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 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 young scholars 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...
