This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants calculate the total reflectance from an optical window of finite thickness. Equipment includes a red laser diode module, laser holder, optical block, cardboard, a ruler, protractor, pencil, and...

In this exercise, created by Anna Jensen, students take part in a roller coaster design challenge. As part of the challenge, students will attempt to optimize ride time and thrills for the prospective rider while also trying to keep costs reasonable. The exercise, designed with the intention of...

This is an animation of a Schmitt trigger circuit with clean input voltage. Voltages and parts of the circuit of this 3-D animated .gif are highlighted with different colors. Current is displayed by green arrows indicating directional flow.

This video from Laser-Tec is part of a series of light and optics experiments. This lab explores the basics of semiconductor laser diodes. The construction fixture of the diode, the focusing optics that collimate a diverging beam, and laser safety are highlighted. Equipment includes a red laser...

This 44-page teachers guide, provided by Maricopa Advanced Technology Education Center (MATEC), includes semiconductor science activities. The student activities in this packet are designed to be incorporated into a standard high school physics curriculum. The intent is to provide the student with...

There are many curriculum materials, professional development, and student enrichment activities available on this website. These resources are designed for teachers and students ranging from K-12 through higher education. Most resources are interactive and engage the students on many different...

This lab, presented by the National Nanotechnology Infrastructure Network, teaches students how to measure the efficiency of a solar cell. Students will compare the output power of a silicon PV cell with the input power of incandescent light bulbs illuminating the PV from a set distance. A Teacher's...

This video from Laser-Tec is part of a series of light and optics experiments. This lab explores simple periscopes, which are optical systems used in marine settings. The experiment provides a real-world example of the refraction and reflection of light, as well as the use of lenses, prisms, and...

This lesson, presented by the National Nanotechnology Infrastructure Network, covers the concept of solar ovens. In this lesson, students will learn how "thermal energy flows from the hot air to the cold water via conduction and will indicate that this would continue to happen until the water sample...

This resource, provided by Piedmont Virginia Community College, includes files for a project-based learning module that has students learn about OHM's law while building a solder exhaust fan. This project is intended for introductory electronics courses. During the project, students are introduced...
