Use this TED Ed lesson, complete with video, questions, and links to resources for deeper understanding, to introduce the food chain.

Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems. When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem...

Lesson plan to construct and explain a food chain. Includes games and activities to teach and reinforce concepts.

A very informative site that discusses food chains and webs in detail. Not too complicated and fairly easy to understand, it also includes some pictures.

Did you know that 80% of the fish we eat comes from the ocean? Since oceans cover so much of the earth you would think that we would never be in danger of running out of its resources. Learn how overfishing is causing many problems with...

Work samples, phenomena, assessment templates, and videos that directly address standard 5-PS3-1: food energy from the sun.

This Museum of Science page does an excellent job of explaining the importance of plants as producers in the sea. The food chain or food web has to start with the plants.

Stimulate and challenge your ESL students with a unit on Polar regions. Students will use higher level thinking skills while learning about animals, habitats and food chains. You will find many downloadable pages.

Learn how energy is transferred along a food chain.

Learn about the characteristics of and different species of phytoplankton. Topics highlighted in this article include photosynthesis, global change, and the marine food chain.

During this lesson, students will visit Internet sites to research facts about owls and food chains. They will use this information to complete a picture of an owl food chain, dissect owl pellets, and write a class book about owls.
