Here’s an easy experiment you can do to see the differences in how plants grow on Earth compared to how they grow in microgravity on the International Space Station. In this experiment, you will make your own “Alien Head” and watch it grow. Then, you can compare its growth to that of grass on the International Space Station.
Do you know why things float in space? It might not be why you think! In this activity you can make your own MixStix to see how density and gravity works on Earth and compare it to how it works on the International Space Station.
If you’ve ever poured out a cup of water, wrung out a towel, or sprayed something with a hose, you’ve observed how water acts here on Earth. However, what do you think happens when you wring out a wet towel on the International Space Station?
In this quick, easy activity, you can compare what happens when you wring out a towel soaked on water on Earth with what happens in space.
Have you ever taken a ride on a spinning amusement park ride? Maybe you’ve watched clothes spin in the dryer or seen track and field athletes compete in the hammer throw. All of these demonstrate the impact of centrifugal force.
It’s common misperception that everything is floating on the International Space Station because there’s no gravity. This is a myth! Astronauts float on the ISS because they are falling around the Earth at the same rate as the ISS, and this is what causes the state of microgravity.
Using simple materials, you can observe microgravity and demonstrate it to your students.
