- Temperature vs. heat.
- Measuring temperature.
- Transmission of heat by conduction; conductors vs. insulators.
- Transmission of heat by convection; convection in the troposphere; convection in the asthenosphere.
- Transmission of heat by radiation.

Eureka! - Temperature vs. heat
Learn the difference between "degree of hotness" and "quantity of hotness".
Eureka! - Measuring temperature
You need something better than just "too cold" or "too hot", don't you? Learn how Anders Celsius came up with the solution…
Eureka! - Heat as energy
Learn that heat is just another kind of energy, and can be transmitted.
Temperature
Can an individual atom be hot or cold? Can it even have a temperature? Find out now!
Eureka! - Conduction
Learn that heat can be transmitted by the vibration of an atom (or molecules) to its neighbours… which is what makes metals be so good heat conductors.
Eureka! - Convection
Learn that heat can also be conveyed by fluids thanks to the principle of buoyancy.
Eureka! - Radiation
And lastly, heat can also travel in the form of waves.
