No Prep Plans: Decomposers & Microorganisms (Nature Recycling Investigation)

No Prep Plans: Decomposers & Microorganisms
Research + Group Project (Nature Recycling Investigation)
Year 7 Biology | Aligns with Cambridge Lower Secondary Science

Bring decomposition to life with this engaging Year 7 biology investigation! In this hands-on Nature Recycling Investigation, students explore how decomposers and microorganisms recycle nutrients by observing real decomposition over time and conducting a structured scientific investigation.

Students investigate fungi, bacteria, detritivores, composting, nutrient cycling, and decomposition while designing a detailed lab report and scientific observation record.

Students Will:
• Explore the role of decomposers in ecosystems
• Investigate fungi, bacteria, and detritivores
• Observe decomposition over 1–3 weeks
• Compare how different materials break down
• Record scientific observations and data
• Design a detailed Nature Recycling Investigation report
• Connect decomposition to composting and climate science

What’s Included:
• Teacher direction page with lesson flow and safety guidance
• Two-page student lab report and recording packet
• Color and black-and-white versions
• Extension and early finisher ideas
• Online research resource suggestions

Concepts & Skills Covered:
• Decomposers
• Microorganisms
• Fungi and bacteria
• Detritivores
• Nutrient cycling
• Carbon cycle connections
• Composting
• Scientific investigations
• Variables and observations
• Scientific drawing and lab reporting

Perfect For:
• Year 7 Biology/US Grade 6
• Cambridge-aligned science classrooms
• Inquiry-based science learning
• STEM and collaborative projects
• Ecosystems and life science units
• Lab investigations and scientific observation practice
• Sub plans with meaningful academic engagement

Why Teachers Love This Resource:
• Hands-on investigation that students genuinely remember
• Combines biology, ecology, and environmental science
• Encourages real scientific observation and data collection
• Includes structured lab report supports for middle school learners
