On the 24th July, 2012, Room 3 went to Mr.Brown's class (Room 1) to learn science. We learnt about buoyancy. Every thing in the world has buoyancy. Buoyancy is if something can float. (A balloon has alot of buoyancy.) Then we learnt about density. If something is LESS dense than water, it will float. If it is MORE dense than water, it will sink. Things that are LESS dense than water are buoyant. Then, we tested some things. We learnt that paper, gluesticks, felts, containers, and plastic pencil cases are very buoyant.
