Classroom Resources: Reactions & Stoichiometry

1 – 7 of 7 Classroom Resources

• 

  Classification of Reactions, Chemical Change, Balancing Equations, Acid Base Reactions, Combustion | Middle School, High School

  Animation: Classifying Chemical Reactions Animation

  This animation explores some of the ways to classify different types of chemical reactions. It covers synthesis (combination), decomposition, single replacement (single displacement), double replacement (double displacement), combustion, and acid-base neutralization reactions. This animation was featured in the November 2020 issue of Chemistry Solutions. **This video has no audio**

• 

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

• 

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

• 

  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.

• 

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

  Demonstration: The Jumping Flame

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

• 

  Combustion, Chemical Change, Catalysts, Acid Base Reactions, Chemical Change, Balancing Equations, Classification of Reactions, Observations, Chemical Change | High School, Middle School

  Demonstration: Stop & Go Gases

  In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame. They will also be introduced to the concept of catalysts. This demonstration could also be used as an opportunity to practice writing and balancing equations and classifying chemical reactions.

• 

  Observations, Combustion, Phase Changes, Experimental Design, Scientific Method | High School, Middle School

  Lab: Observing a Candle

  In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.
