5-SLG-3

Outcomes

• Pupils can describe Brownian motion
• Pupils can convert °C and K

Specification References

• 5.9 understand the significance of Brownian motion, as supporting evidence for particle theory
• 5.10 understand that molecules in a gas have a random motion and that they exert a force and hence a pressure on the walls of the container
• 5.11 understand why there is an absolute zero of temperature which is –273°C
• 5.12 describe the Kelvin scale of temperature and be able to convert between the Kelvin and Celsius scales

Starter

Demo Brownian motion (microscope) and here's an animation which shows what's going on.
