Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
Diffraction Between Wax Blocks
Source Institutions
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.
Moiré Patterns
Source Institutions
In this activity about light and perception, learners create and observe moire patterns.
Interference in a Ripple Tank
Source Institutions
In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.
