Georgia S8P2.d
The Standard
Plan and carry out investigations on the effects of heat transfer on molecular motion as it relates to the collision of atoms (conduction), through space (radiation), or in currents in a liquid or a gas (convection).
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 plan and run fair tests that track temperature changes during conduction, convection, and radiation. They use particle motion and collisions to explain the evidence they collect.
What Mastery Looks Like
- Students control variables, record temperature data, and identify the heat transfer method shown. They explain that conduction uses particle collisions, convection moves warmer fluids, and radiation transfers energy through electromagnetic waves.
Common Misconceptions
- Students may say cold moves into an object or that heat always rises. They may think particles travel through a solid during conduction, or that radiation needs matter to travel.
How to Assess It
- Exit ticket: A metal spoon sits in hot soup under a heat lamp. Identify two heat transfer methods and explain each using particles or waves.

Ways to Teach It
Rotate through stations using metal and wood spoons, a heat lamp, and food coloring in warm water to observe each transfer method.
Write an explanation answering, “Why does a metal spoon heat faster than a wooden spoon in hot water?”
Sort scenario cards into conduction, convection, or radiation, then defend one disputed card using particle motion or waves.
Map how conduction, convection, and radiation each transfer energy while a pot of soup cooks on a stove.
