Calorimetry, Heat, Hess's Law, Enthalpy, Error Analysis  High School
Lab: Utilizing Hess's Law
In this lab, students will use a coffee cup calorimeter to collect data that will allow them to calculate ∆H for two reactions. The first reaction, between sodium bicarbonate and hydrochloric acid is endothermic. The second, between sodium carbonate and hydrochloric pressure, is exothermic. They will then use their experimental values and Hess’s Law to determine ∆H for the decomposition of sodium bicarbonate, compare their calculated value to the theoretical value, and calculate the percent error. This resource includes a prelab presentation and sample calculations.

Entropy, Gibb's Free Energy , Enthalpy  High School
Lab: Thermodynamics Escape Room
In this lab, students are presented with an escape room scenario that challenges them to complete three tasks in order to escape from an old, mysterious Gothic house. Students are given access to a small assortment of chemicals, and standard lab equipment. They must determine which chemicals and equipment will help them to light a tap light without touching it, free a key from a block of ice without using a conventional heat source, and free a lock that is buried in a pile of glue.

Entropy, Exothermic & Endothermic, Gibb's Free Energy , Enthalpy, Spontaneous vs. Nonspontaneous Reactions  High School
Lab: Investigating Enthalpy and Entropy
In this lab, students will be able to observe and measure energy changes during the formation of solutions. The students should be able to explain and describe these changes in terms of entropy, enthalpy and free energy.

Calorimetry, Heat, Entropy, Specific Heat, Temperature, Exothermic & Endothermic, Hess's Law, Gibb's Free Energy , Enthalpy, Energy Diagrams  High School
Lesson Plan: Thermochemistry and Thermodynamics Unit Plan
The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach thermochemistry and thermodynamics to your students.

Catalysts, Entropy, Equilibrium Constants, Enthalpy, Activation Energy, Energy Diagrams, Reaction Quotient, Spontaneous vs. Nonspontaneous Reactions  High School
Lesson Plan: Making Connections in Kinetics, Equilibrium and Thermochemistry
In this lesson students will understand the connections between the equilibrium constant (K) and the reaction quotient (Q) as well as how they determine the favorability of a reaction. Additionally students will be able to determine if a reaction is kinetically favored or thermodynamically favored.

Entropy, Gibb's Free Energy , Enthalpy  High School
Lesson Plan: Enthalpy and Entropy as Driving Forces
In this activity students observe various chemical and physical processes to qualitatively predict and explain the signs of ∆S and ∆H. Based on their observations, they will predict the sign of ∆G and will determine the driving force of the process. Students will then calculate ∆S, ∆H and ∆G. This lesson focuses on thermochemical predictions, calculations and explanations.

Exothermic & Endothermic, Hess's Law, Enthalpy  High School
Lesson Plan: Hess's Law
In this lesson, students learn about the concepts of Hess's Law and how to solve problems involving them.

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 2M 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.

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.

Gas Laws, Catalysts, Combustion, Stoichiometry, Limiting Reactant, Enthalpy, Activation Energy, Energy Diagrams, Experimental Design  High School
Lab: Launching Rockets
In this lab, students create a stoichiometric mixture of hydrogen and oxygen gases to launch a soda bottle rocket.
