Nice work!


 * CLAY! jello is overated.**



Instead of Jello we used a more solidified medium to more accurately gage the impact of the falling coins. This clay slab clearly displays that the dollar coins impact is much greater considering there is a deeper imprint in the clay, on the left, opposed to the penny imprint, on the right, which is shallower. To provide valid data we made sure to drop the coins in the same general region, seeing as the clay tends to think out and become brittle towards the edges. After a few drops we took the closest two and measured the deepest side of the imprints for both coins.The dollar resulted in being 2 millimeters deep while the penny was only 1 milimeter. Our evidence suggests that our hypothesis of the dollar coin being more dangerous considering its greater impact is correct.

Our evidence is inclusive considering judging from the Styrofoam indents the penny and coin dollar show no difference in impact. Further tests will need to be conducted. TIME TO BRING OUT THE JELLO. - Jello would have been a perfect gage for the impact, similar to the use of ballistics gel. We would have been able to see how the coin impacted and how deep it went. (That and it's delicious)

i do think that the jello would have been a cool idea because it would show how deep it would have gone since it is a less dense material than clay is and it would maybe show a more significant difference than the clay.
 * 1) __DROPPING TO SEE WHICH ONE HITS HARDER__
 * Will you be dropping them onto styrofoam or something else?
 *  We will be using either styrofoam or jello in a clear container to gage the impact of the coins once dropped.
 * What height will you be dropping from?
 * The stairwell which is four meters.
 * Will you be able to hit the styrofoam (or whatever you're dropping them onto) from that height?
 * Attempt to accurately drop each coin at different times over the jello or styrofoam to ensure that it hits it.
 * How will you know which one hit harder?
 * The indentation marks in the styrofoam will show which one hits harder and the depth of the coin in the jello will display which coin hits harder.

We think that the dollar coin is more dangerous! because its terminal velocity is greater considering its weight is greater than that of the penny. Though the surface area is also greater for the dollar coin, proportionally it is still going to have a harder impact considering the weight affects its terminal velocity more than its surface area in comparison to the penny.

I think that we exceeded because we used the clay. We brought another element to this project=]
