The Role of Decomposers
Students will investigate the role of decomposers (e.g., worms, fungi, bacteria) in breaking down dead organic matter and enriching soil.
Key Questions
- Explain the importance of decomposers in a healthy ecosystem.
- Predict what would happen to the Earth if there were no decomposers.
- Analyze how decomposers contribute to the nutrient cycle in soil.

Planning templates for Science
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.
