Begin the lesson by discussing the concept of light as a source of energy. Introduce the terms 'natural' and 'man-made' sources of light.

Engage students with a question: 'What are some things that give us light?' Encourage them to think about both day and night.

Explain that some sources of light are natural, like the sun, fire, and lightning, while others are man-made, such as flashlights and light bulbs.

Clarify that the moon is not a source of light but reflects light from the sun.

Watch the video 'Sources of Light' to see examples of natural and artificial light sources. This video helps students visualize the different sources and understand their importance.

Discuss with students: 'Can you name other sources of light?' Encourage them to share their ideas with the class.

Have students create a collage of images from magazines or drawings that represent different sources of light.

Use the 'What Is a Source of Light?' assessment to reinforce the identification of light sources. This activity helps students distinguish between natural and artificial sources.

Ask students to draw or list sources of light they see at home, categorizing them as natural or man-made.

Conduct a quick quiz using flashcards with images of different objects. Ask students to identify which are sources of light.

Review the main points of the lesson, emphasizing the difference between natural and man-made light sources.

Encourage students to reflect on how light is important in their daily lives.

Use the 'Does It Produce Light or Sound?' assessment to evaluate students' understanding of light sources versus sound sources. This activity reinforces the lesson's concepts through categorization.

Encourage students to explore additional sources of light in their environment and discuss their findings with peers.
