[Free Registration/Login may be required to access all resource tools.] Explains chemical property and chemical 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...

In this 9th grade physical science guided inquiry, students will work in pairs to discover the indicators of chemical reactions. Each pair of students is assigned either an exothermic or endothermic reaction. Based on their observations,...

Here's a full and understandable discussion of Reaction Rates and Equilibrium.

[Free Registration/Login may be required to access all resource tools.] Covers the law of conservation of energy and how energy is conserved in chemical reactions.

[Free Registration/Login may be required to access all resource tools.] Describes the law of conservation of energy and how energy is conserved in chemical reactions.

Understand chemical reactions by learning about enthalpy and entropy.

Explains what an endothermic reaction is and gives four everyday examples.

A quick, five question review over various concepts of chemical reactions.

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

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,...

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.

Find out what entropy and enthalpy have to do with a spontaneous chemical reaction. [3:44]

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

This lesson will give an overview of different types of chemical 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.

Observe an explosion on a molecular level. Understand how explosions can do work.

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

A simple lab activity that allows good data collection on heat of solution.

[Free Registration/Login may be required to access all resource tools.] Definition of activation energy and why all chemical reactions require it.

Students 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 mixture....
