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.

• Why do some animals live in groups? 45–60 min

  Teams read data cards on wolves, meerkats, sardines, honeybees, emperor penguins and a tiger, then play a predator game to test whether a group spots danger sooner than an animal alone. They argue with evidence how living in a group helps some animals survive, and what it costs them.
