Energy Stores and Transfers
An introduction to the different ways energy can be stored and transferred between systems. Students will calculate kinetic, gravitational, and elastic potential energy.
TL;DR:Energy Stores and Transfers introduces the fundamental principle that energy cannot be created or destroyed, only moved between stores. Students learn to identify different stores, such as kinetic, gravitational potential, and thermal, and the pathways by which energy is transferred. The topic includes the mathematical application of formulas for kinetic and potential energy.

This unit is a vital part of the GCSE Physics component, providing the language and framework for all subsequent physics topics. It requires students to move away from the idea of energy being 'used up' and instead focus on dissipation and efficiency. This topic comes alive when students can physically model the patterns of energy movement in real-world systems.
Key Questions
- What are the main energy stores and how is energy transferred?
- How do we calculate the energy associated with a moving object?
- What is the principle of conservation of energy?
Watch Out for These Misconceptions
Common MisconceptionStudents often think energy is a physical substance that flows like a liquid.
What to Teach Instead
Explain that energy is a property of a system, not a 'thing'. Using the analogy of money in different bank accounts (stores) can help students understand that energy is just being shifted around.
Common MisconceptionThere is a common belief that energy is 'lost' when a system is inefficient.
What to Teach Instead
Clarify that energy is never lost, only dissipated to the surroundings, usually as heat. Peer discussion about why a phone gets hot during use can help illustrate this concept of wasted energy.
Active Learning Ideas

Bouncing Balls
Groups drop different balls from various heights. They calculate the gravitational potential energy at the start and the kinetic energy just before impact, discussing where the 'lost' energy went.
Think-Pair-Share
Energy Circus
Display several toys (wind-up car, torch, battery fan). Students work in pairs to identify the starting energy store, the transfer pathway, and the final energy stores for each item.
Simulation Game
Sankey Diagram Challenge
Students are given data for a lightbulb or engine. They must use graph paper or digital tools to draw a Sankey diagram to scale, showing useful energy versus wasted energy.

Planning templates for Combined 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.
