Light! How do we see? What makes light? Find out everything you need to know through the Q&As on this site.

An interactive tool where students can create a model of a greenhouse and use a light sensor to measure the amount of light it receives from a lamp at various times of the day. Temperature is also measured. Data is plotted on graphs,...

Sun tanning has a bad rap right now. Use a personal ultraviolet monitor to measure the UV index to prevent getting a sunburn. With this science fair project you will create a chart showing the UV ray measurement at different times of the...

What is light energy? Here we'll learn about the properties of light and how pigments such as chlorophylls absorb light energy.

Here is a large collection of simple science class activities for understanding the physics of light.

Physiclips thoroughly presents mechanics concepts about light with animations and film clips. Learn about light and color, wavelengths, speed of light, electromagnetic waves, Young's experiment, and photons.

Why is light important? Play this interactive night light game with PEEP and observe why we need light to see objects. Also included are teaching tips.

What is light? A detailed examination of what creates light, light spectrums, scientists' discoveries, and colored graphics. Appropriate for the older student or adult researcher.

How light waves demonstrate their wave nature by reflection, refraction, and diffraction.

The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.

Who uses light to communicate? Go from sea to shining sea as we visit a lighthouse, board a Navy ship, and take a stroll on the red carpet! Learners will investigate different ways of communicating with light and at the end of the lesson...

How does a one-way mirror work? Though most everyone knows that one-way mirrors exist, having students model how they work turns out to be a very effective way to develop their thinking about how visible light travels and how we see...
