I think that the dollar coin will fall faster, we think this because even though the surface area of the dollar coin is larger, the weight is larger also so it will fall faster and with more force.

Makes sense. Did you get any pics of the indentations in the styrofoam? (It's not a big deal if you didn't.)

We are going to drop both to see which one hits harder, we will drop the coins on styrofoam from the stairwell and will measure the impact with the styrofoam.

We ran into a few problems when dropping the coins, it took a few tries to it the styrofoam block when we dropped the coins, but once we did it proved that the dollar coin falls harder because it left a much deeper indent in the block.

In conclusion, the dollar coin is more dangerous then the penny when dropped because when dropped onto the styrofoam, the dollar coin put more of a dent. There was a big dent when the dollar coin was dropped, and with the penny, it wasn't as big.
