  Demonstration: Giant Toothpaste Mark as Favorite (6 Favorites)

  In this demonstration, students will identify factors that indicate a chemical change has occurred while observing the production of giant toothpaste. This reaction uses simpler materials than those that are often used in the typical high school version of the Elephant’s toothpaste demonstration.

  Lab: Super Suds Mark as Favorite (2 Favorites)

  In this lab, students will investigate an endothermic chemical reaction by combining baking soda, hand soap and citric acid. The students will be tasked with differentiating between chemical and physical changes during this experiment.

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

  Video: The Internal Combustion Engine Video Mark as Favorite (7 Favorites)

  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.

  Demonstration: Comparing Chemical Reactions Mark as Favorite (2 Favorites)

  In this demonstration, the teacher will perform two chemical reactions, one will be between acetic acid (vinegar) and sodium bicarbonate (baking soda) and the other will be between Alka-Seltzer and water. Both reactions will produce gas and will be conducted in a Ziploc bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical change. Students will also determine that these are both endothermic reactions based on their observations.
