Weaving the 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...

Entangle your life science class in learning with this collaborative food web activity. Using pictures of the plants and animals native to a particular ecosystem, young biologists work in small groups to construct visual...

Here is an extremely simplistic look at food chains and webs. It depicts three different food chains, each containing a plant, plant eater, and meat-eater. Learners fill in the missing part of each chain by using the images provided at...

As part of a study of food chains and food webs, class members complete a series of worksheets that trace a marine chain from producers to consumers or decomposers. After studying a food chain example, young marine biologists make up...

You are what you eat—or at least a part of what you eat. Budding scientists examine owl pellets to develop their own food webs. They use tooth and skull identification techniques to classify what they find.

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...

Students discuss ecosystems, eliciting their current knowledge of an ecosystem. Students receive an Ecosystems document and look at the picture. Students brainstorm connection between the cover picture and ecosystems. The indicated...

Rhinozilla is back to take your lesson plan on trophic levels a step higher! After showing the video on food chains (available through the See All Related Jams button), add to it by showing this one. It deals with omnivores and 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 young scholars with the knowledge to complete a worksheet asking them to...
