At Home with the Mad Scientist: K-2 for March 2009

Making Craters

Remember: Always have an adult help you with any experiment.

Materials

  1. A small baking tray
  2. Some flour
  3. A stone or marble

Procedure

  1. Pour the flour in the baking tray and spread out evenly with your hand (about an inch deep).
  2. Drop the marble or stone in the flour.
  3. Carefully remove the marble/stone from the flour.
  4. Look at the crater the marble/stone has made.
  5. Repeat steps 2 and 3 a few times so that you can see several craters.

What's Going On?

Meteorites are huge rocks that crashed into the Earth and Moon at high speeds a long time ago. When these rocks hit they made dents of round hollows called craters. The force of impact pushed some of the rock outwards to form a ring of mountains.

Can you see the craters that have been made on the Moon? Take a pair of binoculars and look at the Moon in the evening. These craters are scars from space rocks that have crashed into the surface long ago. Also, a few craters made from meteorites on Earth have formed into crater lakes.
