Objectives/WALT
• Investigate the refractive index of different materials.
• Utilise Snell’s Law.
An observed lesson for KS4 pupils on refractive index. Fully differentiated with mini-plenaries after each activity.
P3 L3. This lesson got an outstanding by OFSTED that came into visit. Includes an array of different activities and is tailored to the elite/gifted and talented pupils. Includes answers to the worksheets as well as sample results if the practical is not completed in time by groups.
Changing State Starter
Describe what infrared radiation is in terms of the electromagnetic spectrum
Explain that the hotter an object is, the more infrared radiation it emits in a given time.
Apply your knowledge of infrared radiation to given scenarios
Differentiated Questions based on a short video.
