Unit: Heat Energy Transfer

Resources

Lessons

1. Heat V Temperature

   *To understand the difference between: heat energy and temperature
   *To understand the Celsius scale and how it is derived
   *To know how to use a thermometer correctly and discuss pro/con of different scales
   

    
2. Conduction

   *To understand how heat energy is transferred through an object, using the particle model
   *To understand the difference between a conductor and an insulator, and the effect of free electrons in metals
   

    
3. Convection

   *To understand how heat energy is transferred through a fluid, using particle model.
   *To connect convection with density.
   *To be able to provide everyday consequences, examples and applications.
   

    
4. Radiation and Insulation

   *To understand how heat energy is transferred by IR radiation
   *To understand that no medium is required – electromagnetic wave
   *To understand which media transmit/emit/absorb best/worst
   *To be able to apply conduction, convection and radiation to a situation e.g. explaining how a vacuum flask works
   *To design an experiment that allows choice of suitable materials to stop heat transfer.

    
5. Expansion and Contraction

   *To understand how and why materials expand and contract
   *To describe applications, consequences and examples of contraction and expansion
