We think that the dollar coin would be more dangerous than the penny because it has more weight, and almost the same surface area as the penny.

Good work! The dollar coin won - interesting. I'm anxious to see the video when I get back on Thursday.

MONDAY: We think that the dollar coin would be more dangerous because it would have more of a terminal velocity because it has more mass and would move faster. In our experiment we will drop the coins from a chip clip and we will film the landing area to see what hit the ground first, then we would film again so we could see the whole drop and see if they go at different speeds. We would like to drop the coins from the highest height possible, so we would go to the stair well, and drop them onto something soft and that has a lot of cushion, like styrofoam. We will know which one ht harder because it would leave a larger or more in depth imprint. In order to get the surface area and weight of the coins, we could use wikipedia or weighand measure them ourselves.

Tuesday: We will film the landing area to see which coin hits the ground first.

Measurements: Dollar Coin mass- 8.10 g diameter- 26.5 mm

Penny mass- 2.5 g diameter- 19 mm http://hypertextbook.com/facts/2002/MillicentOkereke.shtml wikipedia.com

THE DROP! We filmed the drop and it seems to be that the dollar coin hit the ground first.

Wednesday: FINAL CONCLUSION- We believe that the dollar coin is more dangerous because it has more mass and gains speed quicker than the penny does.

We compared our results with Danielle and Felicia's experiment and our results are the total opposite of theirs'. Also, we looked at Elizabeth & Ashley's page and they did the impact experiment. If we were to do that experiment, We think that the dollar coin would have more impact also.
