Reflected Light
The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities.

Rainbows of Light: The Visible Light Spectrum
Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson then explains wavelength using a rope to make waves.

Reflection and Refraction
What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

Radioactive Pollution
Radioactive pollutants can enter the body through ingestion, inhalation, absorption, or injection. The last lesson in a series of 36 introduces pupils to radioactive pollution. They study its sources, both natural and man-made, its...

Mass and Volume
Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Com Padre Digital Library: Open Source Physics: Compton Effect
Simulation demonstrating the Compton Effect; how light is scattered off an electron. Adjust the angle of the scattering to see how Compton's equation can be used to predict the angle of the photon that is scattered.

Com Padre Digital Library: Open Source Physics: Multiple Slit Diffraction Model
Simulation that shows the diffraction of light through single or multiple slits. Simulation allows modification of the number of slits, slit width, slit separation, and the wavelength.
