Expert response from Jennifer Heldmann:
These are very impressive drawings!  Each one has a variation of a spaceship and/or grenade.  Very creative designs with the spaceships!  For your next round of designs, try to think of an experiment that you could do in your classroom to try and determine the effects of different angles on the amount of ejecta that gets kicked up during an impact.  You'll have to think of a good type of impactor, a way to measure the angle, a way to measure the amount of ejecta, and decide on what type of material you want to impact into!  Also when thinking of your designs, always remember safety first!
