From Mystery Science: Food Chain Activity - free hands-on science activity for and grade elementary kids. Part of a complete unit on Ecosystems: Ecosystems & the Food Chain. Meets Common Core and NGSS.
I like that this is center based because it's different than the rest of my activities. This activity has cause and effect cards that focus on how changes in a food chain or food web can effect an ecosystem which is a part of our unit.
This is a great independent practice activity on food chains. Students could research a food chain and then display it on index cards. The students will draw each animal on an index card then attach them together in food chain order with string or yarn.
