What living and nonliving things can be found in the San Elijo Lagoon ecosystem? Student scientists will develop critical scientific skills, including observing, recording data, and making claims, as they hike around this exciting ecosystem. Students will identify key interactions within the ecosystem – with a special focus on decomposers, cycling of matter, and human activity.

The complete Ecosystems in Action learning unit is aligned to NGSS: 5-LS2-1, 5-ESS3-1, 3-5-ETS1-2.
