In this nuclear reaction worksheet, students determine the missing particle from the reaction and then name that particle. This worksheet has 18 problems to solve.

In this carbon dating worksheet, 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.

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.

This lesson explains the difference between endothermic and exothermic chemical reactions. It is 3 of 4 in the series titled "Endothermic/Exothermic Reactions."

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.

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, 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,...

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.

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.

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.

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...

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