In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners stain fabrics--on purpose!

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

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.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.
