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.
Check out the photos below to see how grass has grown in the International Space Station and compare it with the grass that has grown in your Alien Head. What are the differences? Why do you think that grass grows differently on Earth than it does in the International Space Station?
Insert dirt or cedar shavings into the nylon and plant the seed
Tie the nylon shut
Water your Alien Head with the spray bottle
Water the Alien Head 1-2 times daily and watch the grass grow!
