Why is there junk in space? | Teach with space PR51
In brief
Do you want to learn how Space Debris is generated? In this classroom resource, we will use marbles as satellites populating orbits around Earth. By throwing marbles into each orbit scenario, we will learn how the principle of the Kessler Effect works. Are space debris more often as big as a school bus, or a small as a marble? In this resource we will also learn how many big or small debris are orbiting the Earth, by simulating a debris collision using crisps and measuring the resulting pieces sizes!
