• The Camouflage Game

    The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. How can we get kids to understand this interesting phenomenon? Let them be the birds who will catch these moths. Then they will see in action how camouflage helps an animal to protect itself.

    In this example, children see two kinds of mice in the sand - brown mice stand out, while white mice are almost integrated with the environment. Who should I catch? A child picks up the inflatable hammer on the ground, turns into a predator and attacks the target. Finally, he will find that the proportion of brown mice is significantly reduced, while white mice survive in large numbers, which is the secret to camouflage.
