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

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

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

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
