Teaching Laws of reflection to Jr High students presented a problem to me until I started to use this activity.
Students develop the Laws of Refection by use of their own experimentation and observation.
I give them as little help as possible making them come up with something that will work. The student must write in report form what ever procedure and conclusions that come from the activity. To develop the basic Laws of Reflection by observation of images of objects in plane mirrors. I let the students develop their own experiments. 1. draw a line across the center of a sheet of paper this becomes the reflective line in the experiment.
