Budding scientists work collaboratively to reenact energy flow in a food chain. Scholars take on roles such as producer and consumer and perform tasks that symbolize energy flow in order to provide evidence of how much energy passes...

Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

Test scholars' knowledge of ecosystems with a 20-question pre-assessment. Assessment challenges learners to answer multiple choice questions, read diagrams, and complete charts.

Explore a variety of science concepts in an interactive textbook created for middle school scholars. A lengthy table of contents takes readers to pages comprised of a subject overview, outline, and summary. Follow links further to find...

Thirteen short-answer questions follow a brief food web activity in a formative assessment designed to test knowledge of ecosystems and the energy that flows through them.

Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

Gravity is just one consideration when determining human habitability on a new planet. The lesson connects four different units and starts with connecting the various systems: planetary systems, human body systems, etc. After scholars...

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

[Free Registration/Login may be required to access all resource tools.] When an herbivore eats a plant, the energy in the plant tissues is used by the herbivore. Every time energy is transferred from one organism to another, there is a...

[Free Registration/Login may be required to access all resource tools.] Energy must constantly flow through an ecosystem for the system to remain stable. What exactly does this mean? Essentially, it means that organisms must eat other...

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.

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...
