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.
Whalen's Classroom - Food Chains When learning about food chains, students often times forget the order of the chain. This quick poster helps them remember what type of animals are within the different levels of the food chain.
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.
