Begin the lesson by discussing the concept of light and shadows. Ask students if they have ever noticed their shadow on a sunny day and what they think causes it.

Light and Shadows
Learning Objectives
- Identify objects that can block light and create shadows.
- Describe how the shape of a shadow is similar to the shape of the object making the shadow.
- Experiment with light sources, like a flashlight, to create and change shadows.
- Understand that shadows are created when an object blocks light.
Introduction and Hook
Direct Instruction
Explain that shadows are created when an object blocks light. Use simple examples like a hand blocking a flashlight to demonstrate.
Introduce the video 'All About Light' to help students understand light as a form of energy and its role in creating shadows.
Guided Exploration
Engage students with the video 'Changing the Size of Shadows' to explore how the position of light affects shadow size. Discuss how moving the light source closer or further changes the shadow.
Encourage students to use flashlights and objects to create their own shadows and observe changes in size and shape.
Hands-On Activity
Have students experiment with creating shadows using different objects and light sources. Provide materials like flashlights, paper, and small toys.
Guide students to observe and describe how the shape of the shadow matches the object blocking the light.
Independent Practice
Assign the 'Observing Shadows' worksheet to reinforce the concept of shadows and their formation. Students will identify objects creating shadows in images.
Check for Understanding
Conduct a quick quiz using the 'Review – Sound and Light' assessment to evaluate students' grasp of light and shadow concepts.
Try the QuizReview and Reflection
Discuss with students what they learned about shadows and light. Encourage them to share their experiences and observations from the hands-on activities.
Assessment and Extension
For further exploration, use the 'How We Use Light' assessment to connect the concept of light to everyday applications.
