Grade 3 ecosystems and food webs

Producers, consumers and decomposers, and how a change ripples through a food web. Here is what we have for Grade 3.

Lessons

Survival Clues: Fossils, Groups and Changing Habitats

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.
