MARSHMALLOW PEG CATAPULTS

Room 9 have been busy little bees making  peg  catapults and firing marshmallows. First we had to take a guess if the super pegs or the power pegs would go further.

We made a catapult by gluing the peg and the wood together. We glued the little block of wood on top of it. Then we glued the iceblock stick on top of it. And the milk bottle top on top of that. 

We loaded them up with marshmallows and fired them. Our

 partners measured them to see how far they would go.

They did it two groups at a time. We found out that super pegs went further than the power pegs because they had a tighter, stronger spring in them. Arlo and Davey's catapult went the furtherest.  Me and Amelia got 1 metre something, and me and Izzy got 2 metres something as our shortest shot. The best bit was eating them after we fired them!  By Asha and Lily
