Science week 5

Week 5
 This week we did the trebuchet and the onager which both are a types of catapults. we had to observe the difference  between the two catapults.  I noticed that the trebuchet goes alot further. I think it's because it has lots of weights so it can go alot further, then there's  the onager, the things I noticed about the onager is that it goes alot faster. I think it's because it has a longer arm.
