Heat sources and temperature change
Identify sources of heat energy (sun, fire, heaters, friction, bodies) and examine how the temperatures of two objects change as heat energy moves from the hotter to the cooler one until they reach the same temperature
Lesson
Set out your lesson
“Heat sources and temperature change means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A small toy car or ball
- A ramp or book stack and a ruler
Extra for the adult
Worked example. A stronger push sends the car farther down the table than a gentle push.
Optional challenge. For Heat sources and temperature change, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Heat sources and temperature change, not mastery.

Heat sources and temperature change means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A small toy car or ball; A ramp or book stack and a ruler. 1. Say the goal of Heat sources and temperature change in plain words once. 2. Adult gives one gentle push and one stronger push, then compares how far the object travels. 3. Child tries three push or pull trials and records which force made a bigger change. 4. Fresh check: one fresh push/pull comparison. Record and stop. Done: three recorded trials with a clear force comparison. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- List heat sources around school and home, including rubbing hands together (friction) and body heat
- Measure every two minutes the temperatures of a cup of warm water standing in a tub of cool water and record that the warm water cools while the cool water warms
- Explain from the results that heat moves from the hotter object to the cooler one until their temperatures are about the same
“If your child puts a warm drink into a bowl of cold water, can they predict and measure that the drink cools down while the cold water warms up?”
