HS-PS3-1
The standard
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Next Generation Science Standards
What this standard means
Students need to track energy like a budget. If energy enters, leaves, or moves between parts of a system, they should use basic algebra to find the missing energy change for one part. They also need to explain what each term means, not just plug numbers into a formula.
Mastery looks like a clear energy model with labeled components, arrows for energy transfer, correct signs, and a correct calculation. Students often get stuck on positive and negative values, mixing up energy transfer with energy stored, or forgetting to define the system boundary.
Ways to teach it
- Give groups energy cards for a roller coaster, track, and surroundings, then have them arrange cards and calculate a missing energy change.
- Ask students to write what each term means in ΔEcart + ΔEtrack = Einput − Eout, using one sentence per term.
- Use an exit ticket with a two-component system and one missing value, asking for the equation, answer, and sign explanation.
- Have students model a phone charging, showing energy entering the battery, warming the phone, and leaving to the room.
