Science journal week 3

Week 3: Drag
When  we taped paper to the front of the balloss”. It didn't go very fast in fact it didn't move at all because the paper stopped it for some reason I didn't know, so those are my observations for week 3 science term drag.
on it didn't move at all.
I think it didn't move because there was too much weight. The sound was quite funny it went like something this “Frrrnbhnumffffs.”
Week 4: Trebuchet
This week we experimented with a trebuchet,  I noticed that there was no obvious mathematical pattern in the measurements. I think it was like that because of how hard the person pulled, wind speed and direction and also how many weights there are. I also noticed that the heavier ball went half as far as the tennis ball.  I wonder what should happen if we tried to use two tennis balls. This week I think my gathering data was multistructural
and I think my inferenceing was multistructural as well.
