In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

High schoolers investigate the absorptivity of different colored food dyes. For this chemistry lesson, students explain how we see colors. They construct a graph of absorbance comparred with wavelength using experimental data.

Young scholars examine the spectra with the use of light while constructing their own spectroscope. They make observations about the colors and visible wavelengths of light and then conduct classroom discussions. As an extension students...

Twelfth graders research physical and chemical methods used in authenticating paintings (e.g., ultraviolet fluorescence and spectroscopy, infrared spectroscopy and reflectography, X-ray diffraction, microscopy, pigment analysis, and gas...
