We believe that the dollar coin is more dangerous than the penny because it has a greater surface area and the mass is heavier.

Interesting. I'd really to see the video when I get back on Thursday.

**Feb. 9th:**

We will be doing #1 and will be using the chip clip to drop them at the same time. We will know which one hits first because one of us will be standing at the bottom and will be able to see which one hits first. We will only be filming when they are about to hit the ground to make sure we catch which one actually does.

Feb. 10th:

We dropped both coins at the same time with the chip clip and it was kind of difficult at first because the little chip clips do not work as well so we had to do it another time with the bigger one and realized that both coins hit at the same time.

Feb. 11th:

We believe that although they hit the ground at the same time, the dollar coin is more dangerous because it has more mass and a larger surface area.

Compared to what everyone else found, everyone else dropped the coins to see which made a bigger indentation in the styrofoam and they realized that the dollar coin would do more damage. Although ours hit at the same time, we knew that the dollar coin would definitely do more damage because of its larger surface area.
