Human ingenuity
Objective:
Students will learn some of the properties of lasers.
Agenda:
1. Discussion:
Share results of pinhole camera pictures. Show some of the samples, pass them around. Indicate that I still need to scan these pictures.
2. Activity:
Safety discussion about lasers. Indicate that one can never ever shine them into someone's eyes, and for safety we will avoid sending them towards other people if at all possible. This is because even though the laser light is not that bright, it is concentrated more than a typical flashlight would be. Discuss our challenge, have a laser hit all of the mirrors.
3. Activity:
Measuring the angle of reflection and incidence.
Homework:
None
