  Lab: The Disappearing Color Mark as Favorite (5 Favorites)

  In this lab, students will create a solution to observe a chemical change between food coloring in water and bleach. They will also develop the process skills of predicting, observing, and measuring temperature.

  Demonstration: Plop & Fizz Investigation Mark as Favorite (1 Favorite)

  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.

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

  Video: Catalytic Converters Video Mark as Favorite (31 Favorites)

  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.

  Lab: To What DEGREE Does it Matter Mark as Favorite (0 Favorites)

  In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.
