Wave Interference
Why did the waves get into a fight? They were tired of each other's interference. Scholars observe the wave patterns from dripping water, sound waves, and light waves. They vary the spacing, build barriers, and increase the number of...

Moire Patterns
By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference.

Stow Lake
Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...
Exploratorium
Soap Film Painting
If you are up for constructing a wooden frame, you can do this demonstration of the interference patterns when light reflects off of layers of soapy film. Both constructive and destructive interference can be seen as evidenced by the...
Exploratorium
Bridge Light
An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

Seeing Interference Fringes with a Telescope
Students construct an interferometer using a simple telescope. In this physics lesson, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

Sometimes You Behave Like a WAVE, Sometimes You Don't!
Electromagnetic radiation behaves like both a wave and a particle. Help classes explore this concept through a lab investigation. Young scientists create optical interference patterns on a glass slide using a carbon layer. They analyze...
Cornell University
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.

Bubbles and Biosensors
Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...

The Marina
Breakwaters offer marinas and beaches protection from large ocean waves, but how do they work? Scholars observe wave patterns and wave amplitude during the simulation. They control the number of openings, width of openings, distance...
Curated OER
Frozen Film
Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.

Show Me the Genes
Give your class a chance to show what they know. In the last installment of a seven-part series, pupils summarize and review what they have learned in the series. They present their solutions for creating a biosensor to detect cancer...

Inferences of Waves
Building on the previous lesson, scholars use Slinkies to create standing waves. They graph waves on a calculator and then apply their knowledge to both sound and light waves. This is the fourth in a series of nine lessons.

What Does Light See?
The second installment of a seven-part series focuses on the refraction of light and how it affects the colors we see. Learners consider how this concept connects to biosensors for cancer detection.

Using the Sounds of Words Reading Task
Young readers demonstrate phonemic awareness in words and blends, and recognize 100 high-frequency words. Use a nursery rhyme to point out rhyming words, and change the words by putting a new letter at the beginning. Each learner will...
Dick Blick Art Materials
Art Press Tools
Kids cast their own plaster tools to stamp image impressions and textures for tiles, pictures frames, and other works of art. Young artists can even create their own watermark to label their stuff.
