How do images form in spherical mirrors? That flexible piece of aluminum I used as a spherical mirror worked great! We experimented with different incident angles to get a feel for how the light rays would reflect. In the future, I should do this as a lab.

Later, we walked through the simplest way to locate images in concave mirrors. The kids got stuck when the object is on the focal point, at which point we problem-solved our way to a different approach that works. Virtual images are difficult.
