How can we tell what the sun is made from? What can light from the stars tell us?

Lesson idea. As this slide presentation explains in more detail, we can tell what the sun is made from by the light wavelengths that we see emitted and absorbed. The presentation includes video and in an accompanying audio file, the teacher explains what it aims to do. See other titles in this series to appreciate the 'active note taking' which normally accompanies this lesson.

Teaching approach. The lesson model is that of active note-making. Students are provided with mini-diagrams* around which they build up personalised notes about the lesson. Students must not take notes from the board but instead must use their creativity to develop their own notes. They are encouraged to use colour, image, symbols, humour and metaphor to lead them through a richer learning experience. Students need help in achieving this but soon catch onto the idea. They become more independent with taking notes and more attentive to the subject at hand.
