Learners identify various animals and their habitats, as well as their specific traits In this animal habitat lesson, students list animals they've seen in their backyard. Learners select one animal and do research. Students then answer...

Young scholars understand what physical adaptations are and how they help an animal to survive. In this adaptations lesson, students research four animals and then make an original animal that has adaptations to make them survive.

Young scholars create a collage. For this animal classification lesson, students discuss why and how scientists classify animals. Young scholars view pictures of different animals and decide which class each animal belongs to. Students...

[Free Registration/Login may be required to access all resource tools.] Understand how energy flows within ecosystems through the use of energy pyramids.

Explore the different ecological roles of organisms in the ecosystem, and find out how the energy flows through them.

The following is a tutorial of food chains, food webs and food pyramids.

In this unit young scholars explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the...

A colorful tutorial about ecological pyramids. Read the information, and then check your understanding with some questions and answers about the topic.

[Free Registration/Login Required] In this interactive you will need to design a food chain that corresponds with the correct ecosystem. You will need a sign-in to access the media but it will be well worth your time!

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

This module offers an in depth study of the fundamental components of ecosystems. Activities include mini-lessons with videos and student assignments.

This illustrated guide to food chains and ecological pyramids will help clarify how energy flows through an ecosystem.

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.

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

Students learn about the feeding relationships in an estuary ecosystem with this interactive energy pyramid activity. A second activity involves research and a video clip to elaborate the learning.

Understand how organisms acquire energy and how that energy is passed from one organism to another through food webs and their constituent food chains.

For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

Learners analyze food chains, webs, and pyramids to determine how energy flows and matter cycles through ecosystems.

A video and a short multiple-choice quiz on food chains that explains how energy flows through the chain, beginning with plants.

Students will use a card sorting activity to construct a food chain and identify the role of organisms within that chain. The cards represent different individuals in an ecosystem and will help students begin to understand the concepts...

[Free Registration/Login may be required to access all resource tools.] Understand what trophic levels are and identify producers and consumers in a food web.

Describes how a food chain works in a desert and how the Mojave desert food chain works in particular.

Explains the processes by which energy flows through an ecosystem. Covers the meanings of key vocabulary, e.g., types of producers and consumers, trophic levels, food webs, and the energy pyramid.
