Where does bad light end up? In a prism! The presentation covers light, mirrors, lenses, and the structure of the eye. It also provides explanations of reflection, refraction, concave and convex mirrors and lenses, and a comparison of...

Here's a colorful resource about spectra. An intriguing lesson plan teaches pupils about diffraction grating and about absorption and emission spectra. They see how to represent spectra using line plots and try out this skill in a...

Scholars play with an image's color and brightness to predict how tyrannosaurus rex's skin, feathers, and eyes would have appeared. Information and real-world pictures shed light on what evidence guides our assumption of how a...

Horses come in all shapes and sizes, but all belong to the same species. Young scholars explore the different traits and connect the information to genetic modification. The interactive gives them the option to read about 18 different...

This animation discusses light and the properties of light in a storybook format. The animations cover the colors of the rainbow (ROYGBIV) along with prisms, light waves, reflection, and refraction.

Why do we see certain colors? This interactive animation demonstrates the concept of the visible spectrum, and how we see the different colors of the rainbow.

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.
