• Calorimetry, Heat, Specific Heat, Temperature, Exothermic & Endothermic, Scientific Method, Graphing, Experimental Design | High School

### Lab: Cool Science: Building and Testing a Model Radiator

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.

• Calorimetry, Heat, Specific Heat, Temperature | High School, Middle School

### Lab: Understanding Specific Heat

In this lab, students will get a general idea of specific heat by investigating the mixing of two liquids at different temperatures. In one case, the same liquids will be mixed, in another case different liquids will be mixed.

• Concentration, Molarity, Stoichiometry, Limiting Reactant, Chemical Change, Calorimetry, Heat, Temperature, Exothermic & Endothermic, Scientific Method, Enthalpy, Experimental Design | High School

### Lab: Less Than Zero

In this lab, students will investigate the endothermic reaction between baking soda and HCl. Students will consider stoichiometric ratios, molar concentrations, reaction scale, and calorimetry. The lab starts with a scripted reaction that uses given molar ratios, a glass beaker, and 2-M HCl. They will witness a temperature drop of about 5 to 8 C. Students then adjust the experiment so they can achieve a temperature drop of more than 20 C.

• Combustion, Accuracy, Dimensional Analysis, Measurements, Calorimetry, Heat, Specific Heat, Temperature, Exothermic & Endothermic, Heat of Combustion, Law of Conservation of Energy, Bond Energy, Error Analysis | High School

### Lab: How Much Energy is in Your Snack Food?

In this lab, students will find the amount of heat energy stored in foods and compare heat calories with food calories.

• Chemical Change, Heat, Temperature, Exothermic & Endothermic, Energy Diagrams | High School

### Lab: Exothermic and Endothermic Lab

In this lab, students determine whether mixing two chemicals is endothermic or exothermic. One is a physical change, one is a chemical change.

• Temperature, Heat, Exothermic & Endothermic, Law of Conservation of Energy | High School

### Activity: Endothermic & Exothermic Reactions

In this activity, students observe industrial-strength snap sticks and chemical cold packs and discuss processes of endothermic and exothermic reactions.

• Observations, Inferences, Calorimetry, Heat, Specific Heat, Temperature, Exothermic & Endothermic, Enthalpy | High School, Middle School

### Demonstration: Energy in Hot and Cold Packs

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.

• Observations, Physical Change, Solute & Solvent, Intermolecular Forces, Heat, Temperature, Exothermic & Endothermic, Saturated/Unsaturated/Supersaturated | High School, Middle School

### Lesson Plan: Particle Modeling of Hand Warmers

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.

• Observations, Chemical Change, Conservation of Mass, Chemical Change, Heat, Temperature, Exothermic & Endothermic | High School, Middle School

### Lab: Kitchen Reaction

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.

• Heat, Temperature, Exothermic & Endothermic, Le Châtelier's Principle, Establishing Equilibrium, Equilibrium Constants, Reaction Quotient | High School

### Demonstration: Le Châtelier’s Principle

In this demonstration, students will witness a system at equilibrium and apply different stresses to see how the equilibrium shifts.

• Concentration, Solute & Solvent, Colligative Properties, Calorimetry, Heat, Specific Heat, Temperature, Freezing Point Depression, Error Analysis | High School

### Lesson Plan: The Hot and Cold of it All

In this lesson students will analyze the effectiveness of different brands of antifreeze/coolants and their ability to protect an engine in cold climates. Students will conduct a lab investigation to examine the freezing point depression in samples that have been diluted with distilled water. Students will also determine the specific heat capacities of antifreeze/coolant products as compared to pure water and explain how it relates to thermal energy transfer in the internal combustion engine.

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

### Lab: Designing Exothermic and Endothermic Reactions

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.

• Temperature, Chemical Change, Interdisciplinary, History, Heat, Temperature | Middle School, High School

### Lab: Greenhouse Gas Simulation

In this lab, students will create two simulations of the Earth’s atmosphere. They will compare a control model with a one that has an increased presence of carbon dioxide gas in order to analyze how this effects temperature. They will also complete research in order to learn more about the makeup of the Earth’s atmosphere.
