Demonstration: Exploring Gas Solubility
In this demonstration, students will explore how changes in pressure and temperature affect the solubility of a gas in an aqueous solution. In addition, students will have the opportunity in a post-demonstration reflection activity to practice using data (in this case their demonstration observations) to make evidence based claims.
-
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.

Gas Laws, Pressure, History, Volume | High School, Middle School
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.

Lab: Observing Density of Gases and Liquids
Students will learn about and discuss the behavior of a gas using examples of convection and an optional teacher-led demonstration. Students will then participation in a lab where they will investigate water currents by observing the results of mixing colored warm water with room temperature water. The lab will be followed by a discussion about the molecular activity of the water mixture.

Demonstration: EGGsperiment
In this demonstration, students will learn how temperature change affects air pressure, while observing an egg getting sucked into a bottle without being touched!
-
Temperature, Heat, Temperature | Elementary School
Demonstration: Global Warming in a Jar
In this demonstration students will learn about the cause and effects of global warming. Students will research about global warming, while also comparing it to a demonstration. This will help students to better understand the effects that temperature change can have on the planet.

This video tells the story of Robert Boyle, a great chemist and discoverer of Boyle's Law, which describes the relationship between pressure and volume of a gas.
-
Temperature, Gas Laws, Pressure, Kinetic Molecular Theory, Volume | High School, Middle School
Animation: Gases Animation

Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School
Demonstration: Investigating Gas Density
In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.
