Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson on...

Students investigate the law of reflection by using mirrors. In this physics lesson, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating...

Nobody is as smart as all of us together. In a collaborative learning activity, scholars learn it takes a team to be successful in laparoscopic surgeries. Groups complete the laparoscopic task as a team and discuss their results to...

Article explaining what Digital Light Processing (DLP) technology is and how it works. Includes an animation to demonstrate the technology. (Published Fall 2007)

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"...
