This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

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 make a photographic image—without a camera!

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 optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

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

This is an activity about turbidity, or the amount of sediment suspended in water.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.
