In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners create a straw oboe to explore sound and pitch.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this online activity, learners test their ability to hear different frequencies and compare their frequency range with the frequency range of other animals and insects.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.
