Ecological Pyramids: Energy, Biomass, Numbers
Exploring the quantitative relationships of energy, biomass, and numbers at different trophic levels.
Key Questions
- Explain why there is always less energy available at the top of an ecological pyramid.
- Compare the structure of an energy pyramid to a biomass pyramid.
- Predict the effect on lower trophic levels if a population at a higher trophic level significantly increases.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
