Students identify the primary indicators of chemical change and learn about the law of conservation of matter. This unit also covers balanced chemical equations and showing reactants and products of chemical reactions.
The law of conservation of mass and balancing equations are the focus of this segment with students performing a lab to explore these topics.
This segment explores different types of reactions by performing a lab and talking with two special guests - Dr. Eileen Kennedy, who explains how scientists use chemical reactions to synthesize new medications, and Dr. Mike Petelle, who discusses acid rain.
This segment examines reactivity and predicting the products of chemical reactions by performing labs looking at metal reactivity and solubility with double displacement reactions.
During this segment, the students perform a lab to test and identify four unknown samples.
The students discuss their flow charts and lab results, explaining how they identified their unknown substances.
