September 18 (Tuesday) Sonic Ranger Day 2
If you were gone today:
The Einstein Board
1. Students crossed their picture off and their partners picture off if they have all four lab partners for Graph Your Route take home lab due next Tuesday.
2. Students decorated our back bulletin board wi
Our classroom 2340 actually did the sonic ranger activity today. You do not need to make up this activity as we will leave an * on your grade. If we find time to place a video below, you may wish to watch the video to get an idea of what we were doing.
Basically, a motion/time graph would show up on the screen and we would have to match what we saw by holding a white board in front of a motion detector that would draw our motion as we moved. The partner would click the COLLECT DATA green tab when we were ready to go. Usually students would try it two or three times each and draw their best on the paper provided below.

The Sonic Ranger Handout
On the back of the Sonic Ranger, I challenged students to match the top graphs on the blank screen (a file) then attempt to draw the corresponding vel/time and acc/time graphs.

The Big Pictures:
1). Velocity/time graphs are tougher to match than the distance/time graphs because it is hard to keep a constant speed and to do a smooth acceleration without jerking the white board.
2). In the distance/time graph the line went up as you went further away and horizontal whenever you stopped and went down as you approached it.
