Survival Clues: Fossils, Groups and Changing Habitats Grade 3

Four no-materials lessons on what helps living things survive: reading fossil cards from Antarctica to the Himalaya to work out what places were like long ago, a predator-and-prey game on why animals live in groups, a camouflage hunt on printed bark and sand, and case files on what happens when a habitat changes. Everything runs on printed sheets.

• What happens when a habitat changes? 45–60 min

  Teams rotate through four case files (a pond that dries up, a forest cut down, cane toads arriving in Australia and a river that is dammed) and sort who survives, who moves and who dies. Then they judge solutions for a new highway through a forest, using evidence from wildlife bridges in Canada and the Netherlands.
