catapults

hey it's Mia today in my class we made catapults using  materials that we thought would work such as rubber bands,10cm spoon,a plank of wood and some nails. mine went far and some of mine didn't we used stuff like stones and beads to catapult into the air we tried for times with each object then we had to measure and see how far it went then we had to write it into our book. and this is what i got the graphs of what i got.
