Table of Contents Chapter 6: Cool Chemistry Show |
|
Chapter ChallengeOne of the best ways to demonstrate that you understand the chemical concepts that you have studied is to teach those concepts to others. Your challenge in the Cool Chemistry Show chapter is to demonstrate chemistry concepts to grade school children. You not only demonstrate the concepts, but also have to be able to explain them and to answer questions on the concept you are presenting. |

Activity Summaries |
Chemistry Principles |
Activity 1: Chemical and Physical Changes Students learn what conditions are necessary in order to determine whether the process is a physical or chemical change. |
|
Activity 2: More Chemical Changes Students learn what characteristics are used to identify a chemical reaction taking place, how indicators are used to identify acids and bases, and tests used to identify gases.
|
|
Activity 3: Chemical Names and Formulas Students learn how to use the symbols from the periodic table and how to write the correct formulas of compounds. In addition to writing formulas, they will also learn how to name compounds. |
|
Activity 4: Chemical Equations Students practice writing chemical changes by using word equations and chemical equations. In addition to learning how to express an equation, they will also study single-replacement and double-replacement reactions. |
|
Activity 5: Chemical Energy Students learn how to use chemical thermodynamics to produce products that use endothermic and exothermic reactions. |
|
Activity 6: Reaction Rates Students study those factors that can alter the rate of a chemical reaction. The factors studied are temperature, concentration, the nature of the reactants, and catalysts. |
|
Activity 7: Acids, Bases, and Indicators—Colorful Chemistry Students study the special properties of acids and bases. Special properties that the student will need to understand: how they react with metals, how they feel, how they taste (however,remember that you do not taste chemicals in the laboratory), and how they can be tested for using indicators. |
|
Activity 8: Color Reactions that Involve the Transfer of Electrons Students investigate metal activity. They study oxidation and reduction and how we might be able to control them to our benefit. |
