    In this activity, students use a shallow tray of water to demonstrate wave generation and behaviour.

    By the end of this activity, students should be able to:

    • demonstrate how surf and tsunami waves originate
    • demonstrate how surf and tsunami waves interact with the ocean floor
    • demonstrate how wave height (amplitude) is increased due to shoaling.

    Nature of science

    Models are a way of visualising something we cannot safely or directly observe. The wave tank model helps us to represent surf and tsunami waves, but not with complete accuracy.

    The level 3 Connected article Building for the future looks at how a scientist uses scientific modelling and is working with others to build a safer future for a Samoan village.
