Diffraction Demystified
Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks.

Through the Looking Glass
Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

Patterns and Fingerprints
Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

Building Spectroscope
Given specific materials, scholars follow a set of instructions to build and calibrate their very own spectroscopes. After construction, they test the scope for accuracy and make modifications where necessary.
