In this general science worksheet, students find 32 science words reviewing states of matter and types of substances. Students may self correct by selecting the link at the bottom of the page.

Students determine the number of ionizable hydrogen's in an unknown acid and determine the equivalent weight of an unknown acid. They determine the enthalpy change for the ionization of an unknown acid.

Learners investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Young scholars explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

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.

Fourth graders determine the amount of energy required to melt ice using a calorimeter. They calculate the Molar Heat of Fusion of Ice.

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 science activity, students fill in the blank for 15 sentences about chemical energy. For example, "Chemical bonds hold_."

For this equilibrium worksheet, students determine the effect of adding or subtracting items from a reaction. Students determine the equilibrium constant for given reactions. This worksheet has 13 problems to solve.

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.

This site from the Interactive Learning Paradigms discusses and defines exothermic and endothermic reactions. Further information is given under the definitions along with several links to additonal information. An interesting site.

This lesson focuses on Exothermic and Endothermic Reactions. Exothermic reactions transfer energy to the surroundings. Endothermic reactions take in energy from the surroundings. It provides links to a video and a test.

In this activity, students will observe two chemical reactions. They will use an EasyTemp probe to determine the change in temperature and identify endothermic and exothermic reactions.

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,...

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

In this lesson plan on endothermic and exothermic reactions, students explore chemical reactions, energy transfer, and energy diagrams.

Scientific American magazine, in the person of Dr. Gerald R. Van Hecke, gives a wonderfully complete answer to this question. Complete with very many hot words for additional background. And a wonderful NASA launch photo.

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

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 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.

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.

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...

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