What do we mean by concave and convex mirrors? - Teacher's Notes

Concave and convex mirrors are curved reflective surfaces that manipulate light in different ways, and understanding how they work is the focus of this educational unit. Pupils are encouraged to explore these concepts through a combination of visual and practical learning methods. Initially, they are directed to watch online videos that demonstrate the properties of concave and convex mirrors, including how a common spoon can act as both types of mirror in a simple science experiment. These visual aids are meant to pique the students' curiosity and provide a foundation for their hands-on experiments.

Following the video demonstrations, pupils are expected to actively engage with the subject by conducting experiments similar to those they have seen online. This approach allows them to observe firsthand the effects these mirrors have on light and images. After the practical activities, pupils are provided with informational sheets that delve deeper into the theory behind concave and convex mirrors, aiding them in consolidating their understanding. By the end of the unit, students should be able to articulate the functions of concave and convex mirrors and record their explanations on the provided sheets. This structured approach ensures a comprehensive grasp of how these mirrors affect our perception of light and images.
