Show how craters are formed using stones, marbles or balls as meteorites
Various sized objects such as stones, marbles, balls. (you could also try finding objects that are the same size but differ in density
1. Fill the tray with the sand, you can make it as deep or shallow as you like.
2. drop the objects into the sand to evaluate how craters are formed
3. experiment further by changing factors such as the density or size of the object, the amount of sand in the tray; you could even add water to the sand (although fresh sand may be needed after)
4. get your scouts to analyse how different factors create different sized craters
(please note - when changing the different factors of the experiment you will need to keep one factor the same throughout to ensure a fair test. Such as not changing the amount of sand used etc.)
