i think the dollar coin is going to be more dangerous.

I'm glad the video worked. Wow - I didn't expect the penny to win! I'm anxious to see the video when I get back on Thursday.

> For the project we will be doing this.
 * 1) __DROPPING TO SEE WHICH FALLS FASTER__
 * Will you be using the chip clip to drop them at the same time? Yes we will be using the clip clip to drop them so we can get the accurate falling time.
 * How will you know which one hit first? We will know which one hit the floor the fastest by which one actually hits the floor the first.
 * If you are filming it, will you film the entire drop or just the spot where they land? We will film the entire drop because them you will know which one hit the floor first.

2-10-09__DROPPING TO SEE WHICH FALLS FASTER__ Today we went out in the stair well and dropped the penny and the dollar coin. However we ran into some problems we had trouble recording it because the coins were falling to fast, but we found out that the penny was the first one to fall in the video we recorded.
 * Chip clips are on the side counter if you need them
 * Pennies and dollar coins are on the teacher desk
 * Only one group at a time in the stairwell
 * Be quiet in the stairwell; if the sub reports that your group was noisy in the stairwell, your group will receive an automatic grade of "redo"
 * Update the group page to tell me what you found, or to explain problems you ran into

2-11-09 ALL GROUPS > For my conclusion of the penny and dollar coin theory i think the penny hit the ground first and the dollar coin came right after. We had trouble getting both the coins to drop on the stierfoam they kept on dropping apart from one another. Other groups said they had the same problem we did, also the other groups they agreed that the penny hit the ground first and then shortly after came the dollar coin. But however i'm kind of leaning towards the dollar coin being the mot dangerous because after all it is the heaviest and the penny has less mass therefore i think the dollar coin will be more dangerous.
 * 1) ** Do any final research or testing.
 * Remember what I said about being in the stairwells
 * Update the group page to tell me what you found
 * Put down your final conclusion - is the dollar coin as dangerous, more dangerous, or less dangerous that the penny?
