Spectroscope
Learners examine how to apply conservation of energy and properties of matter to a spectroscope. In this energy activity students build their own spectroscope and observe three kinds of spectra.

The Grating Spectrometer; Light and Wavelengths
Students create a paper model that demonstrates wave interference for 3 wavelength from 2 sources. In this light and wave activity, students use a real spectrometer and observe and measure the wavelength of spectral lines. Students then,...

Spectral Classification of Stars
In this spectral composition of stars worksheet, students use data collected by a spectroscope to compare the stellar spectra to a standard for 5 stars. Students compare the spectral lines to the temperatures of the stars.

Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. For this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
Curated OER
Overhead Spectroscopy
Students explore the relevance and importance of data collection and analysis techniques that use different parts of the electromagnetic spectrum. They observe the basic concepts of the visible electromagnetic spectrum and the...

Constructing a Spectroscope
Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
Curated OER
Simple Spectroscope
Students make a spectroscope out of simple materials and are expected to view as many different light sources as possible to see the whole spectrum.
Curated OER
Analytical Spectroscope
Students using a spectroscope view different substances when heated with electricity.
