A Science Experiment

We are doing a new unit on balancing and weighing. The teachers have set up a mini sciance lab in the  spanish  room. We did our first lessons today. We had to work with a fulcrum, beam, and  unifix cubes  and we had to make it balance.  Another thing we had to was to balance a paper butterfly on an unsharpend pencil. We put 2 unifix cubes on one side and 8 unifix cubes on the other side. We made it balance by moving the fulcrum to the heavier side of the beam. We also put 10 unifix cubes on one side and 0 cubes on the other side. We did the same thing and made it balance.
