1. Watch or Launch
Launch the Interactive
Open the simulation, adjust the controls, and compare what changes on screen before answering the concept-check questions.
2. Big Ideas
Key idea Conduction transfers thermal energy through materials because of a temperature difference. Heat-flow models make gradients, material differences, layer thickness, and steady-state behaviour visible.
What Students Can Learn
- Read temperature gradients as evidence of heat flow.
- Compare materials or layers by their effect on heat transfer.
- Relate thickness and thermal conductivity to thermal resistance.
- Distinguish steady-state heat flow from changing temperature over time.
Guiding Question
How do material, thickness, and temperature difference affect the heat flow through the rod or wall?
3. Try the Investigation
Find the Gradient
Identify hot and cold sides and describe how temperature changes across the material.
Change One Material Feature
Adjust material, layer, or thickness if available while keeping boundary temperatures comparable.
Watch the Heat Flow
Use the graph, colours, or numerical values to compare how heat transfer changes.
Explain Resistance
Connect the observed change to thermal conductivity, layer thickness, or thermal resistance.
4. Teacher Notes
Lesson Use
Use this as an evidence-based discussion of insulation and heat conduction. The key teaching move is to make students read the gradient rather than simply say heat moves from hot to cold.
Discussion Prompts
Ask: Which layer has the steepest temperature change? Which material slows heat flow most? What would make the wall a better insulator?
Teaching Moves
Run paired cases with one changed feature: same wall but different thickness, or same thickness but different material. Require students to cite the displayed gradient or heat-flow value.
5. Concept Check
These questions are generated from the topic and the concept illustrated by the simulation. Use them after students have explored the model.
