Begin the lesson by introducing the concept of shadows and how they are formed when light is blocked by objects. Use real-life examples such as observing shadows on a sunny day.

Engage students with a question: 'Have you ever noticed how your shadow changes throughout the day?' This will pique their curiosity about the topic.

Explain the difference between transparent, translucent, and opaque objects, and how each affects shadow formation. Use diagrams to illustrate these concepts.

Discuss how the position of the Sun affects the size and shape of shadows throughout the day. Use a flashlight and objects to demonstrate this in class.

Watch the video 'Changing the Size of Shadows' to see how the position of a light source and an object affects the size of the shadow formed. This visual demonstration enhances understanding of basic principles of light and shadow formation.

Encourage students to explore shadows by moving objects closer to and further from a light source and observing the changes.

Conduct an experiment where students create shadows using various objects and light sources. Have them record their observations about shadow size and shape.

Use the 'Make a Sundial' assessment to help students learn about time measurement and the Earth's rotation. This hands-on activity involves marking shadow positions hourly.

Assign students to observe and record the changes in their own shadows at different times of the day. They should note the size, shape, and direction of the shadows.

Have students complete the 'How Light Travels – Comprehension' worksheet to reinforce their understanding of light as a wave and its properties.

Conduct a class discussion to review the key concepts of shadows, light, and how different objects affect shadow formation. Ask students to share their observations from the independent practice.

Use the 'Reflection Challenge' assessment to test students' understanding of light reflection and how it relates to shadow formation.

Summarize the lesson by revisiting the learning objectives and discussing how they were achieved. Highlight the importance of understanding light and shadows in everyday life.

Encourage students to reflect on what they learned and how they can apply this knowledge in real-world situations.

Administer the 'Review – Energy' assessment to evaluate students' comprehension of energy and light concepts, including shadow formation.

Provide extension activities for students who grasped the concepts quickly, such as researching how shadows are used in art and photography.
