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.
Discovery Education
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...

Take-Home Midterm Exam #3, Part A
Let your physics learners take this electromagnetic radiation exam home to show what they know. You could also use it in class or assign it as a review. The content covers concepts pertaining to color, wavelength, frequency, refraction,...

Stations of Light
Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. Students investigate...

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...
Curated OER
Reflect and Refract
Pupils explore light. In this properties of light lesson, students define the terms refract, reflect, and diffract after listening to the teacher's description. Pupils listen to the book Light Magic and observe a spoon in a glass of...

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.

Chemical Sleuthing
Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.

THE MANY COLORS OF SUNLIGHT
Students examine rainbow components, spectral colors, colors perceived by the eye, hot solids, glowing rarefied gas, absorption, that light is a wave, and optics.

Physical Optics: The Wave Nature of Light
Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...

Optical Simulation of a Transmission Electron Microscope
Don't have an electron microscope? Have your classes build the next best thing! A hands-on instructional activity asks scholars to build a model of Transmission Electron Microscope (TEM). They then use their models to identify the...

Check Out Lights and Shields with Beads
Students explore Ultraviolet detecting beads and conduct several investigations with them. In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings.
Curated OER
Examining Spectra
Students examine the spectra with the use of light while constructing their own spectroscope. They make observations about the colors and visible wavelengths of light and then conduct classroom discussions. As an extension students read...
