Energy Flow in Ecosystems
Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

How Does Your Ecosystem Grow?
Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Two Way Causality in Ecosystems
Young scholars complete various activities in order to explain that ecosystems are complex and that animal behavior (mainly that of a predator) is not necessarily intentional or bad.
Curated OER
Producers and Energy Transfer
Fifth graders discuss the relationship between producers, consumers, and decomposers as they look at the energy pyramid. While working in small groups, they create an ecosystem that includes all or some of the given categories, and they...
