  Density, Density, Chemical Change, Observations, Chemical Change, Combustion | Elementary School, Middle 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.

  Gas Laws, Kinetic Molecular Theory, Ideal Gas, Temperature, Volume, Pressure, Density, Density, Experimental Design, Scientific Method | High School, Middle School

  Activity: Hot Air Balloon

  In this activity, students use their knowledge of Charles’ law to build a hot air balloon and evaluate its design.

• 

  Chemical Change, Density, Chemical Change, Density | Elementary School, Middle School, High School

  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, Middle 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.

  Molecular Motion, Density, Physical Properties, Density, Gas Laws, Ideal Gas, Temperature, Pressure, Volume | Middle School, High School

  Simulation: Density

  The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.
