In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

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.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this activity, learners build a bird feeder or feeders to attract birds for observation.

In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.
