A convex mirror is bent outwards and distorts the image. The image is always right side up and small. In a concave mirror, when an object is out of focus, the reflection will appear inverted. When it is in focus, it appears upright and large.
Have students use a spoon to understand the difference of the appearance with the two mirrors. The inside of the spoon is the concave side and the convex would be the outside of the spoon.
Purpose: to understand how images look in both mirros
Introduce: This activity is the perfect introduction to the topic in itself!
Difficulties: Being able to get an accurate representation of the image in a concave mirror in focus
Changes: Finding actual mirrors that are concave and convex so students can better see the concept
