Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!Add to list Details
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
The Ripple TankAdd to list Details
In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
Exploring the Nanoworld with LEGO Bricks: Probing the Structure of Materials at the Nanoscale
In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.
Diffraction Between Wax BlocksAdd to list Details
In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.
Splitting White LightAdd to list Details
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
Spots, Lines and LasersAdd to list Details
Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.
How Thick is Your Hair?Add to list Details
In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
Glow in the DarkAdd to list Details
Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
CD SpectrometerAdd to list Details
In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.
Rutherford's Enlarged: A Content-Embedded Activity to Teach about Nature of Science
This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.
Interference in a Ripple TankAdd to list Details
In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
Light and Sound
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
Reflecting on Diffraction
With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.
