Classroom Resources: Reactions & Stoichiometry
1 – 4 of 4 Classroom Resources
Heat of Combustion, Heat, Exothermic & Endothermic, Combustion | Elementary School, Middle School, High School
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.
Reduction, Oxidation, Redox Reaction, Catalysts, Activation Energy, Combustion | Elementary School, Middle School, High School
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.
Density, Density, Chemical Change, Observations, Chemical Change, Combustion | 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.
Chemical Change, Phase Changes, Combustion, Observations | Elementary School, Middle School
In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.
