December Science Challenge
Get involved in our December Science Challenge - How are craters formed.
- Shallow tray (e.g. a baking tray)
- White flour
- Drinking chocolate
- Marbles and/or small balls
- Fill the tray with approximately 2cm of flour and lightly sprinkle some drinking chocolate to cover the entire surface of the flour.
- Drop the marbles/balls (asteroids) into the tray from the same height.
- Make craters using different sized marbles/balls.
What happens when you drop the marbles/balls from different heights? You could record the size of each crater in a table. What happens to the white flour when you drop the marbles/balls? Try with different sizes and weights of balls to see if the craters are deeper or different shapes.
A crater is a bowl-shaped depression formed by the impact of a meteorite, volcanic activity or an explosion. The oldest and largest impact crater on Earth is the Vredefort crater in South Africa. It is estimated to have originally been 185 miles (300 kilometres) across. A huge meteorite or asteroid created this giant crater 2.02 billion years ago!
Please send in photos of your work via Google classroom or the office email address office@valence primaryschool.com.
