Who eats who in the savannas of Africa? Explore trophic levels with part four of an eight-part series of lessons focused around Gorongosa National Park. After young explorers identify animals using trailcam images, they construct a food...

Explore the food chains that support Arctic ecosystems. A class discussion on interdependence and the different roles plants and animals play in ecosystems provides students with the knowledge to complete a worksheet asking them to...

In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

What better way to learn about ecosystems than by getting outside and observing them first hand? Accompanying a field trip to a local park or outdoor space, this series of collaborative activities engages children in...

Jorge is a cook in an underwater restaurant. He knows a lot about food webs. Dive in and learn about it with him.

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

A module that explains what an ecosystem is and how energy and matter move through them. Students will look at the different roles of plants and animals and at ecological relationships in food chains and food webs.

A comprehensive ecology learning module where students assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems.
