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...

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

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...

Young scholars investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

In this emission spectra worksheet, young scholars use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.

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

In this physics worksheet, students observe white light through a spectroscope and describe what they see. Then they observe fluorescent light with the spectroscope and describe what they see. Students also describe why it is important...

High schoolers 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...

Complete this interactive tutorial and learn about interpreting the infrared spectrum ("I" "R") that provides information about the functional groups in a molecule. Included are 12 labs and a quiz.

A very lengthy page from friesian.com discussing Bohr's theory of electronic energy levels and the explanation of commonly observed atomic emission line spectra. The concept of a photon and Einstein's observation of the photoelectric...
