In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
