Science journal 4

19.6.17  Week 4
This week we have been learning about projectiles (such as trebuchet and onager). A trebuchet is a type of catapult that has weights at the end of it, and when you pull a string it flips and fires.
An onager is kind of like a trebuchet but it is a bit smaller and it has a smaller stick then a trebuchet.
