Potential EnergyActivities & Teaching Strategies
Active learning works especially well for potential energy because students need to see stored energy in action, not just hear about it. When students manipulate ramps, springs, or pendulums, they connect abstract formulas like GPE = mgh to real motion, making the concept more memorable and intuitive.
Ready-to-Use Activities
Gravitational Potential Energy Lab: Height vs. Energy
Students drop objects of varying masses from different heights and measure the resulting kinetic energy (e.g., by how far they knock over a target). They then calculate the initial gravitational potential energy for each drop.
Prepare & details
Explain how an object's position or state can store potential energy.
Facilitation Tip: During Lab Investigation: Gravitational Potential Energy and Ramp Height, circulate and ask each group to predict how changing the ramp height will affect the final speed of the cart before they begin testing.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Elastic Potential Energy: Spring Compression
Using spring scales or custom spring setups, students compress or stretch springs by measured amounts and record the force required. They then calculate the elastic potential energy stored in the spring.
Prepare & details
Analyze the factors that influence gravitational potential energy.
Facilitation Tip: For Calculation Practice: GPE = mgh, model how to choose a reference point and solve two versions of the same problem using different h values before students work independently.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Roller Coaster Design Challenge
Students design and build a simple roller coaster track using craft materials. They must incorporate hills that demonstrate the conversion of potential to kinetic energy and explain how height changes affect the ride's speed.
Prepare & details
Predict how changing an object's height will affect its potential energy.
Facilitation Tip: In Think-Pair-Share: Elastic vs. Gravitational Potential Energy, assign pairs one elastic item and one elevated object to contrast, then have them present their comparisons to the class.

Teaching This Topic
Teach potential energy by starting with concrete, hands-on experiences before introducing formulas. Avoid overwhelming students with too many variables at once—introduce one concept (like height or mass) at a time. Research shows that students grasp energy conservation best when they observe the same system multiple times, so repeat experiments with slight variations to reinforce understanding. Always connect back to the core idea: potential energy is the capacity for motion, not just height or falling.
What to Expect
Successful learning looks like students confidently identifying potential energy in different situations, using the correct terms for each type, and explaining how energy transfers between potential and kinetic forms during motion. They should also recognize that reference points are flexible and that energy conservation applies across all scenarios.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Lab Investigation: Gravitational Potential Energy and Ramp Height, watch for students who assume the cart’s speed depends only on the height of the ramp, not considering the mass or friction.
What to Teach Instead
After students collect data, ask them to compare two runs with the same ramp height but different cart masses. Have them calculate GPE for each and discuss why the speed differences appear.
Common MisconceptionDuring Calculation Practice: GPE = mgh, watch for students who treat the reference point as fixed, always using the floor as h = 0 without considering the scenario.
What to Teach Instead
Have students solve the same problem twice—once with the floor as h = 0 and once with the tabletop as h = 0—and compare the GPE values to emphasize that differences matter, not absolute values.
Common MisconceptionDuring Pendulum Exploration: Height and Speed, watch for students who think the pendulum’s speed is the same at every height due to energy conservation.
What to Teach Instead
Ask students to measure the pendulum’s speed at three points: release, halfway down, and bottom. Have them graph the results to visualize where kinetic energy is greatest and least.
Assessment Ideas
After Calculation Practice: GPE = mgh, present students with three objects at different heights and ask them to write which has the most GPE and why. Then, show a stretched rubber band and ask if it stores elastic potential energy, reinforcing the distinction between GPE and EPE.
During Lab Investigation: Gravitational Potential Energy and Ramp Height, have students answer: 1. If you double the height of the ramp, what happens to the cart’s GPE? 2. Describe one real-life situation where elastic potential energy is stored.
After Pendulum Exploration: Height and Speed, pose the question: 'What factors determine the pendulum’s potential energy at the top? What happens to that energy as it swings to the bottom?' Guide the discussion to use terms like GPE, mass, height, and kinetic energy conversion.
Extensions & Scaffolding
- Challenge students to design a catapult using rubber bands that launches a small object to a target, calculating the elastic potential energy stored and predicting the launch distance.
- For students who struggle, provide pre-labeled diagrams with missing variables (m, g, h) and ask them to fill in the values before solving GPE = mgh.
- Deeper exploration: Ask students to research how potential energy is stored in everyday technology (batteries, stretched bows, coiled springs) and present one example to the class with an energy conversion diagram.
