Classroom Resources: Gases
1 – 3 of 3 Classroom Resources
Density, Temperature, Density, Molecular Motion | Elementary School
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 | Elementary School, Middle School
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, Chemical Change, Density, Chemical Change | Elementary School, Middle School, High School
In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.
