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...

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

For this chemical bonds learning exercise, students determine how much energy is needed to break bonds. Students classify reactions as exothermic or endothermic and identify a reaction as reversible. This learning exercise has four...

This worksheet focuses on writing equilibrium constants. High schoolers work to determine the direction of reactions, concentrations of different substances, and equilibrium constants.

Students study oxidation and define vocabulary pertinent to it.  In this oxidation lesson plan students make predictions and create experiments

Learners measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

Middle schoolers 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.

In this chemical reaction worksheet, students determine if given reactions are endothermic or exothermic reactions. Students determine the energy released or consumed when chemical reactions occur. This worksheet has 5 problems to solve.

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.

For this equilibrium worksheet, students solve 8 problems to find the equilibrium constants and reaction rates of given equations.

Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...

For this chemical equations worksheet, high schoolers complete a paragraph about chemical equations by filling in 17 terms from a word list.

In this chemical equations instructional activity, students complete a paragraph by filling in the 17 terms associated with chemical equations.

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

An organized table charting the different types of chemical bonds arrays this resource. The octet rule, ionization energy, and the naming of compounds are also reviewed. Young chemists answer review questions in multiple choice fashion....

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

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...

Learners investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry instructional activity, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies...

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...

For this science worksheet, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

In this reactions worksheet, high schoolers describe combustion as either exothermal or endothermal. Students balance reactions and label the types of reactions. This worksheet has 1 multiple choice, 2 short answer, and 10 problem...

In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

In this equilibrium worksheet, high schoolers read about the factors that effect equilibrium in solutions such as the pressure of the solution, the temperature and the concentration of the solution. They answer three multi-part questions...
