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,...

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...

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

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...

Students explore the mesosphere and lower thermosphere globally and achieve a major improvement in our understanding of the fundamental processes governing the energetics, chemistry, dynamics, and transport of the atmospheric region....

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...

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...

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.

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

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.

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...

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. 

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...

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

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

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 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...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

Young scholars engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The activity does not contain a true understandable objective. The...

Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.
