Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

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 simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

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

In this activity, learners overlap the three primary colors to see how all other colors are made.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

This is an activity exploring color and color mixing.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this activity, learners make a Benham Top to explore visual illusions and optics.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

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