Density, Lab Safety, Combustion | High School
Demonstration: Density of Gases and Particle Diagrams
In this demonstration, students will observe the teacher carry out two combustion reactions. First the teacher will burn a small sample of propane gas in a beaker. Next the teacher will burn a small sample of methane gas. Students will create particle diagrams in order support their explanation and model their observations as they improve their understanding of gas density.

Kinetic Molecular Theory | High School
Demonstration: Diffusion of Particles
In this demonstration students will experience diffusion, and then model the process of diffusion of microwave popcorn “flavor particles” in a room filled with still air.
-
Gas Laws, Pressure, Volume | High School
Lab: Deriving the Gas Laws
In this lab, students will investigate the relationships of the variables related to gases. They will draw particle diagrams and derive equations to express these relationships. They will then combine these relationships to derive the combined gas law and the ideal gas law. Finally, they will use the molar volume of a gas at STP to derive the ideal gas constant, R.
-
Gas Laws, Pressure, Kinetic Molecular Theory, Volume | High School
Demonstration: Inflate and Shrink Wrap a Student
In this demonstration, students will observe two situations. First a student will be lifted off the desk as other students blow air into straws connected to a garbage bag in order to inflate it. Secondly, the class will observe a garbage bag shrink wrapping a student as a vacuum removes air from the bag.

Activity: Robert Boyle Video Questions
In this activity, students will watch a video and answer questions about Robert Boyle. They will learn about his impact in chemistry, including Boyle’s Law which describes the relationship between pressure and volume of a gas.
-
Temperature, Kinetic Molecular Theory, Heat, Temperature | High School, Middle School
Lab: Mega Marshmallows
In this lab, students will investigate the Kinetic Molecular Theory and particle motion while experimenting with a marshmallow. Students will observe how an increase in kinetic energy will cause particles to increase in motion. This concept will be extended into a discussion about additional real world thermal expansion examples.
