Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth instructional activity of an 11-part series. Individuals then...

This lab is designed to allow students to look at the factors affecting the location of different colors formed by diffraction grating.

This lab is designed to allow students to look at the relative proportions of different wavelengths of light that are emitted by stars at different temperatures.

This lab is designed to have students investigate the relationship between the speed of a wave, the frequency of the wave and the wavelength of the wave. Students can vary wave speed and frequency. Each of these should be varied while...

This lab is designed to allow students to look at the factors affecting the angle at which constructive interference occurs for waves passing through a two slit diffraction grating. This video helps explain the problem:...
