Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

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,...

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...

Young scholars define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.

Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.

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

For this thermodynamics worksheet, students calculate the change in enthalpy for several given chemical equations provided. Students specify if the reaction was endothermic or exothermic in nature.

Students investigate activation energy through endothermic and exothermic reactions. In this activation energy lesson plan, students conduct 2 experiments, one is an endothermic reaction and the other is an exothermic reaction. Students...

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...

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

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...

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...

Students 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 students to...

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 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...

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.

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

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...

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 reactions worksheet, students state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.

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