  • Combustion, Heat, Exothermic & Endothermic, Heat of Combustion | High School, Middle School, Elementary School

    Video: The Internal Combustion Engine Video

    This video investigates both the mechanical and the chemical processes used in the internal combustion engine, as well as the history and evolution of the combustion engine.

  • Catalysts, Reduction, Combustion, Redox Reaction, Activation Energy, Oxidation | High School, Middle School, Elementary School

    Video: Catalytic Converters Video

    This video investigates the role of a catalytic converter and its corresponding chemical reactions within a vehicle. Students will learn about both oxidation and reduction reactions and how they, in combination with a catalyst, can impact the molecules released in a car’s exhaust.

  • 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.

  • Observations, Phase Changes, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.
