Density, Combustion, Lab Safety | 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.

Lab: Gas Density and Relative Molecular Mass
In this lab, students will quantitatively determine the densities of four gases.

Demonstration: Fire Extinguisher
In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.

Demonstration: Qualitative Look at Gas Density
In this demo, students witness three types of gases and observe their relative densities to air.

Gas Laws, Matter, Density, Density, Temperature, Pressure, Volume, Graphing, Observations, Measurements | High School
Lab: Pressure Bottle
In this lab, students determine the relationship between volume and pressure of a gas and its temperature and address the common misconception that air does not have mass or density.

Demonstration: Comparing Gas Density
In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. 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 candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.
