By student request: A show about how you walk, how fish swim, how birds fly!
If you want to move forward, you need to push backward—on the ground, on the water, or on the air. You want to do this efficiently, using as little energy as possible. In this show, we answer a bunch of questions:
Why can your dog run faster than you?
Why can adults walk faster thank kids?
What’s the best way to jump as high as you can?
What would it be like to swim in molasses?
Special thanks to 3rd grade students at Dunn Elementary who helped us make some videos for this episode!
