Primary 4\/5 became scientists for the afternoon. \u00a0We were experimenting with an orange and a grape to see if they would float or sink.<\/p>\n

A lot of us thought the orange would sink because it was heavier than the grape. \u00a0Imagine our surprise when our experiment showed it was the other way round.<\/p>\n

Mrs Haigh (Emma’s mum) spoke to us about density and why the orange floats even though it’s heavier. \u00a0Did you know that the orange peel contains little air pockets that make it less dense than water? \u00a0This is why it floats.<\/p>\n

We tested this theory by peeling the orange…it sank!<\/p>\n
