Mississippi Science PHS.7.2
The Standard
- PHS.7
- Students will examine different forms of energy and energy transformations.
Use scientific investigations to explore the transformation of energy from one type to another (e.g., potential to kinetic energy, and mechanical, chemical, electrical, thermal, radiant, and nuclear energy interactions).

What This Standard Means
What Students Need to Do
- Students run tests and use measurements to track energy as it changes form. They identify what energy enters and leaves a system, including heat and sound that are easy to miss.
What Mastery Looks Like
- A student uses ramp heights and video measurements to show that a marble speeds up as stored energy becomes motion. They can also trace a battery's chemical energy into light and heat without claiming energy was created or lost.
Common Misconceptions
- Students often say energy is used up when a marble stops, missing the heat and sound from friction. Some think a battery stores electrical energy rather than chemical energy.
How to Assess It
- Exit ticket: A battery lights a bulb and the bulb gets warm. Ask students to name the energy changes in order and cite an observation for each output.

Ways to Teach It
Roll a marble from two marked ramp heights, measure its speed near the bottom with slow-motion video, and compare results.
Show a photo of a lit flashlight and ask students to write where the battery's energy goes besides visible light.
Give pairs battery, bulb, solar cell, motor, chemical, electrical, radiant, and motion cards; ask them to build two valid energy chains.
Display a nuclear power plant diagram and ask students to trace energy from nuclear fuel through heat and turbine motion to electricity.
