Begin the lesson by introducing the concept of astronomical units (AU) and light years, which are essential for understanding distances in space. Highlight their significance in measuring the vast distances between celestial bodies.

Engage students with a brief discussion on the closest star system to our Sun, the Alpha Centauri system, and its importance in astronomy.

Explain the visual differences and similarities between stars like Alpha Centauri A, B, and C, as well as Sirius and Canopus. Highlight their brightness and distance from Earth.

Discuss how the visibility of stars from Earth changes with the Earth's rotation and orbit around the Sun.

Watch the video 'Space Exploration – Beyond Our Planet' to understand how telescopes and other technologies help us study stars and celestial bodies.

Conduct a hands-on activity where students create a model to simulate the Earth's rotation and its effect on star visibility using simple materials like a globe and a flashlight.

Assign students to research and compare the brightness and distance of prominent stars such as Sirius, Canopus, and the Alpha Centauri system. Encourage them to present their findings in a short report.

Use the 'Space' assessment sheet to test students' understanding of space-related concepts, including the solar system and stars. This assessment encourages reflection and inquiry.

Facilitate a class discussion to review the key concepts learned about stars and their visibility. Encourage students to share their insights and reflections on the lesson.

Administer the 'Review – Space' assessment to evaluate students' comprehension of the unit's key concepts, such as Earth's rotation and the solar system's structure.

For further exploration, encourage students to engage in the 'Movement of Stars Across the Sky' activity, which involves observing and tracking star movements.
