s try starting with iodine, chosen arbitrarily:

_2_KI(aq) + ___Pb(NO3)2(aq) ___ PbI2(ppt) + ___ KNO3(aq)

2    1

K

1

2    1

I

2

1

Pb

1

2

NO3*

1

At first glance, this might seem wrong because the potassium (K) is no longer balanced. Take a look at what else is not balanced: nitrate. Nitrate and potassium happen to be in the same molecule on the right, so the next step is to choose a coefficient for that molecule that balances both potassium and nitrate if possible. Luckily, it is!

Step 3:

_2_KI(aq) + ___Pb(NO3)2(aq) ___ PbI2(ppt) + _2_ KNO3(aq)

2    1

K

1    2

2    1

I

2

1

Pb

1

2

NO3*

1    2

This looks balanced now, according to our accounting table. The last step is to double-check to make sure it is right.

Step 4: To check your work, translate the formula into an equation for each element or molecule.

_2_KI(aq) + ___Pb(NO3)2(aq) ___ PbI2(ppt) + _2_ KNO3(aq)

Potassium:

(2 X 1) + 0 0 + (2 X 1)
2
2
Therefore, potassium is correct.

Iodine:

(2 X 1) + 0 (1 X 2) + 0
2
2
Therefore, potassium is correct.

Lead:

0 + (1 X 1) (1 X 1) + 0
1
1
Therefore, potassium is correct.

Nitrate:

0 + (1 X 2) 0 + (2 X 1)
2
2
Therefore, potassium is correct.

FINAL ANSWER: 2KI(aq) + Pb(NO3)2(aq) PbI2(ppt) + 2KNO3(aq)
