This lesson explains the difference between endothermic and exothermic chemical reactions. It is 2 of 4 in the series titled "Endothermic/Exothermic Reactions."

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

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.

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.

[Free Registration/Login Required] Explore endothermic and exothermic processes by making a cold pack or hot pack.

In this activity, students examine the size, mass, and growth rates for three species of fish. They interpolate and extrapolate from best-fit models. Students compare the growth rates of endothermic and exothermic animals.

The teacher will conduct the whoosh bottle demonstration to engage learners. The class will then begin discussion of endothermic and exothermic physical and chemical changes. The students will then conduct the Science in Motion lab...
