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...

You're getting warmer. Groups conduct an experiment to determine which of four chemicals are in hot/cold packs. They learn about exothermic and endothermic reactions and use this knowledge to design a hot/cold pack that is small enough...

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...

Young scholars measure the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter or Styrofoam cup and thermometer to measure the change in temperature of the water in their calorimeter. This allows young...

In this energy and matter worksheet, high schoolers define 28 terms related to moles, matter, energy, the Law of Conservation of Energy, mass, properties of matter and states of matter.

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...

For advanced chemists, this worksheet examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.

In this chemical reaction worksheet, students determine if reactions are exothermic or endothermic. Students define enthalpy and calculate how much heat is released or absorbed during reactions. This worksheet has 1 matching, 1 fill in...

In this chemistry learning exercise, students calculate specific changes that take place with different chemical reactions. Students indicate whether the reactions are endothermic or exothermic and spontaneous or nonspontaneous.

In this reactions worksheet, students use graphs showing reaction progress to determine if the reaction is exothermic or endothermic, the activation energy, and the enthalpy of change. This worksheet has 1 graph, 7 short answer, and 16...

For this physical vs. chemical change worksheet, students answer 10 questions about identifying chemical and physical changes. They identify exothermic and endothermic reactions and the parts of a chemical equation. Students answer 1...

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 chemical reaction learning exercise, students determine if given reactions are endothermic or exothermic reactions. Students determine the energy released or consumed when chemical reactions occur. This learning exercise has 5...

In this kinetics and equilibrium worksheet, students use the diagram to answer the questions as it relates to endothermic or exothermic reactions. Students indicate the result in the reaction rate as speeding up or slowing down.

Learners 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.

Students investigate which metal is best to use as storage material in hydrogen cars. In this chemistry lesson, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned in the...

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 chemical equations worksheet, students complete a paragraph about chemical equations by filling in 17 terms from a word list.

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

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

For this chemical reactions worksheet, students follow a flow chart to determine what type of reaction is occurring. Students then classify reactions and balance the equations. This worksheet has 2 short answer and 10 fill in the blank.

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

Chemistry can help athletes and others protect and treat injuries. Use the interactive activity to explore the chemical reactions in instant hot and coldpacks. Learners manipulate the type of salt in the pack and watch the reaction take...
