Focusing on concepts from Jody Jensen Shaffer and Christopher Silas Neal’s award-winning CREEP, LEAP, CRUNCH! A FOOD CHAIN STORY, this STEAM unit explores interdependence within ecosystems through:

• Living food webs

• Energy ripple math

• Rube Goldberg-style chain reactions (this was a favorite!)

• Real-world ecosystem challenges & solutions

• A creative diorama to bring it all together

This unit is designed for students in grades 3–5 and is structured over the course of 10 lessons.
