Energy Flow in Ecosystems Lab – Food Webs, Ecology, Environmental Science

If your students struggle to really see how energy moves through ecosystems, this lab makes it click.

In this hands-on Energy Flow in Ecosystems Lab, students start by analyzing multiple food chains, then use that information to build a detailed, color-coded food web. From there, they apply the 10% rule, explore energy pyramids, and answer higher-level questions about ecosystem stability, human impact, and what happens when one part of the system changes.

It’s structured, but still gives students the space to think, connect ideas, and actually understand how everything in an ecosystem is linked.

Why Teachers Love This Lab:

• Visual & Hands-On – Students don’t just read about food webs, they build them, which makes the learning stick
• Builds Real Understanding – Moves beyond definitions into patterns, connections, and systems thinking
• Clear Progression – Students go from simple food chains → complex food webs → energy transfer
• Meaningful Application – Ties directly into real-world ecosystem stability and human impact

What’s Inside?

• Student Lab – Step-by-step activity guiding students through food chain analysis, food web construction, and energy flow
• Instructor Answer Key – Clear, thorough answers to support grading and discussion
• Comprehensive Teacher Guide – Includes pacing, setup tips, differentiation strategies, common misconceptions, and instructional insight to make implementation smooth and effective

This is one of those labs where students stop guessing and start seeing the patterns—and once they do, everything about ecosystems makes more sense.
