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...

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"...
