Concepts to teach: Food webs, different ecosystems
Goals: Students will learn about ecological relationships by constructing a simple food chain or food web.
- Describe the difference between various roles in the food chain.
- Display the connections between various creatures in the food chain.
- Demonstrate the effects of outside influences on food chains and ecosystems.
Activity Links and Resources:

- Food Chain descriptions and games
- Who’s Hungry? – Students use body movement and pantomime to simulate the feeding motions of freshwater organisms and demonstrate the interconnectedness of a food web.
- Food Chain Quiz—This is a good review of concepts in a fun format from the BBC.
- Food Chain Game—An interactive animated drag and drop game from sheppardsoftware.com
- Food Web Interactive from eduweb.com—Describes components of pond food chain and webs, and finishes with an experiment to see what happens changes are made to complex food webs.
- Students look at multiple food chains or webs from different ecological systems and talk about the relationships depicted.
