In week four we did catapult. I observed that the more you put in the catapult the ball went further. I wonder why this made it go further? Something else I noticed is that we put a hockey ball in and it didn't go as far. I wonder why this happened? I also wonder why the string is very easy to pull science there are so many waits in the catapult. I think my data gathering is relational because I have told you my wonders .
