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

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

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

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.
