Explains what an exothermic chemical reaction and is and gives examples seen in everyday life.

Explains the differences between endothermic and exothermic reactions and the role thermodynamic potentials play in them. Examples from nature are also provided.

A nice juxtaposition of endo- and exothermic reactions. Outlines two demonstrations. Barium hydroxide, sodium acetate, ammonium nitrate, ammonia.

This lesson explains the difference between endothermic and exothermic chemical reactions. It is 4 of 4 in the series titled "Endothermic/Exothermic Reactions."

This lesson explains the difference between endothermic and exothermic chemical reactions. It is 2 of 4 in the series titled "Endothermic/Exothermic Reactions."

A demonstration to introduce energy changes during reactions, and to promote discussion regarding exothermic and endothermic reactions, enthalpy, spontaneity, system, and surroundings.

Assess your ability to distinguish between exothermic and endothermic chemical reactions with this interactive multiple choice quiz. Receive immediate feedback to your answers.

Students work through this inquiry-based lab while observing and recording the heat processes taking place. The lab demonstrates exothermic and endothermic processes, and then challenges the students to predict the outcome of an unknown...

This lab allows students to collect data for different types of reactions: endothermic and exothermic. Students compile the data, create graphs and answer questions concerning their lab experience.

Equations illustrating both endothermic and exothermic reactions, with energetics involved.

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.

This lesson explains the difference between endothermic and exothermic chemical reactions. It is 3 of 4 in the series titled "Endothermic/Exothermic Reactions."

Make your own sidewalk chalk, and learn about chemical reactions. During the procedure, feel the heat as energy is released in an exothermic reaction.

Science experiment shows how yeast mixed with hydrogen peroxide creates not only foam but an Exothermic Reaction.

Students will conduct two chemical reactions: endothermic and exothermic. They will see an animation that shows that it takes energy to break bonds and that energy is released when new bonds are formed, and use that animation to explain...

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...

In this chemistry science fair project, students will investigate how pH levels affect the rate of a common form of corrosion, called rusting. The Science Buddies project ideas are set up consistently beginning with an abstract,...

Determine how the starting temperature affects crystal growth and heat generation of a hand warmer in this chemistry science fair project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective,...

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 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.

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