MAKE
A CRATER
ONE
Collect
a few things.
- A bucket or tub of fine, dry
sand.
- A cup of fine, dry sand of
contrasting color.
- A flour sifter or salt
shaker.
- Projectiles: ball bearings,
marbles, lead fishing weights or something small and heavy.

TWO
Set up the bucket
- Shake the bucket or tub of
sand to level the sand.
- Put a light dusting of the
contrasting colored sand over the top of the sand in the bucket using
the salt shaker or sifter.
THREE
Finish
- Drop projectiles from
different heights and observe the craters they produce in the sand.
- Make note of the size and
weight of the projectile and the height from which it was dropped.
- Measure the width of the
craters from a point on the peak of the rim to a point on the rim on the
opposite side of the crater.
