In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
