Classroom Resources: Gases

1 – 7 of 7 Classroom Resources

• 

  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.

• 

  Density, Temperature, Density, Molecular Motion | Elementary School

  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.

  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.

• 

  Density | High School

  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.

• 

  Density, Density | Middle School, High School

  Demonstration: Qualitative Look at Gas Density

  In this demo, students witness three types of gases and observe their relative densities to air.

  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.
