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. |
