Bird Beak Investigation

All of the class took part in a bird beak investigation to see the effects of natural selection. They were each given either a cocktail stick, a peg, a bulldog clip or a pair of tweezers to use as their 'beak'. They then had 30seconds to feed using their beak. Different food sources provided different amounts of calories. After 30seconds, the children then had to work out how many calories they had eaten and then had to work out if they had died, survived or reproduced. After completing the game over a few generations, the children were able to work out which beak was best suited to 'Clippy Island' and which bird beak would have evolved.
