  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.

  Calorimetry, Exothermic & Endothermic | High School

  Lab: Cool Science: Building and Testing a Model Radiator Mark as Favorite (5 Favorites)

  In this lab students construct a model of a car radiator to investigate parameters that lead to efficient cooling. Students investigate multiple variables as they experiment with various radiator designs. This lesson focuses on thermochemistry calculations and engineering practices.

  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.

  Chemical Change, Exothermic & Endothermic, Acid Base Reactions, Chemical Change | Elementary School

  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.

  Lab: Observing a Chemical Reaction Mark as Favorite (4 Favorites)

  In this lab, students will practice making careful observations and measurements while witnessing a chemical change.

  Exothermic & Endothermic, Classification of Reactions

  Simulation: Energy Changes in Chemical Reactions Mark as Favorite (0 Favorites)

  In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.
