Resources to Address This

  • Heat rises (11-14)

    Ref - SPT; En05 TL05

    The idea of heat rising is very common in everyday speech and adds to the notion of heat being some kind of substance. In teaching about convection, it is therefore important to refer explicitly to the air being warmed up, reducing in density and rising through the colder surrounding air.

  • A model of vibrating atoms in a solid (11-16)

    Ref - Practical Physics; Molecules; Thermal expansion; A model of vibrating atoms in a solid

    1. The model is used as a prop to support a discussion of the way in which the particles in a solid are held together by spring-like forces.
    2. Show the model to the class and demonstrate how vibrating it will shake the individual atoms, but that they can retain their place in the overall pattern.
