Science journal 5

science journal 4 (trebuchet and onager)
This week we did observed the trebuchet and onager, but we put in more weights in the trebuchet, and put the stick further down for the onager. We had to observe the difference between the two types of catapults. I noticed that the onager flew a lot higher than the trebuchet but it didn't go as far. I think that the onager goes higher than the trebuchet because it let goes sooner than the trebuchet. Another way I think the onager travels higher is because of the way it fires.
I think that the trebuchet fires further than the onager because it lets go later and it much bigger than  the onager we are experimenting on.
