STEM Tuesday– Survival Science — In the Classroom

By on June 11, 2024   /   STEM Tuesday, Survival Science  

 

When we talk about animals, we are usually talking about their biological make-up: How they look, what they eat, where they live, and how they interact with other animals. But this month we are focusing on a different topic. It’s more about how animals survive in the wild. This is an important idea and one that is a good to explore with your students. Especially because as climates change and humans move into their habitats, animals are needing to work harder to survive.

There are many great books to use in the classroom on our Species Survival  list this month. Here are a few activities that you can use in your classroom:

 

Hopping Ahead of Climate Change book

Hopping Ahead of Climate Change: Snowshoe Hares, Science, and Survival

by Sneed Collard

This book takes a look at whether animals are able to adapt to climate change to survive. The snowshoe hare is white because normally it is found in areas with a lot of snow. But if those areas have shorter snow periods, its white coat, which normally allows it to hide in plain sight, becomes a very big hindrance. So much so, that it makes itself stand out amongst the greens and browns of the trees, grass, and dirt. This is makes it easy prey for a predator!

 

 

Classroom Activity

What traits do animals have that allow them to blend in with their surroundings. Have the students do some research to discover three animals that use their colors as camoflauge  They can start with the snowshoe hare, but come up with two more. There are many of them to choose from. If they can’t think of any, prompt them with: Snake, shark, giraffe, tigers, etc.  Using these animals, have students answer the following questions:

  1. How does the color of the animal help them to blend in with their surroundings?
  2. Does this animal have a pattern that also helps? and if so, how?
  3. Do you think these colors and patterns help them during specific times of the year?
  4. Would their colors and patterns help more in particular seasons of the year or not?
  5. How would that change if the seasons were lengthened or shortened due to climate change?

Have a discussion with the class. Maybe even have the students draw their animals in their original habitat before and after climate change effects to see the difference.

 

History Comics: The American Bison: The Buffalo’s Survival TaleThe American Bison book

Written and illustrated by Andy Hirsch

While some may be familiar with the history of how great herds of bison roamed across the plains, it might come as a surprise that these creatures not only benefited Native Americans, but also the land on which they lived. This book explores the fascinating ecologicial “triangle” relationship between bison, the prairie grasses of the West, and the Native Americans that lived there. The graphic novel form makes this book easily accessible and fun for kids to read and offers great imagery for teachers to use in their classroom.

Classroom Activity

How can animals actually benefit the environment in which they live? Bison used their own mucus (or snot) to reseed grasses across the prairie. Read the book to learn more about this fascinating trait that allowed bison to also digest the grasses and eat them. Without the bison, the prairie grass had a difficult time growing and expanding across the land. How did the Native Americans help? They provided places with lots of grass for the bison to graze. Discuss how this worked for that environment.

  1. How exactly did the bison use their mucus to eat food?
  2. How were the microbes in the soil beneficial to the bison?
  3. What is cellulose and why is it so hard to digest?
  4. How did the Native Americans use the grasses to bring bison to their area?

Have a discussion with the class about what they have discovered. Can you think of other animals that might have a similar relationship to their own environment?

 

The Nocturnals Explore Unique Adaptations of Nighttime AnimalsUnique Adaptations of Nighttime Animals

Written by Tracey Hecht

This book takes a look at species survival from the point of view of nocturnal animals. But it presents lesser known animals like the pangolin, woylie, tuatara, aya-aye, and jerboa. It not only features facts but also includes narrative stories about each animal so children can learn about the animals’ nocturnal habits and special adaptations.

 

 

 

 

 

 

Classroom Activity

Have a discussion about nocturnal animals and how they interact with their environments. The cool thing about this book is that it allows for a discussion about nocturnal animals that students may not be familiar with.

  1. What traits make an animal nocturnal?
  2. How are nocturnal animals different from diurnal or crepucular?
  3. Why do you think it might be more difficult for an animal that comes out at night to survive?
  4. Learn about two or three unusual nocturnal animals that you may not have known

Have students pick one nocturnal animal, unknown to them, and draw it, give 3 clues about its habitat, and discuss how it might survive. Have them present their animals to the class. You could even do this as a “Name that animal” type of game and have the student give clues while the other members of the class guess what it is.

 

The other books in this list all lend themselves to wonderful discussions in the classroom about how animals survive in the wild. Many of these authors also have more information on their websites. So be sure to check them out! This is a great topic for getting your students excited about animals, and getting them to explore unusual environments as they consider how they have a impact on the world.

STEM Tuesday — Astronomy/ Eclipse — Author Interview

By on April 23, 2024   /   Astronomy, STEM Tuesday  

Welcome to STEM Tuesday: Author Interview, a repeating feature for the last Tuesday of every month. Go Science-Tech-Engineering-Math!

This month’s featured STEM author is Meg Thacher, author of Sky Gazing: a guide to the Moon, Sun, planets, stars, eclipses, constellations (Storey Publishing, 2020). Meg teaches astronomy at Smith College and is the academic director for Smith’s Summer Science & Engineering Program for high school girls. Plus, she writes for kids!

Sky Gazing is a fun and fascinating tour of our solar system, with many extra bonus points for its glow-in-the-dark cover! spread from SKY GAZING

Andi Diehn: The format of your book is slightly unusual – it’s big! Why did your publisher decide to go big with this one? What is it about the content that lends itself to taking up a lot of “space” on the page? (pun intended)
Meg Thacher: I think the size (11 by 11 inches), which is similar to many picture books, signals that there will be a lot of illustrations. This large size is not unusual for Storey Publishing’s kids’ books. They publish a lot of how-to books: Backpack Explorer, Cooking Class (Deanna Cook), Cardboard Box Engineering (Jonathan Adolph). All of them, including Sky Gazing, have pages large enough to accommodate diagrams and instructions. Sky Gazing is a book about observing the sky from wherever you are, day or night, with the naked eye. But it also has information on the What causes the Moon’s phases? How does the Sun move through the sky at different times of year? What are the shapes that people all over the world saw in the stars, and what are the stories they told about them? It’s hard to do that that well without illustrations.

Andi: I like how you weave in history, not just science – why is it important for readers to think about astronomy’s role in exploration and culture?

Meg: Astronomy is the oldest science. People started out telling stories about what was happening into the sky, which inspired them to observe these phenomena closely, which in turn helped them to discover the reasons behind them. So those first storytellers were also scientists. It was important to me that readers understand that everyone, everywhere on Earth looked at the sky. No matter who you are, your ancestors were astronomers. And you can be, too!

Andi: I LOVE the hands-on activities! Why include these in the book? spread from SKY GAZING

Meg: This is partly a Storey thing and partly a me thing. Reading about astronomy is fun, but doing activities makes the ideas and concepts more “sticky”. We can read about the path of the Sun through the sky, but if we put a stick in the ground and watch its shadow for a day, we’ll remember it better. We’ll understand the connections between the Sun and shadows, and even deepen that understanding by making a connection to how shadows help us tell time. I use activities in my teaching all the time.

Andi: Your book encompasses your topics from the microscopic examination to a macro view – such as the section on the sun, which includes a discussion of fusion. Did you ever think, when you were writing, whoa, this is way too much for a kid’s book?

Meg: Absolutely! And that’s why there are so many text features. The book is written for kids in grades 4 to 9, which encompasses a huge range of scientific knowledge. I was very careful to check in with the NGSS (Next Generation Science Standards) so that I knew what content was age appropriate. The main text should be comprehensible to a fourth grader, but I wanted to have something for the ninth graders, too. So there are sidebars for them that go into more depth. The fourth graders can skip those without losing the general explanation. Photos and diagrams and pictures illustrate concepts in the text, so that readers have a visual representation of the text. One of my favorite features is the graphic novel sequences. For example, there’s a detailed text description of how the Moon was formed on one page, and a series of panels on the facing page, complete with collisions and explosions. One is engaging, and one provides detail.

Andi: In your book, astronomy is super accessible – you have lots of suggestion for how readers can observe the skies above them, even without telescopes or other equipment. Why is that important to include?

spread from SKY GAZING

Meg: I wanted to make astronomy accessible to everyone. Astronomy can be a really expensive hobby if you buy a telescope. Or very frustrating if you buy a cheap one. The sky is up there for all of us to observe—you don’t have to go to a lab or hike through the jungle to get your data. There’s so much to see, no matter who you are or where you live, with your eyes alone. And if you want to go a little deeper, the absolute cheapest or oldest binoculars will help you do that.

Andi: You’re a college professor – when writing this book for younger students, what did you focus on that might be different from your work with older students?

Meg: Actually, I teach a lot of the same things to both audiences. The courses I teach to my college students are focused on observation, with telescopes and the naked eye. The two main things I do differently when writing for a younger audience are to make sure that the topics are developmentally appropriate and that the material is fun and relevant for kids.

Andi: Your tattoo book is so fun! How did that project come about?! Temporary tattoo book

Meg: My publisher again. Storey has a series called Tattoos That Teach. Topics include butterflies, sharks, dinosaurs, and woodland creatures. Astronomy was an obvious fit, so they hired me to come up with a list of astronomical objects and write the blurbs, and they hired Angela Rizza for the pictures. She’s an illustrator and a tattoo artist!

 

Andi: Is there anything I didn’t ask about your book that you’d like to mention?

Meg: Yes – how it looks! This is down to the illustrator, Hannah Bailey, and the book designer, Jessica Armstrong. When I turned in my manuscript, I included hundreds of diagrams and pictures. I would find them on the web or in books, or make a rough sketch, and these two turned it into a work of art. When I saw the “first pages”—the initial version of the text and illustration, laid out as it would be in the book—I was blown away. From photos and illustrations to page placement and color choices, this book is just gorgeous. It would be a very different book if I was the only involved in its creation.

Happy New Year from the STEM Tuesday Team!

Inertia For the New Year

Painful Inspiration

The weather turned. The temperature dropped rapidly. It was a cold and misty day but the precipitation began to freeze in the late afternoon causing black ice. Typical Kansas weather where the temperature went from the mid-40s to -8 within a 36-hour period. 

No problem. Hunker down, stay warm, and finish the STEM Tuesday New Year’s Post. Easy.

Not so fast. 

I also had to walk my daughter’s dogs who were staying with us. Dog #1 went fairly easily as the dog and human performed seamlessly transversing the ice rink of a sidewalk. Dog #2, however, had other things in mind. Just a few steps past the thawing effects of the ice melt on the sidewalk, a squirrel ran down a tree trunk and sprinted across the ice-crusted lawn. Dog #2, by all measure a champion squirrel chaser, tipping the scales at ~80 lbs., launched with great enthusiasm after the squirrel. 

Time and perception snapped to slow motion. I watched the retractable leash unroll with great speed. Just when it crossed my mind I should probably let go or get my arm jerked off, the line ran out. My arm jerked forward but, fortunately, not off. My feet shot out from under me and I found myself sliding rapidly down the sidewalk incline toward an oak tree trunk located in my path at the bottom of the walk. Just when the inevitable crash was mere seconds away, I had a STEM Tuesday New Year’s Post revelation and screamed, “INERTIA!”

After a few minutes of nursing the scratches and bruises while the rest of the family directed all their attention to the health and well-being of Dog #2, I limped to my desk to capture the moment inertia changed everything. 

(Note: No animals or humans were hurt during this highly dramatized, perhaps over-dramatized, story.)

Inertia. A brilliant and inspirational word! In fact, a perfect word to use as the 2023 STEM Tuesday Word-of-the-Year. 

Throughout our educational journey, we’ve probably been exposed to Newton’s First Law of Motion, a.k.a. Newton’s Law of Inertia, so many times it became rote and not the alive physical law it is. An object at rest or in motion tends to stay at rest or in motion unless a force acts upon it. That’s Newton’s Law of Inertia. 

Inertia is one powerful property and one powerful word to guide us in the coming year.

A Discovery

The year was 1851. It’s deep into a cold January 6th night a few hours after midnight. A young man knelt over his latest experiment in the cellar of the house he shared with his mother at the corner of rue de Vaugirard and rue d’Assas in Paris. He is not considered a great scholar by his peers. Although he has already made several significant advances in science, he is not accepted in the inner circles of the great Parisian mathematical or astronomical minds of the era. Yet, when Leon Foucault released the 5-kg brass bob connected by a wire to an anchor on the ceiling, he made history.

Foucault watched the oscillations as the pendulum swung slowly and gracefully in front of him. Back and forth. Back and forth. Back and forth. Then he saw it. The plane of oscillation had moved ever so slightly away from its initial position. He knew immediately he had done something nobody in history, not even Galileo, Newton, or any of the great scientific human minds, had done. Leon Foucault had proven with his simple, but elegant, pendulum experiment that the earth rotates.

The next month, Focault demonstrated to the scientific community his pendulum experiment in the Meridian at the Paris Observatory. Much debate was raised, especially about how an “amateur” could have made this discovery, but nobody could refute Foucault’s conclusions. The experiment was repeated on a grander scale a few weeks later with a 28-kg bob hanging from a 67-meter wire from the dome of the Pantheon in Paris. The public was invited and people flocked to see the exhibition. Scientists all over the world repeated the experiment and all confirmed Foucault’s findings. Even today, the Foucault Pendulum is a popular experiment to recreate by both science museums and home enthusiasts. In a sense, the inertia of Foucault’s experiment continues in motion to this day.

The STEM Tuesday 2023 Word-of-the-Year “inertia” is submitted for consideration to all creative people in the spirit of Foucault and his pendulum. The whole experiment worked because of inertia and the motion described by Newton’s First Law in the plane of oscillation. When the pendulum moved back and forth, the earth below moved. 

 

Creative Inertia

In order to create, we need to be like Foucault’s Pendulum and use the force of inertia to make our creative world turn. What if on that dark February night alone in his cellar, Leon Foucault wouldn’t have let go of the brass fob? No motion. Which would have meant no discovery. In order for him to prove the earth turned, he had to put the pendulum in motion and tap the power of inertia.

Inertia for 2023 means putting creativity in motion by…creating. Creative inertia!

What fuels creative inertia? Curiosity. A creator is driven by curiosity much like a scientist is.

  • Curiosity about what happens next drives the fiction writer.
  • Curiosity about what actually happened or what actually is drives the nonfiction writer.
  • Curiosity about the image and what it represents drive the illustrator.

Creative inertia grows out of curiosity. Like Foucault, creators need to release the bob and put creative inertia to work. It all starts with a single word or a single mark, followed by one after the other. 

Even if it sometimes (or often) feels like your creative life is static and going nowhere but back and forth, remember the world below is turning. Creative inertia means you are improving. It means you are in motion.

A creator at rest tends to stay at rest. A creator in motion tends to stay in motion.

“The phenomenon develops calmly, but it is inevitable, unstoppable. One feels, one sees it born and grow steadily; and it is not in one’s power to either hasten it or slow it down. Any person, brought into the presence of this fact, stops for a few moments and remains pensive and silent; and then generally leaves, carrying with him forever a sharper, keener sense of our incessant motion through space.”

                                                   -Leon Foucault, describing his pendulum experiment, 1851
