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.

[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.

[Free Registration/Login may be required to access all resource tools.] Students learn about the role of activation energy in a chemical reaction, and the difference between endothermic and exothermic reactions.

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....
