Science journals 3&4

In week 3
I was at zones, but my class used wool instead of fishing line wire. I predicted that it wouldn't go as far because there is more friction to slow it down. I wonder if the wind would slow it down?

Week 4
We did the trebuchet first. We used two weights and it went 8 meters and the last one we used all the weights and it went 38 meters. Then we used the onager and the first one it went 21.41 and on hole four it went 37 meters. I think the trebuchet goes further because it goes higher so it has more time in the air. The onager goes lower so there's more friction when it touches the ground it slows it down. My learning is at multistructural.
