In this general science activity, learners 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 explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

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

In this chemical equilibrium worksheet, students read about how additions to a system can shift the equilibrium. Students then apply the Le Chatelier's Principle to solve 5 problems.

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.

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.

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

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

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

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

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.

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...

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

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.
