Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...

Students investigate temperature using the TI. In this chemistry lesson, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Before completing this learning exercise, chemists are supposed read a portion of their textbook. Assign the chapter on bond energies, endothermic, and exothermic reactions. Then have your class answer the questions and fill in the data...

Students observe exothermic reactions in the lab using plaster. In this chemistry lesson, students collect data from their experimental set up every five minutes. They explain the different stages in the hardening of plaster.

This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

In this chemistry of ice cream activity, students investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students calculate...

Students investigate energy involved for bonds to form and break. In this thermodynamics lesson plan, students experiment with chemical reactions to observe endothermic and exothermic reactions, they explore entropy and the effects of...

All chemical reactions require energy. To explore thermodynamics, classes read and discuss its laws, exothermic and endothermic reactions, enthalpy in many forms, calculate enthalpy problems, and use Hess' Law to calculate enthalpy of a...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Can your scholars solve the mystery of why salts dissolve? A virtual workbench allows them to experiment with temperature and solubility with no solution prep and no post-lab clean up! Users determine the solubility of a variety of...
