[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.)
