Begin the lesson by discussing the importance of light in our daily lives. Ask students to share examples of where they see light being used around them.

Introduce the concept of natural and artificial light sources. Use simple examples such as the sun and a flashlight to illustrate these concepts.

Explain how light helps us see in different environments, using examples like sunlight during the day and streetlights at night.

Discuss the role of light in technology and communication, such as in televisions and traffic signals.

Engage students in identifying various light sources in the classroom or at home. Encourage them to think about how these lights help them in their daily activities.

Use a flashlight to demonstrate how light can be directed and how it changes the appearance of objects in a dark room.

Have students create simple shadow puppets using their hands and a flashlight to explore how light and shadows interact.

Provide materials for students to create their own 'light and shadow' artwork, using paper cutouts and a light source.

Ask students to draw a picture of their favorite light source and write a sentence about how it helps them.

Encourage students to find and list light sources at home and describe their uses.

Use the 'What Is a Source of Light?' assessment to evaluate students' ability to identify light sources.

Have a class discussion about the different ways light is used for safety and communication, such as in traffic lights and emergency signals.

Reflect on the day's activities and ask students what new things they learned about light.

Administer the 'How We Use Light' assessment to gauge students' understanding of practical applications of light.

Encourage students to explore further by observing different light sources at home and discussing their findings with family members.
