Encourage STEM Thinking This Thanksgiving

bf-banner_stemthinking

The Thanksgiving holiday is one of our favorites here at KiwiCo, because it brings space for quality family time, without the pressure and stress of gift giving (which will be here all too soon!)  There are so many wonderful ways to spend that time together as a family, reflecting on what we are grateful for (see some of our previous posts on creative gratitude traditions (here and here).

This week also presents a great time to help your kids connect with the world around them — whether it’s the wonders of nature or mathematics in everyday life, or – if you’re lucky enough to spend Thanksgiving with extended family – older generations with (perhaps) a different perspective on life.  All you need to do is encourage your kids to be observant and ask questions about the world around them.

Here are some fun & easy ways to encourage STEM thinking (curiosity and creativity!) with your family this Thanksgiving:

For kids ages 3-4:

1. Take a nature hike. Yes, it’s that simple! (Bonus: you can walk off a piece or two of pumpkin pie!) Here are some things to point out:

  • The leaves on trees: Why do you think they change color during fall?

    Pro Parent Tip: When the weather gets colder and the days get shorter, trees stop producing chlorophyll — the stuff that makes leaves green and turns sunlight into plant food. Trees shed their leaves to conserve resources for the long winter. You can find more information about why leaves change color, as well as a kid-friendly guide to identifying different tree species here.

    Kid Challenge: How many different kinds of leaves can your child collect? Why do they think some leaves are bigger than others, or rounder, or fuzzier?
  • Animals in the neighborhood: Squirrels, birds, skunks, raccoons? Where do these animals live, and how do they adapt for the colder temperatures of fall and winter?

    Pro Parent Tip: Animals adapt for colder months through behaviors like hibernation, hoarding, and migration because it gets harder to find food in the winter–they can’t just go to the grocery store like we can! You might think that only bears hibernate, but you’d be surprised!

    Kid Challenge: Do you see squirrels collecting nuts? Where do you think they put them, and why do you think they do that? Do you see any birds flying south for the winter?
  • The sun in the sky: Why does it get dark early at this time of year? Have you noticed that the sun isn’t as high in the sky during winter as it is in the summer?

    Pro Parent Tip: It’s all due to something called an analemma, which describes the Earth’s imperfect orbit (1 orbit = 1 year) and rotation (1 rotation = 1 day) relative to the Sun. Over the course of a year, the Sun’s position relative to Earth makes a figure-eight, because the Earth doesn’t orbit the Sun in a perfect circle, and it spins on a tilt relative to its orbit. For half of the year the northern hemisphere is tilted toward the sun (our summer), and for half of the year it’s tilted away from the sun (our winter). That’s why seasons are reversed between the hemispheres, and why the sun rises higher in the sky during our summer months.

    Kid Challenge: Did you know that when it’s winter here it’s summertime in Australia (and everywhere in the Southern hemisphere)? Older kids might appreciate this video that gives the “reasons for the seasons.”

For kids ages 5-8:

2. Have a geometry lesson – with food! Pies are a great opportunity to learn about circles. For younger kids, ask if they can identify other circle and sphere-shaped foods like Brussels sprouts and cranberries.

Pro Parent Tip: The distance from the center of a circle to its outside edge is always the same — that’s what makes it perfectly round. That measurement is called the radius. The distance from one edge to the other (through the center) is called the diameter, and the distance around a circle (its perimeter) is called the circumference. The ratio of a circle’s circumference to its diameter is always the same, no matter the size of the circle, and that ratio is known as pi! What do you get when you divide a pumpkin’s circumference by its diameter? Pumpkin pi!

Kid Challenge: Prove that all points on the edge of a circle are the same distance to the center by measuring from the edge of a pie crust to the middle of the pie with kitchen twine and a ruler. Older kids can divide the circumference by the diameter of different-sized circles to prove the ratio (pi!) never changes.

3. Have the kids ask older relatives what things were like when they were growing up. How has technology changed? What was most different, and what things are similar? What activities did they enjoy?

(Hint: Our ONLY choice for cartoons was “A Charlie Brown Thanksgiving”, and you could only watch it at the exact time it came on TV, AND you had to watch all the commercials! No on-demand or recording or fast-forwarding!)

For kids ages 9+:

4. Cranberry Catapult: What’s more fun than flinging food at each other WHILE learning about projectile physics? Nothing. Give your kids a few extra cranberries from the kitchen, and tell them to go nuts! Let them experiment with projectiles of different weights and mass — how are the trajectories of lighter or heavier projectiles affected differently by gravity? Just make sure the kiddos take this project outside if they’re using projectiles likely to stain (like cranberries!)

5. Cranberry Invisible Messages: The kids will love this opportunity to pass secret messages the grown-ups can’t read. Take this opportunity to teach kids about acids and bases. In this case, cranberries are acting as the acid that reveals the message. What are other examples of acids and bases? Encourage kids to experiment and see if this would work with another acid, like lemon juice.
