Science KS1/KS2: Why do animals and plants have camouflage?
Michaela Strachan observes a variety of fish and how they have evolved to become better camouflaged to suit their environment.
Animals that are not well camouflaged are more likely to be eaten as prey.
Mutations are changes in genes that produce a beneficial or harmful trait.
After many generations the better camouflaged offspring will thrive and reproduce more.
Michaela models selection pressure by predators with a game involving sweets and salad.
This clip is from the series Evolutionwatch.
This could be used before a visit to an aquarium.
Replicate the game using sweets and salad or with pieces of coloured wool on the grass.
Pupils can make camouflaged masks or camouflage themselves against different backgrounds.
Pupils can also design an animal that is camouflaged against a given habitat.
They could enhance the learning by looking at pictures of animals that are camouflaged (grasshoppers, otters, toads, polar bear, tiger, cuttle fish, frog, owls).
This clip will be relevant for teaching Primary Science at KS1/KS2,1st level/2nd level particularly on the topic of animals and evolution.
