Form 11’s Natural Selection


As part of their 'Reproduction and Inheritance' topic in Biology this term, Form 11 have been learning how to explain Darwin’s theory of evolution by natural selection. How best to demonstrate this … Skittles of course?! Thanks to Dr Carlin’s innovative teaching skills, our Form 11s pretended to be birds with different sized beaks (fingers, tongs, tweezers and straws) and tried to eat beetles (Skittles) from a variety of different environments to show how adaptations would cause some birds to be successful whilst others would starve and there characteristics would be lost from the local population. Conclusion: Those organisms best suited to their local environment survive best, breed and pass on their genetic information to the next generation. Who knew a packet of skittles could prove Darwin’s theory so clearly!
