Georgia S8P2.c
The Standard
Construct an argument to support a claim about the type of energy transformations within a system [e.g., lighting a match (light to heat), turning on a light (electrical to light)].
Georgia Standards of Excellence for Science · Obtain, evaluate, and communicate information about the law of conservation of energy to develop arguments that energy can transform from one form to another within a system.

What This Standard Means
What Students Need to Do
- Students identify the energy forms entering and leaving a system. They make a claim about the transformations, then support it with observations and scientific reasoning.
What Mastery Looks Like
- Students trace energy through a device or event using labeled arrows. They explain that energy changes form rather than appearing, disappearing, or being used up.
Common Misconceptions
- Students may confuse energy transformation with energy transfer between objects. They may name only the most visible output, such as light, and overlook thermal or sound energy.
How to Assess It
- Show a diagram of a battery-powered flashlight and ask: What energy transformations occur, and what evidence supports your answer?

Ways to Teach It
Connect a battery, wires, and small bulb, then have students diagram chemical, electrical, light, and thermal energy changes.
Ask students to explain why a toaster produces heat and light even though electrical energy enters the appliance.
Play an energy chain card game where students arrange source, transformation, output, and evidence cards for common devices.
Examine a phone charging and operating, then trace energy from the wall outlet to battery storage, light, sound, and heat.
