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

Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

Students examine different types of chemical reactions. They explore how alcohol molecules affect the reaction rates. They answer discussion questions to end the lesson.

Students research five types of chemical reactions in order to design a learning center. Students use technology to research and present their material.

Learners 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 describe and define chemical reactions. They design a laboratory experiment, collect data and analyze data.

Learners conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and splint tests.

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.

Students identify the factors that influence reaction rates. In this chemistry lesson plan, students design an experiment to test one factor they identified. They perform the experiment and share the results to the entire class.

Eighth graders observe evidence of chemical reactions.  In this chemical reactions lesson students study chemical processes and complete a lab activity. 

Young scholars explore the concept of chemical formulas.  In this chemical formula lesson, students watch a video about balancing chemical equations.  Young scholars conduct an experiment using silver nitrate and sodium...
