Students are introduced to the scientists that made the instruments to study the behavior of gases.

The main menu displays the scientists and their gas law formulas. It also contains a web links button to find resources on the web.

In Boyle's Law students drag weights on a cylinder they have filled with a gas and record pressure, volume and temperature. Graphing pressure vs. volume helps them discover that these two variables are inversely proportional.

No science lesson is complete without interesting facts about the lives of the scientists.

In Charles' Law students manipulate the temperature of a gas and view the change in volume. Graphing their data shows them that the two variables are directly proportional (but only if their temperature is converted to Kelvin).

Throughout the program students work out gas law problems. The program shows them how to rearrange formulas to solve for a variable.

In one lesson the pressure gauge breaks when the student clicks on it too hard. They are then forced to calculate the new pressure using Boyle's Law.

Gay-Lussac's Law is covered in the same manner as Boyle's and Charles' Laws: manipulation of a gas and then calculations using formulas.
