Energy Transfers: Stores and Shifts
Year 10 Science Understanding how energy moves and changes in systems 60 minute lesson
Learning Objectives & Safety
WALT: Identify different ways energy is stored in systems WALT: Observe and describe how energy shifts between stores WALT: Recognise energy as a quality that is never 'used up' WALT: Distinguish between wanted and unwanted energy outputs Safety: Handle all equipment carefully, follow lab procedures
Brainstorm: Energy Stores
What are different ways energy can be stored? We'll compile a class list together Remember: energy is stored, not created!
The Eight Energy Stores
Chemical - stored in bonds (fuel + oxygen) Kinetic - energy of motion Gravitational Potential - height in gravity field Elastic - stretched or compressed objects Nuclear - stored in atomic nuclei Magnetic - magnetic field energy Electrostatic - separated electric charges Electromagnetic - light, heat, radiation
Key Concept
Energy is not a substance that gets 'used up' - it shifts from one store to another When one store empties, another fills Energy transfers, but the total amount stays the same
Energy Circus: 10 Practical Stations
Station Instructions
Work in groups of 3 students Spend 3-4 minutes at each station Observe what happens when you operate the device Identify: Input energy store → Output energy stores Record wanted vs unwanted outputs Move clockwise to next station when signaled
Energy Circus Practical
35 minutes of hands-on investigation Complete your observation table for all 10 stations Ask questions if you need help understanding transfers Focus on identifying energy stores and transfers
Reflection Questions
Which station showed the clearest energy transfer? Can you identify a station where energy was 'wasted'? How does the idea of energy 'shifting' change your thinking? What real-world examples can you think of?
Success Criteria Review
✓ Can you list the eight energy stores? ✓ Can you explain energy transfer as one store emptying, another filling? ✓ Did you observe and record energy transfers at all stations? ✓ Can you distinguish wanted from unwanted energy outputs? ✓ Did you follow safe laboratory procedures throughout?
