Curated OER
Sleuth Rays
Learners conduct a close examination of the atom's electrons, and discover how to theorize the energy levels, observe the brightness of light, classify colors, and measure temperature.
Curated OER
Chemical Sleuthing
Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.
