Build a Marine Food Web

Explore various ecosystems from around the world as your class discovers the interdependence of all living things. Using the provided sets of ecosystem cards, young scientists work in small groups building food webs to demonstrate the...

From bears and owls to chipmunks and trees, all life depends on the sun for the energy to survive. Young biologists develop an understanding of this big idea as they arrange this series of plant and animal picture cards into food...

It's all connected. Classes create a web to connect living things in a local ecosystem. They create cards with both living and nonliving things found in their areas while considering the characteristics of each. After they have a good...

Plants. We can't live without them! Bill Nye discusses how every living thing relies on plants using a concept called the food web. In a very visual demonstration, he ties a cord from one picture to another on a three-dimensional...

Young scientists weave together an understanding of ecosystems with this fun collaborative activity. Taking on the roles of different living and non-living elements of specific habitats, learners use a ball of yarn to create...

Rhinozilla is Mia's bearded dragon and the focus of this lesson on energy flow in an ecosystem. She uses him to explain the energy pyramid, from producers through third level consumers, and she likens the food chain to a video game. Mia...

Eager ecologists explore ecosystems through video and photographs of a Mangrove. They discuss the animals in this habitat and how they interact with each other after reading and discussing "The Sea, the Storm and the Mangrove Tangle."...

Fourth graders study about food chains. With the assistance of a local biologist, Students hike the school trail system. They explore ecosystem and collect data by charting the organisms found and identifying the energy source. They...

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...
