Make Your Own Crater!

This is actually a neat experiment you can do outside and your parents won’t mind! In fact, they will want to help you with this fun experiment;)

 

You will need:

  • Mixing Bowl
  • Baking Pan
  • Flour
  • Water
  • Several round objects of different sizes (BB, Marble, Golf Ball, etc.)

You will:

  1. Mix the flour and water in the bowl until it has a soft consistency. (Caution: Don’t make it runny.)
  2. Fill the baking pan carefully with the mixture.
  3. Place the pan on a hard surface (Like the ground).
  4. Standing above the pan, drop your round objects into the mixture from different heights.
  5. Carefully remove each one. Smooth the surface and try another object!
  6. Try dropping heavier objects from a lower position and smaller objects from a higher position. Change them around.

STEM Challenge: Write the answers to these questions in the comments below.

a) Which objects make the biggest craters?

b) Did how far the object dropped make any difference?
