Students apply everything they have learned about light properties and laser technologies to designing, constructing and presenting laser-based security systems that protect the school's mummified troll. In the associated activity,...

Students learn abouT the Law of Reflection by constructing an equilateral triangle using graph paper, pencil, protractor, and a ruler and a "laser triangle" using a laser pointer and front-silvered mirrors.

Students use simple household materials, such as PVC piping and compact mirrors, to construct models of laser-based security systems. The protected object (a "mummified troll" or another treasure of your choosing) is placed "on display"...

Inspired by a work site using a laser to measure in the water, this teacher decided to do a project-based learning lesson with students the required them building an obstacle course that they had to maneuver a laser beam around. Part of...

An interesting and engaging activity where students work in groups with a laser pointer and small mirrors. They must use their knowledge of angles of reflection to bounce the laser beam from mirror to mirror until it hits a target at the...
