In this science activity, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

In this equilibrium worksheet, students read about the factors that effect equilibrium in solutions such as the pressure of the solution, the temperature and the concentration of the solution. They answer three multi-part questions about...

In this chemical reactions worksheet, students are given fifteen unbalanced equations and they must identify the reaction types, the phases of the products, the signs that a chemical change occurred and the sum of the coefficients of the...

In this transition state theory worksheet, students read about chemical reactions and the theory for how chemical reactions proceed. They answer questions about the activated complex, the activation energy and the collision theory all...

In this spontaneous reactions worksheet, students read about entropy, enthalpy and Gibbs free energy. They complete a table with reaction conditions and determine if the reaction is spontaneous or not. They solve three problems about...

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter instructional activity students divide into groups and complete a lab experiment. 

Students study oxidation and define vocabulary pertinent to it.  In this oxidation lesson students make predictions and create experiments

Students explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the...

In this reaction coordinates worksheet, students are given a diagram of the reaction coordinate for a reversible catalyzed and uncatalyzed reaction. Students answer eighteen questions related to the diagram.

In this reactions worksheet, students give the equation for the overall reaction, identifying the catalyst in the equation. Students create graphs and write out the rate determining step. This worksheet has 4 graphs, 2 short answers, and...

In this chemical equilibrium learning exercise, students read about how additions to a system can shift the equilibrium. Students then apply the Le Chatelier's Principle to solve 5 problems.

Tenth graders write and balance chemical equations and make a PowerPoint presentation on synthesis reactions.

Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching...

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,...

The University of Siegen provides a lovely exothermic reaction shown by four large photos. Sodium peroxide and zinc powder with a touch of water.

A wonderfully complete primer on exothermic reactions in the context of chemical spills. Covers Reactions with Air or Water, Combustible Organics, Polymerization Reax, Decomposition, Corrosion, and much much more.

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

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...

[Free Registration/Login may be required to access all resource tools.] Explains the definition of an exothermic reaction, the role of energy, and examples of exothermic reactions.

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,...

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

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

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