Activity

Māui and the Sun

In this activity, students are introduced to the concept of harnessing the Sun’s energy for our use on Earth. They will appreciate that the early Māori were also thinking about the Sun in relation to the Earth as depicted in the legend Māui and the Sun. The students will explore nuclear fusion (the nuclear reaction that releases energy in the Sun) and the electromagnetic spectrum (the energy waves that reach the Earth).

Illustration of Māui and his brothers harnessing the Sun.

Māui harnessing the Sun

In Māori mythology, Māui, with the help of his brothers, harnessed the sun to slow it down so that the days would be longer and they would all have more time to find food.

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

  • explain why the Sun is essential for life on Earth

  • explain nuclear fusion and the release of energy from the Sun

  • explain that the electromagnetic spectrum represents energy waves radiated from the Sun to the Earth.

Nature of science

When scientists make discoveries, they classify or categorise similar items so that they can keep track of everything and make references to various categories. The electromagnetic waves were categorised according to wavelength and frequency into seven different groups (see the electromagnetic spectrum).
