This week we have been learning about elastic potential energy and angles (degrees). One of the experiments was a slingshot rocket and from this we learnt how to make one and what design is better. I think popsicle sticks in a v shaped and a cut rubber band work together well because you have more elastic potential energy.
Another experiment was flipping frogs. In this all of the energy was in the elastic band. I think most of the experiment relied on the card because if the card bent the frog didn't work.
We also had another experiment and that is u called angle launcher how it works, you pick an angle. The best angle was 45’ degrees you can choose short, medium or long range and then fire
