Given descriptions, diagrams, scenarios, or chemical symbols, students will calculate the energy changes and identify exothermic and endothermic reactions.

Students can use TI graphing calculators and data collection to find equations of lines using slope-intercept format and graph.

[Free Registration/Login Required] Explore endothermic and exothermic processes by making a cold pack or hot pack.

In this activity, students examine the size, mass, and growth rates for three species of fish. They interpolate and extrapolate from best-fit models. Students compare the growth rates of endothermic and exothermic animals.

The teacher will conduct the whoosh bottle demonstration to engage students. The class will then begin discussion of endothermic and exothermic physical and chemical changes. The students will then conduct the Science in Motion lab...

[Free Registration/Login may be required to access all resource tools.] Students learn about the role of activation energy in a chemical reaction, and the difference between endothermic and exothermic reactions.

Young scholars will create an endothermic chemical reaction by making ice cream. They will observe, describe, and measure the ingredients. After making ice cream, students will measure the temperature of the ice cream and the ice/salt...

This resource provides a physical reaction. Hydrous and anhydrous calcium chloride react with water to produce physical exothermic and endothermic reactions.

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

This lesson focuses on heat energy changes in chemical reactions. Exothermic reactions transfer energy to the surroundings. Endothermic reactions take in energy from the surroundings. It also offers links to a video and a test.

In this chemistry lab, students investigate two types of reactions and answer questions relating to exothermic and endothermic reactions.

This article from the Florida State University provides an excellent explanation of WHY Hess's Law works and examples of how to use the law. Common mistakes are identified and explained.
