Extreme weather makeovers This primary resource helps children to think about the effect of the weather and change of seasons on the creatures that live in extreme weather environments. Discover how the weather changes the look of some animals. What changes does the change in weather ignite in the animals mentioned?

Many of the things that impress us most in nature are thought to be adaptations.
