  Chemical Change, Reaction Rate, Reaction Rate, Phase Changes | Elementary School

  Demonstration: Plop & Fizz Investigation Mark as Favorite (0 Favorites)

  In the demonstration the teacher will perform a reaction between water and Alka-Seltzer in order to generate the release of carbon dioxide. Students will observe the chemical reaction, while timing the release of carbon dioxide and observe 3 states of matter. This will be repeated 3 times, each time increasing the number of tablets used.

  Reaction Rate, Activation Energy, Catalysts, Combustion, Reaction Rate | High School

  Demonstration: Rates of Reactions Mark as Favorite (7 Favorites)

  In this series of demonstrations, students will be introduced to factors that affect the rates of chemical reactions. They will observe and record their observations, while also describing the rate-influencing factor for each demonstration as well as evidence supporting whether or not the reaction rate was increased or decreased by the factor.

  Classification of Reactions, Chemical Change, Catalysts, Observations | Middle School, High School

  Demonstration: Catalyst in Motion Mark as Favorite (6 Favorites)

  This demonstration allows students to visualize how a catalyst can impact a chemical reaction. Students will also identify the products of a decomposition reaction, as well as determine if the reaction was endothermic or exothermic based on their observations.
