Lesson Plan version 1.1 activites
1.Ask the students if they have metallic pencil boxes or lunch boxes. Ask them to try to see the reflection of their faces on these surfaces. They can even try to see the images formed through the glass on the classroom windows (if any). Let them explain why are the images not as clear as what they see in a mirror. You can sum up the concept of diffused reflection in the end.
