Florida SC.3.P.11.2
The Standard
Investigate, observe, and explain that heat is produced when one object rubs against another, such as rubbing one's hands together.

What This Standard Means
What Students Need to Do
- Students test what happens when two surfaces rub together. They observe a temperature change and connect the warming to friction between the surfaces.
What Mastery Looks Like
- Students can conduct a simple rubbing test and record evidence of warming. They can explain that friction at the touching surfaces produces heat.
Common Misconceptions
- Students may think movement alone causes warming, even when surfaces do not rub. They may also think only one surface warms or that the heat comes from the surrounding air.
How to Assess It
- Exit ticket: Sam rubs an eraser across carpet for 30 seconds. Predict what happens to its temperature and explain why.

Ways to Teach It
Have pairs use an infrared thermometer to check an eraser, rub it on carpet for 30 seconds, then check it again.
Ask students to write: Why do your hands feel warmer after rubbing, but not after holding them still?
Play a matching game with action cards, observation cards, and explanation cards showing where rubbing produces heat.
Examine bicycle brake pads and discuss why they warm when they press against a moving wheel.
