Catapults
I am going to talk about the stuff we have been doing in science with catapults. We have been changing a lot of variables. We only change only one variable at a time so we can have a controled experiment. The variables we have been changing are, angle of release, length of flipper, and size of foil ball. We are measuring how high and far our foil ball goes. We are in groups of three. We are also flinging little corks with our catapults. That is how my class is learning about catapults.
