Science in Year 4 this week was looking at forces again. We were making and testing catapults. We got put into groups of 2 or 3 and we were assigned to create a catapult and see how far a cotton ball would go. Before making the catapult we got the Investigation planner that we had to fill in.
Looking at the variables (‘what changes and what stays the same and making predictions like ‘ how far do you think it would go?’
The catapults were made of rubber bands and paddle pop sticks. We tested our catapults in the hall and we had to see how far the cotton ball would go.
