Floating and Sinking

In Week 2, the Science Club experimented with floating and sinking.  We investigated with all sorts of things you can find in the classroom to see if they would float or sink.  We worked in pairs so that one person could record our data, so that we could then compare it to our predictions.  The most surprising thing was that some things floated for a short while, but then sank when they became water logged, like cotton wool balls.
