Here is a terrific learning game that has pupils acting like lizards! Before the game starts, there is a class discussion on the differences between endotherms and exotherms. The main focus of the game is how each team must keep...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge in...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

The fifth activity in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Some reactions absorb heat while others release it. Young scholars investigate both types of reactions in a 12-lesson unit. Each lesson presents a lab investigation that monitors temperature and considers the types of reactions taking...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

A 30-question multiple choice chemistry test challenges takers. Topics touched upon include thermochemistry, equilibrium, behavior of gases, and pH. Problem solving is required in order to answer most of the questions. Other questions...

In this equilibrium worksheet, students predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This worksheet has 15 multiple choice questions.

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...

Pupils experiment, observe, measure, and analyze what occurs during an exothermic reaction. They safely design an experiment, control variables, and properly dispose of materials.

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

In this chemical reactions worksheet, students learn about the 5 types of chemical reactions as well as endothermic and exothermic reactions. Students are given 5 equations to balance and they identify the type of reaction for each...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

A valuable resource provides a list of concepts that young chemists should grasp. The topics include energetics, kinetics, equilibria, redox reactions, and the halogen group. Employ this as a guide for your own curriculum planning, or a...

In this chemistry of ice cream worksheet, 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...

Students compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.

For this physical vs. chemical change worksheet, high schoolers answer 10 questions about identifying chemical and physical changes. They identify exothermic and endothermic reactions and the parts of a chemical equation. Students answer...

In this thermochemical equations worksheet, students read about and practice writing equations for thermochemical reactions. They also sketch enthalpy diagrams of the equations if applicable.

In this thermochemistry worksheet, learners answer twenty multiple choice questions about heat, enthalpy changes, thermal, mechanical and electrical energy and the laws of thermodynamics.

In this thermodynamics worksheet, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter instructional activity students divide into groups and complete a lab experiment. 

In this equilibrium and water chemistry worksheet, students solve twenty problems related to acids and bases, equilibrium and water.
