Hey guys its Ryan.M, all we did in class on Friday was a momentum lab.

1. First we grabbed 2 marbles, a ramp, paper, and ink paper (the black one). [carbon paper]

2. TEST 1- Then we let the ball go off the ramp and fall down and land on the ink paper (which is over the white paper). We do each trial 6 times

3. TEST 2- After we set up the second ball in front of the ramp, we let the first ball crash into the second so that they go in opposite directions. We do each trial 6 times.

4. we take the two distances between the ramp and the landing spots of the second test. They should add up to the distance of the first test.

We didn't have time to finish the lab so we will be getting time to do it on Monday.
While half of the class was doing the lab the other half got two worksheets to work on. One was Impulse and Momentum and the other was a chapter 9 review.

I guess that's all so the scribe for Mondays class will be Niwatori-san.
