Explore how energy moves through living things with Grade 7 Photosynthesis and Cellular Respiration Worksheets. In this Energy Detectives learning station activity, students investigate how plants capture light energy, store it as chemical energy in sugar, and how organisms release energy from food to produce ATP inside cells.

🔬 Follow the Journey of Energy

Students explore the relationship between light energy, chemical energy, sugar storage, and ATP production. Rather than treating these processes as isolated facts, the resource focuses on how organisms transform and transfer energy through essential cellular processes.

Scientific thinking is also central to the activity. Students compare evidence from different scientific investigations to explain energy transfer and conservation in living things.

What Students Explore

• Identify how organisms transform light energy and chemical energy during processes inside cells.
• Explain how plants store captured energy in sugar.
• Describe how organisms release energy from food to produce ATP.
• Compare scientific evidence to explain energy transfer and conservation in living things.

What Is Included?

• Station recording sheet: Provides a place for students to record their investigation work.
• Station cards: Present the learning station activity for exploring the journey of energy.
• Station wrap-up: Provides a concluding task to bring the station learning together.
• Answer Key PDF: Includes the answers and an additional teacher guide.
• Teacher Guide: Includes learning objectives, teaching tips, discussion questions, and common mistakes to watch for.

How to Use This Science Activity

Use the learning stations during a Grade 7 life science unit on structures and processes in organisms. Students can work through the station cards, record their investigation responses, and complete the wrap-up to consolidate their thinking about energy transformations.

The included teacher guide supports lesson preparation and classroom discussion. Its teaching tips and common mistakes provide useful reference points when introducing the relationship between photosynthesis, energy storage, and ATP production.

Why This Resource Belongs in Your Life Science Unit

Energy transfer can be difficult for students to connect across different biological processes. This activity brings the journey together, helping students make connections between the energy plants capture, the chemical energy stored in sugar, and the energy organisms obtain from food. The evidence-comparison focus also gives students an opportunity to practise scientific reasoning rather than simply recall vocabulary.

For teachers covering MS-LS1-4 within the Grade 7 life science topic From Molecules to Organisms: Structures and Processes, this resource offers a focused way to explore energy transformations, cellular processes, and scientific evidence in the classroom.
