How exactly does gender work?

Books have been written about it, alcohol-based dinners never go without it, and more recently, we are digging into what defines it. Put simply, what are the differences between men and women? This TED talk by biologist Karissa Sanbonmatsu really got my attention. First of all because she presents some of the new discoveries from epigenetics and research in DNA that explain the differences between men and women from a biological perspective. Gotta love science. This lesson is filled with tons of scientific vocabulary to describe how DNA works to create gender differences.

However, here is the twist, Sanbonmatsu, a transgender scientist, also talks about the challenges she faced through her struggle with her own identity. This content is layered and complex. On one hand the objective is to help science-based students become more verbal with DNA related vocabulary–an important corner stone topic for biologists. But beyond that, the speaker pulls in the social challenges of the “old boys club” that exists in the scientific community as well as the very misunderstood transgenderism.

Pre discussion

What are some of the theories you have heard about the differences between men and women?
Do you think there are differences?
What does it mean to be transgender?

The Video: The Biology of Gender

There are really two aspects in this video mashed up together. 1) Sanbonmatsu shares the science of gender. 2) Sanbonmatsu talks about the reactions of her scientific community towards transgenderism.

I would first untangle each aspect.

What does the latest research tell us about gender?
What is the behaviour of our DNA?
How is Sanbonmatsu contributing to a society of tolerance inclusion?
Why does Sanbonmatsu expose the scientific community as being especially hard on her choices?
Do you think there are other social circles where transgenderism is more difficult?
What about less difficult?

I leave you with that for the weekend…have a good one.

What’s the weather today?

I love talking about the weather. It is the easiest way to initiate a conversation with a stranger or acquaintance if you need to break the silence. Great for elevator rides, spontaneous waiting time and warm repartee.

It is also a ubiquitous element that can have multiple impacts on our lives. Indeed a rainy day, bright sun, or a snowstorm will change how we dress, the meals we eat, the activities we plan and perhaps how we get to work. Personally, I check the weather every morning because I take my bike to work–even in winter.

Moreover, I find weather phenomena fascinating. Tsunamis, earthquakes, tornadoes, nature has a way of reminding us who is really in control. Beautiful, powerful, terrifying the planet is a person. She breathes, she aches and she speaks. Are we listening?

This particular discussion lesson goes from general to scientific to silly. The objective is to elicit the vocabulary around a familiar topic and add a level of complexity with either the science behind weather or weather-related expressions. I just couldn’t choose, so I put everything.

Pre discussion

What are the different types of weather or climate you can name?
What affects the weather?
How does the weather make you feel? When it rains, when it is sunny, when the snow falls…
Do you use the weather forecast to plan activities?
What activities do you do in spring, summer, fall and winter?
What are the seasons like in your country?

Option 1: The Video: The Science of Weather

Divide the video into 2 or 3 segments and do a Tell Back of the main themes and words
How do meteorologists sort through information, identify trends, and make predictions?
Why do they often get it wrong?
Why is it important to predict the weather?

Option 2: Weather idioms

For this, I made a handout and some flashcards. They are on Teachers Pay Teachers TPT. Click to go see.

What are your thoughts on Omicron breakthrough infections?

Great ESL lesson to explore the information about breakthrough infections and on Omicron.

Level: B2, C1, C2
Activity: True/False handout on TPT (0.99$)

Language focus: emotions vocabulary, science, health
Media: video

What are your thoughts on Omicron? Are you frustrated that despite all your efforts, people (maybe even you) have gotten sick? Are you afraid of the next variant? Are you vaccinated, boosted and wondering why you bothered? Or do you see Omicron as the beginning of the end of a pandemic that has changed us in so many ways we still can see the forest for the trees? Perhaps you see Omicron as a blessing, a harbinger of better times yet to come.

All of the Above

If I am being totally honest, I feel all those things. I am vaccinated, boosted, wear my mask everywhere I go, wash my hands obsessively and analyze every sneeze, cough and sniffle with scientific discipline. I am a goody-goody who did everything public health officials recommended. Do I regret it? No, absolutely not? Do I sometimes wonder if it was too much? Yes, sometimes.

Give me the Facts…Again

That is why I really appreciated, Jo Hanson’s video Here’s What I Learned from Getting COVID. The host of PBS’s It’s Ok to be Smart is pro-vaccine, pro-mask, pro-anything-that-will-protect-the-population (see Masks vs. Corrona, lesson), and got COVID anyway. He candidly shares his frustration. Still, without defending or trying to convince, he diligently gives a fact-based explanation of why this happened and why it is still important to do everything in our power to stop the spread.

Warm-up

Elicit people’s thoughts on Omicron: is it a blessing or a threat
How does this new variant make them feel? Helpless, no big deal, ready for another wave, discouraged, scared.
What do we know about the virus?
(I would stay away from a pro or against discussion on vaccines if I were you)
Go through the statements on the handout and make predictions of the answers

The video: It’s Ok to be Smart– Here’s What I Learned from Getting COVID

Discussion

You can use the handout to talk about the various points made in Jo’s talk
What do you think are the key ‘take-aways’ on vaccines, the severity of Omicron, what attitude we should adopt to stay safe AND stay sane?

Why do we believe weird things?

Level: B1, B2, C1
Handout on TPT

Media: Video
Language focus: beliefs, superstitions, conspiracy theories, fake news, disinformation.

Why do we believe weird things?

Fake news, misinformation, disinformation, these concepts are all over the media. We all know it’s out there, but how can we tell what is true and what is fake? First, let’s play a game…

True or False

Salt makes water boil quicker.
You should never swim right after you eat
Some people are more right-brain thinkers and others more left-brain thinkers.
Toilets flush differently in the southern hemisphere than the northern hemisphere.
Einstein failed math.
Humans and dinosaurs co-existed
Vaccines cause autism.
You need to wait 24 hours to file a missing person’s report.
We use only 10% of our brain.
Most of our body heat leaves through our heads.
You should never wake a sleepwalker.
Bats are blind.
Alcohol keeps you warm.
Sugar creates hyper children.
Your hair and nails keep growing after you die.
Slaves built the pyramids in Egypt.

In case you use this to generate discussion with your class, I won’t give you the answers. You could invite your students to check for themselves at Readers Digest.

It’s your brain’s fault

Famous debunker and Skeptic.com’s editor-in-chief Michael Shermer gives us a bit of insight into how our brain is wired to makes us believe weird things. He explains and demonstrates how things like priming and cognitive bias are natural neurological predispositions that lead us to faulty conclusions. This discussion utilizes vocabulary in both pure science and psychology to demonstrate, in very cool ways, how media can create what I will term “information blind spots.”

Lesson Notes

***Caution! I did this lesson with a high intermediate student and they were overwhelmed with Shermer’s speed. I would recommend slowing the video down and using this True/False handout to explain and explore some of the vocabulary and concepts in the video. Have your students read through the statements and make predictions about the possible answers. Then have your students watch the video to confirm or correct their original impressions.

warm up

Go through the handout and predict which statements are true or false.

The Video: Why People Believe Weird Things

Discussion

What makes us believe weird things…make a Mind Map of all the elements you hear?
Are you a skeptic?
Why don’t we listen to science?

Enjoy!

What bad habit would you like to break?

Why are bad habits so hard to break?

First, let’s clarify that a bad habit is a negative behaviour pattern–perhaps one that causes bodily harm. So if your daily glass of wine is not causing you harm then it can stay (yay!)? However, if you drink a whole bottle, text old boyfriends/girlfriends or pass out on the sofa, that may be a different story.

Without being too hard on ourselves, I’m sure we can think of at least one bad habit. Mine…I stress eat. When I get stressed, I feel hungry, crave sweets (I don’t even like sweets) and I’m always looking forward to my next meal.

But why?

The creators of ASAP Science YouTube channel look at bad habits from the scientific perspective. They explain why we feel the need to repeat behaviours even when they hurt us. Let this scientific explanation take the guilt out of your bad habits and give you something interesting to talk about with your students.

Pre discussion

Mind Map a list of bad habits.
What are your bad habits?

The Video: How to Break Your Bad Habit

What are some of the bad habits mentioned in the video?
How much of our behaviour is done out of habit?
Can you explain “chunking”? What does it do for us?
Can you name the elements in the 3 step loop?
How can you change a habit?
Now think of your own bad habit…what do you think it provides for you? (e.g. a rest, socialization, a break from boredom, a break from stress, etc…)

Let me know how the discussions turn out. I love to hear from you.

Would you like to visit Mars?

Would you like to visit Mars? At one time this would have been a question to engage in hypothetical thinking, but now, it could be a real possibility. According to the Washington Post, NASA expects that trips to Mars may be possible in the next 20 to 25 years. In fact, they have launched an exciting competition calling companies, universities and anybody to build models of habitats for Mars.

And if you were to go, what would you bring? Some baggies to collect Mars sand? A good pair of shoes? Camera (of course)? It is an interesting thought to play with. Thus in this post I am referencing the Washington Post article Where to stay on Mars? Robots could create living quarters before humans arrive. The article is featured in the Kids Post, so the vocabulary is relatively simple. And the subject matter may spark some interesting discussion about basic needs, isolation, and exploration.

Pre discussion

Would you like to go to Mars? Why?
What do you think it will be like? Dry, hot, cold, lonely, weird, exciting?

The article: Washington Post Where to stay on Mars?

Questions

To get the gist of the article, do a series of Tell Backs for each section
What are some of the things that have to be planned in order to make this possible (food, habitat, etc…)?
What is the habitat competition all about?
What kind of entertainment would you bring if you were to stay a year?
What would you put in your suitcase?
How do you think visiting Mars will change life on Earth?

How do we test new medicines?

Clinical testing of new medicines and therapies is quite a layered and rigorous process. And still, when a drug reaches the general public, there can be unexpected outcomes. This TED talk features Nina Tandon introducing a new biotechnology process that may prevent some of these outcomes.

For your science students…and perhaps your science aficionados, watch Tandon’s presentation and see if your participants can pull out the main points and features this new technology offers.

Pre discussion

What do you know about the process of drug testing?
Do you think the process is solid enough to protect against unpredictable outcomes?
What could be improved?

The Video: TED-Could tissue engineering mean personalized medicine?

Cut the video into as many parts as you need depending on the level of your participants.
Do a Tell Back and Mind Map of the main points
What are the features of this technology that improve on what was done in the past?
How would it change the current practices in drug testing?

What is in your food?

We live in a fast paced world with all kinds of conveniences. Food taking a huge chunk of the convenience market, many foods are processed and packaged to serve. If food and nutrition are a topic of interest to you and your students, you might find this National Geographic article about Henry Heinz rather interesting.

Pre discussion

What concerns do you have about food?
What do you look for when you read the labels on packaged foods?
What are your ‘rules of thumb’ when food shopping?

The article: How Henry Heinz used ketchup to improve food safety

Mind Map the main points of the article
What were some of Heinz’s values?
How did that affect his products?
Do you think today’s food producers are concerned about the same things as Heinz?
What can food producers learn from this story?
