This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants pass white light through a diffraction to separate and view all colors of the light spectrum. Participants learn about the order of colors in the light spectrum and different types of spectra...

This web site provides information on three topics: fundamental physical constant, the International System of Units (SI), and expressing the uncertainty of measurement results. This site contains a checklist of rules and style conventions for proper SI usage and rules for correct typefaces for...

The Physics Classroom site is an online portal for introductory physics students. The tutorials were originally developed for physics students at Glenbrook South High School in Glenview, Illinois. The 13 tutorials cover basic physics topics using informative graphics and an easy-to-understand...

This Web site features a series of animations showing the operation of a vortex flowmeter that is used to measure flow in a process control system. Besides defining a vortex flowmeter, a Flash animation shows how it causes vortices around a blunt object obstructing the flow. A sine wave flow is...

This learning module from the Northeast Advanced Technological Education Center (NEATEC) explores thin films. Educators can incorporate this module into an existing STEM class. Essential questions and objectives of the learning module are provided alongside New York state's common core learning...

This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants calculate the total internal reflection in an acrylic rod. Snell's Law and the critical angle are also highlighted. Equipment includes a laser pointer, acrylic rod, protractor, pencil, and white...

This lab, presented by the National Nanotechnology Infrastructure Network, teaches students how to measure the wavelength of a laser. Furthermore, students will calculate the uncertainty in their measurement as it is "critical to have accurate measurements on the nanoscale." A Teacher's Preparatory...

During this 2-page learning activity, from the Advanced Technology Environmental and Energy Center, students research the sources of radiation at the surface of the earth. Students will also research how radiation is measured, collect data, enter data into a spreadsheet, and learn how to report the...

This lab, presented by the National Nanotechnology Infrastructure Network, covers the concept of wave properties. Students will learn how light waves interact with matter. The activity is "analogous to light traveling through optical media having different indices of refraction (densities)." Teacher...

This exercise, presented by the National Nanotechnology Infrastructure Network, covers the concept of waveguides. Students will explore the "angle of incidence, angle of refraction, and how light is transmitted through a waveguide for communication." Students have the option to do this lesson as...
