Gummy Bear Launching

In this experiment we are trying to see whether there is a difference between launching the gummy bear on his back or on his bottom. In this experiment we used two factors the bear sitting on his bottom or the bear lying on his back. The level for this factor would be the bear sitting on his bottom and the bear lying on his back. For the second factor, we chose whether the chair worked better or without the chair. The level for this factor would be launching with the chair and launching without the chair. The four treatments that we came up with for our experiment were the bear sitting on his bottom with the chair, the bear sitting on his bottom without the chair, the bear lying on his back with the chair, and the bear lying on his back without the chair. When we tested which of the treatments worked better we had one person randomly pick from the four treatments, not knowing what order they went in on the sheet and started with that one and went through them all after that.

For collecting our data we had Alex stand in the same spot every time and he and only he shot the gummy bear. We counted by the number of tiles in the hallway and we used the tile that the bear stopped rolling or bouncing at. We had one person doing all of the counting so it was never a different method. Then once we got that number, we recorded it on our data table. Our data table was labeled with bottom with chair, bottom without chair, back with chair, and back without chair, and included 30 rounds, although we only got to 15 rounds per treatment.

We have concluded that the gummy bear went the furthest when it wasn’t using the chair. The gummy bear didn’t travel as far with the chair, this may be because it was really hard to situate the chair in the rubber band with the gummy bear sitting the right way and then shoot it the way it was supposed to be shot. We have also concluded that the gummy bear went further when it was sitting on its bottom rather than lying on its back. We think this may be because it was easier to hold and shoot if the gummy bear was vertical.
