Long ago, according to the legend of Māui, the Sun was the focus of attention. People wanted more daylight and warmth to get their jobs done. Māui schemed to harness the Sun.
Scientists today know the Sun produces huge amounts of energy and some of this energy is radiated to the Earth. They know the Sun’s energy is essential for life on Earth. It provides all living things with food, and it warms the Earth.
Scientists have learned that the Sun’s energy is transformed to different forms of energy on Earth (such as food energy and heat energy). Scientists are now discovering that they can transform some of this energy themselves – to make electricity. They are learning to harness the Sun!
Our resources on teaching about solar energy assist teachers to get across a number of important science ideas about solar energy to their students.
The learning outcomes of this teacher resources are that students will:
- understand the Sun is needed for life
- understand light and heat is transmitted from the Sun
- understand solar energy is weather- and distance-dependent
- understand solar energy can be reflected or absorbed
- appreciate that scientists collaborate with their work on solar energy and their knowledge on solar energy has developed over time
- use some of the language associated with solar energy and have a working knowledge of these terms
- think critically and ethically when exploring issues related to energy resources.
Students will meet these learning outcomes by:
- researching solar energy using Science Learning Hub resources
- investigating technology using solar power
- experimenting with the effects of heat on colour
- constructing a solar oven.
