Classroom Resources: Reactions & Stoichiometry

1 – 4 of 4 Classroom Resources

• 

  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.
