Nice work; you exceeded my expectations, in spite of the wacky pictures.

Wednesday: We decided to compare our result to the infamous Mythbusters, Jamie and Adam. In our research, we learned that the mass of the dollar coin was 5.6 grams more than the penny. Also, with a sizable difference in thickness diameter, the dollar coin would be more aerodynamic than the penny. The Mythbusters reported that "a penny's terminal velocity is too low and it's mass is too small for it to penetrate human skin". Since the dollar coin is substantially different, it should do at least //some// damage, but as of the extent, we are unsure of. Through our demonstration yesterday, the styrofoam showed the velocity of the dollar coin would result in a bigger indentation on the foam, however styrofoam is unique from human skin. As we looked though our classmates pages we did not find many results to look over, so we decided to look at other classes work. Looking at John, Amanda, and Steve's Wiki (found in period 2), they did the same experiment as we had done, and had difficulties hitting the styrofoam with the coins. Comparing our demonstration and results with Katrice and Katie (found in period 9, college prep) they found similar results in that the dollar coin makes a larger impression in the foam than the penny.

ps- We're magicians ;)....couldn't resist

Nice work! I see you figured out how to upload images. You two are wizards! Just be aware that there's a space limit on a wikispace - don't fill it up.

Tuesday: We took a large piece of styrofoam, a chip clip, one penny and one dollar coin. We dropped it from the stairwell at 4 meters of height. Having better success than we perceived hit the target with few attempts. The dollar coin hit first and then we had to redo the penny by itself, hitting right after. The dollar coin had a fairly hard hit and did make a deeper impression than the penny did, as we expected. As we predicted, the dollar coin did more damage to the styrofoam because of it's greater weight, thickness, and mass than the penny.

Monday: We are going to determine which coin would have the most impact when dropped form 4 meters of height. The coins will be dropped from the stairwell at the end of the hallway...uuhhh.....as usual. :D Since the piece of styrofoam is not very large, there is a chance we will not be able to hit it the first few attempts. There is also the chance of having one coin hit while the other misses. To measure the impact, we will observe the depth of the impression made by the impact.
