Energy | Project Based Learning
Students investigate how energy is transformed and conserved, then work in teams to design, build, and test a simple energy-saving prototype or model solution to a real-world problem. The lesson uses project-based learning to connect scientific concepts to engineering design and data analysis.
| Term | Definition |
|---|---|
| Energy | The ability to do work or cause change. |
| Potential Energy | Stored energy due to position or condition. |
| Kinetic Energy | Energy of motion. |
| Transfer | The movement of energy from one object or system to another. |
| Transformation | The change of energy from one form to another. |
| Efficiency | How well a device or system uses energy with little waste. |
| Thermal Energy | Energy related to the motion of particles; often felt as heat. |
| Prototype | A first model built to test an idea. |
Present a simple challenge such as: 'How can we design a classroom item, device, or model that reduces energy waste or uses energy more efficiently?' Show a quick example of energy loss in a common device or system.
Observe, discuss prior knowledge, and brainstorm where energy might be wasted or conserved in everyday life.
Organize students into teams and provide the project prompt, constraints, and success criteria. Guide teams to identify the problem they will solve and sketch a design plan.
Work in teams to define the problem, record ideas, and choose one design to test.
Briefly review energy forms, transfer, transformation, and efficiency using examples. Model how to connect a design feature to an energy change.
Take notes, ask questions, and connect vocabulary to the project challenge.
Circulate, ask probing questions, and support teams as they build and test prototypes. Encourage data collection and at least one design revision.
Construct a prototype or model, test it, record results, and revise the design based on evidence.
Facilitate quick team presentations or gallery walk. Ask teams to explain how their design addresses energy efficiency and what evidence supports their claim.
Present findings, compare solutions, and reflect on what worked, what did not, and why.
End with a brief class share-out: each team names one energy transformation, one design improvement, and one piece of evidence from testing. Reinforce that engineers use data to improve solutions.
Formative assessment: teacher observation, design sketch review, data table check, and student explanations during share-out. Summative assessment: evaluate the team prototype, design process, and short reflection using a rubric for understanding of energy concepts, evidence-based reasoning, collaboration, and communication.
Students write a short reflection at home: identify one household or school device that could be more energy efficient, describe the energy transformation involved, and propose one improvement with a reason.
