This site provides an overview of the role of energy in chemical reactions.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...

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...

Observe that chemical reactions follow the pathway the uses the least amount of energy in this simulation.

Learners will participate in a guided inquiry activity using manipulatives to learn how to balance chemical reactions. This activity was developed in cooperation with Michelle Holdbrooks at Thompson High School...

Because atoms are neither created nor destroyed in a chemical reaction, the total mass of products in a reaction must be the same as the total mass of the reactants.

Students will perform chemical reactions for the class to observe evidence of reactions and write equations to describe the reaction.

In this activity, students carry out a chemical reaction in which two reactants (baking soda and hydrochloric acid) produce three products (sodium chloride, carbon dioxide gas, and water) and determine that the solid product (sodium...

A quick look into how to control the amount of products in chemical reactions.

This lesson focuses on predicting chemical reactions using The Group 1 elements in the Periodic Table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with air and water. It provides...

A detailed description of the different types of chemical reactions in organic and inorganic chemistry.

Students observe and investigate how a catalyst increases the rate of a chemical reaction while not becoming part of the products of the reaction.

The guided inquiry activity enables learners to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products...

Observe reactions that produce gases in this lab activity! Students observe chemical changes as they evaluate the amount of gas produced. This lab activity includes both student and teacher instruction sheets.

Use these demostration video clips to help understand the energy changes in some chemical reactions.

A site discussing chemical reactions in chemistry including reaction rate, types of reactions, reagents, reactants, catalysts, and inhibitors.

Explanation of Noble gases and of how atoms attempt to fill their outermost valence shells for stability.

Explains the use of a reaction table when analyzing chemical equilibrium and presents a virtual experiment where the equilibrium constant of a chemical reaction is determined for different scenarios. Requires Java.

[Free Registration/Login may be required to access all resource tools.] Students describe how the elementary steps of a chemical reaction combine to produce the overall reaction mechanism, and identify intermediates and catalysts when...

In this science fair project, experiment with the role temperature plays in the rate at which UV beads lose their color. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

In this experiment, you will determine the rate law and confirm the mechanism of the reaction between cyclohexanone and iodine. Requires Java and QuickTime plug-ins to access some features.

[Free Registration/Login may be required to access all resource tools.] Students explore mass relations between reactants and products for a given chemical process, and practice balancing chemical equations.

Use chemical formulas to visualize how chemical equations are balanced.

This lesson begins with a story about rescuing reptile eggs from a new construction site. Using the story as motivation, students are presented with an engineering design challenge: Build a portable device which can warm, support, and...
