This week in blast off we built catapults. We had to follow some instructions on how you build them. We made three models, One that is small, one with a triangle base and one with a square base. We had to indentify the energys that catapults hold, when it is launching it has elastic and potencial energy, when it is in the air it has kinetic energy.
Here are some slides on our recorded data and the instructions so you can build them too:
