Make a Crater!

Students will be building their very own crater and testing different sized balls from various heights to see how their crater size may differ.

What You Need

Materials needed per student:

  • 2 baking dishes
  • 8 cups of flour
  • 1/4 cup of cocoa powder
  • Measuring tape
  • 3 balls of different sizes. e.g.: marbles, golf balls, baseballs

Instructions:

What To Do

How to make a crater:

  1. Distribute the flour between two pans.
  2. Add a thin layer of cocoa powder on top of each.
  3. Place the pans on the floor.

Pan A:

Drop the three different balls from a height of 1 m. Compare the sizes of the resulting craters!

Pan B: 

Drop the medium ball into the pan from a height of 0.5m, 1m, and 1.5m. Compare the sizes of the resulting craters!

Discovery

What's Happening?

This activity provides students with the background knowledge on what a crater is, how they form and how Earth can be effected upon their impact.

Craters are pits that are caused by an impact! Craters exist on the Earth, on the Moon, and on other planetary bodies, and are caused by a high-speed collision between something small like an asteroid with something large like a planet!
