1 – 9 of 9 Classroom Resources

• 

  Chemical Change, Exothermic & Endothermic | Elementary School, Middle School

  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.

  Exothermic & Endothermic, Heat, Temperature, Classification of Reactions | Middle School, High School

  Lab: Determining Endothermic and Exothermic Reaction Mark as Favorite (19 Favorites)

  In this lab, students will analyze evidence to determine if a chemical reaction releases energy and can be classified as an exothermic reaction or if it absorbs energy and can be classified as an endothermic reaction.

  Exothermic & Endothermic, Classification of Reactions | Middle School, High School

  Activity: Simulation Activity: Energy Changes in Chemical Reactions Mark as Favorite (27 Favorites)

  In this simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Through the use of this simulation students will have the opportunity to compare how energy is absorbed and released in each reaction. Additionally, students will make a connection between the standard energy diagrams associated with each reaction type.

• 

  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.

• 

  Conservation of Mass, Exothermic & Endothermic | High School, Middle School

  Lab: Kitchen Reaction Mark as Favorite (6 Favorites)

  In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.

• 

  Exothermic & Endothermic | High School, Middle School

  Demonstration: Energy in Hot and Cold Packs Mark as Favorite (7 Favorites)

  In this demonstration, students will observe temperature changes in chemical hot and cold packs and discuss processes of endothermic and exothermic changes. They will also see that common household products can be used to make a hot and cold pack.

• 

  Exothermic & Endothermic, Physical Change, Temperature, Freezing Point, Boiling Point | High School, Middle School

  Demonstration: Energy Mark as Favorite (2 Favorites)

  In this demonstration, students will observe the exothermic and endothermic properties of state changes of substances with different freezing and boiling points.

• 

  Exothermic & Endothermic, Chemical Change, Heat, Temperature, Classification of Reactions | Middle School, High School

  Lab: Designing Exothermic and Endothermic Reactions Mark as Favorite (7 Favorites)

  In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.

• 

  Exothermic & Endothermic, Physical Change | High School, Middle School

  Lesson Plan: Particle Modeling of Hand Warmers Mark as Favorite (9 Favorites)

  In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.
