Lesson Plan: Gases Unit Plan
In this lesson, students will investigate gases similar to how scientists learned about them “back in the day.” Students begin by investigating gas behavior, then they investigate gas density and use this to interpret Avogadro’s hypothesis that gases under the same conditions combine in simple whole number ratios.

We constructed a unit plan using AACT resources that is designed to teach the Gas Laws to your students.

In this simulation, students will investigate three of the fundamental gas laws, including Boyle’s Law, Charles’ Law and GayLussac’s Law. Students will have the opportunity to visually examine the effect of changing the associated variables of pressure, volume, or temperature in each situation. Also, students will analyze the gas samples at the particle level as well as manipulate quantitative data in each scenario. Finally students will interpret trends in the data by examining the graph associated with each of the gas laws. This lesson accompanies the simulation from the November 2015 issue of Chemistry Solutions.
