Kaleidoscope
Source Institutions
In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.
Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.
What is Nanotechnology?
Source Institutions
In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Cardboard Opaque Projector
Source Institutions
In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
Iridescent Art
Source Institutions
This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.
Cardboard Box Camera Obscura
Source Institutions
In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.
Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
Tissue Paper Spray Art
Source Institutions
In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.
High Tech Fashion
Source Institutions
In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.
