In this carbon dating learning exercise, students write and illustrate a comic strip describing the entire process of C-14 dating. Then students complete 6 short answer and 2 fill in the blank questions.

Students measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

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

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

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.

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

Using an illustrated example, the difference between an endothermic and an exothermic reaction is described. The concept of enthalpy, or heat energy change, is explained, and the energy diagrams of reactions are presented.

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

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.

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

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, young scholars 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...

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

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

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 1 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."

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.
