[this is school]

Yesterday, we did this lab where we were able to track our motion with a motion detector and it would show up as data on a graph. It was a really cool lab and I really enjoyed it. My group, Hannah, T-mike, and I, didn't finish but we still got a lot of info. We started out just moving backwards slowly and seeing how jagged the line was. Then we tried moving backwards quickly and compared the two lines on the graph to see the differences. We also did the same when we did one line where we walked-paused- and then ran. and compared it to the next line where we had to make the smoothest possible line.. and then compare the lines. I was surprised how different our motion looked on a graph. I kinda wonder if the motion detector can see how our muscles move and how we switch our weight or muscles we use when we move... (hmm.)

If I were to play golf on the moon, there would be less gravity so it would be lighter, easier to hit, and would definitely go farther. But according to inertia, it might not stop, an object in motion, stays in motion. The golf ball would also be lighter and in that case, might be easier to stop as well.

For my Bernoulli's Law demo, I used two(2) pieces of paper and held them about 2 inches apart. Then, I blew into the middle area between the pieces of paper and the papers almost touched... and right after, the papers touched. I also had another idea that I tried and didn't work, but could work with something lighter. I tried putting two golf balls about an inch apart on a table and blowing in between. I think it would work better if I used something lighter like a ping-pong ball. If it worked, you're supposed to blow into the middle between the balls and then the balls will come together and touch!
