Begin the lesson by introducing the concept of the Sun as the largest object in our solar system. Discuss its significance in maintaining the solar system's structure through gravitational forces.

Introduce the concept of an astronomical unit (AU) and its importance in measuring distances within the solar system.

Explain the layers of the Sun, including the core, radiative zone, convection zone, photosphere, chromosphere, and corona, and their roles in solar phenomena.

Discuss the process of nuclear reactions in the Sun's core and how they contribute to the Sun's heat and light.

Watch the video 'Life on Earth – The Habitable Zone' to understand how Earth's position in the solar system's habitable zone supports life.

Engage students in a discussion about the Sun's role in the solar system and its impact on Earth.

Have students create a model of the Sun, labeling its different layers and explaining their functions.

Use the 'Galaxy Classification' assessment to explore different types of galaxies and their characteristics.

Assign students to research the life cycle of the Sun, from its formation to its eventual transformation into a red giant and white dwarf.

Have students complete the 'Brightness of Stars' assessment to understand how distance affects star brightness.

Conduct a Q&A session to assess students' understanding of the Sun's composition and its significance in the solar system.

Use the 'The Sun' assessment to evaluate students' knowledge of the Sun's distance, composition, and structure.

Summarize the key concepts learned about the Sun, its layers, and its role in the solar system.

Encourage students to reflect on how the Sun's characteristics affect life on Earth.

Administer the 'Review – The Universe' assessment to test students' comprehension of the Sun and its place in the universe.

For further exploration, encourage students to investigate the impact of solar phenomena on Earth, such as solar flares and auroras.
