1. Lesson Starter Write down the meaning of the word conduction
Write down the meaning of the word convection
Write a description of what you think space is like

2. Heat

3. To understand how heat travels by radiation
Learning Intention
To understand how heat travels by radiation

4. Radiation
Instead heat is transferred by infra-red radiation which is in the form of waves of energy
Space is a vacuum so there are no particles for heat to transfer by convection or conduction

5. Infra Red Invisible Travel through vacuum Move at 300,000,000 m/s
All hot objects give out heat by radiation

6. Can be reflected Or Can be absorbed
Infrared
Can be reflected Or Can be absorbed

7. Experiment- learning intention
To safely carry out practical work while working as part of a group in order to find if the colour of a can affects heat loss.

8. Instruction Apparatus Shiny and black cans Thermometers timer
Bunsen burner
water
Add 150 ml of water to a shiny and black can.
Heat the water till it boils
Start the timer.
Measure the temperature of the water each minute for 12 minutes.

9. Temperature (°C) SHINY Temperature (°C) BLACK 1 2 3 4 5 6 7 8 9 10 11
Time (minutes)
Temperature (°C) SHINY
Temperature (°C) BLACK 1 2 3 4 5 6 7 8 9 10 11 12

10. Report Aim Method (apparatus, instructions and diagram)
Results (copy table and glue in graph)
Conclusion (What was the difference between the black and the shiny and why?)
Evaluation (what could be done differently next time to make the experiment more accurate?)
