The eye - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 7 class.
This is the 4th lesson in “Chapter 3 - Light” from Activate 1, Physics. This lesson focuses on the eye, from the pages ‘the eye and the camera’. I have separated these into two lessons.
This lesson should be suitable to teach to any KS3 Physics class, even by those where physics is not their specialism.
This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks.
This lesson includes a short practical where students view inverted images through a magnifying glass.

From this lesson, students should be able to:

• Label the structures in the eye (pupil, cornea, iris, lens, retina, optic nerve)
• Describe the function of each of the structures in the eye (pupil, cornea, iris, lens, retina, optic nerve)
• Describe how the lens inverts images
• Describe the role of photoreceptor cells in the retina

All of my lesson resources contain:

• A 5-in-5 retrieval-style starter
• An interesting lesson hook, careers link, or retrieval practice to start the lesson
• Teacher input slides with dual coding and reduced cognitive load
• Teacher models
• Regular ‘check for understanding’ slides, such as hand signals quizzes
• Regular student independent practice slides, with optional scaffolds, challenges and answer slides
• A plenary task
