Lesson 5: Refraction

Learning Intention: To understand the concept of refraction and its effects.

Introduction: Begin the lesson by asking the students if they know anything about refraction. Allow a brief discussion and then show them the following video: - Video: “Introduction to Refraction” (https://www.youtube.com/watch?v=nR5EarZ2iSg)

Main Activity: 1. Provide each student with a printed diagram of refraction and ask them to stick it into their science books. 2. Instruct the students to write a brief explanation of their understanding of refraction in their own words. This can be done individually or in pairs. 3. After they have completed their explanations, ask a few students to share their understanding with the class.

Experiment: 1. Distribute glass objects and torches to the students. If necessary, obtain these materials from Jackson. 2. Instruct the students to shine the torch through the glass objects and observe if they can see all the different colors. They can also try this experiment with sunlight. 3. Encourage the students to record their observations and any patterns they notice.

Resources: - Printed diagram of refraction for each student - Video: “Introduction to Refraction” (https://www.youtube.com/watch?v=nR5EarZ2iSg) - Science books - Torches and glass objects (obtained from Jackson)

Extension: For higher ability students, challenge them to research and explain real-life examples of refraction, such as the bending of light in a prism or the formation of rainbows. They can present their findings to the class or create a poster to display in the classroom.
