This lab activity, presented by John Chamberlain, examines the effects of prisms and lenses on light emitted from a laser. In first part of the twelve-minute video, Chamberlain demonstrates refraction of light through a prism, and the measurement and calculation of the angle of deviation produced...

This lab activity, presented by John Chamberlain, covers the the polarization of light using filters. In this four-minute video, Chamberlain demonstrates the use of a flashlight, stand, reflective surface, and polarizing filters (including one used as an analyzer) to examine planes of polarization. ...

This lab activity, presented by John Chamberlain, examines the spectrum of colored light as it passes through a diffraction grating. In this four-minute video, Chamberlain demonstrates the use of color filters, stands, a flashlight, and the diffraction grating to identify and modify ranges of color...

This lab activity, presented by John Chamberlain, covers the basics of windows and mirrors as the two relate to reflections of light. In the 20-minute video, Chamberlain demonstrates equations that help determine reflection, including predicted reflection and actual reflection. Also explored are the...

This lab activity, presented by John Chamberlain, demonstrates the measurement of diffraction and wavelengths from a laser. The first part of this 18-minute video shows the measurement of the Fraunhofer diffraction pattern from a pinhole, including the calculation of the needed distance between the...

This lab activity, provided by the Nanotechnology Applications and Career Knowledge Network (NACK) Center, teaches students about "oxidation and the furnace used to grow oxides." In the lab, students will "attempt to visually determine the oxide thickness of oxidized samples from a previous group,"...

This 7-page lab guide, created by the Nanotechnology Applications and Career Knowledge Support (NACK) Center at Pennsylvania State University, features an online laboratory activity that provides a demonstration and overview of the necessary procedures to operate the Lindberg tube furnace. During...
