Webbing the Food Chain

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...

Throughout history, the growth of big cities has resulted in the destruction of ecosystems. In the case of Chicago, IL, a grassland that was once home to bison, deer, wolves, and foxes quickly became a booming city of over three million...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

Transform young biologists into grasshoppers, lizards, and hawks as you teach them about food chains in an interactive life science simulation. Working collaboratively to act out three different scenarios involving...

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...

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

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...

Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

The coral reef ecosystem is abundant and lively. Dive in for an underwater view of the species living there. Polyps, urchin, barracudas, and eels (among others) exist in part because of the sun's presence in this ecosystem. Use this as...
