Students are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

This activity is designed for students to apply their knowledge of mathematics and physics to "real life" situations. Students are presented with the situation that they are on a camping trip and wish to know the wavelength emitted by a...

Students find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, student teams design and build their own spectrographs, researching and designing a...

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual...

Students create and decorate their own spectrographs using simple materials and holographic diffraction gratings. A holographic diffraction grating acts like a prism, showing the visual components of light. After building the...

Students use the spectrograph from the "Building a Fancy Spectrograph" activity to gather data about light sources. Using their data, they make comparisons between different light sources and make conjectures about the composition of a...

Analyze light by creating a CD spectroscope in this activity. See the whole spectrum of light with the spectroscope.
