SUMMARY: Children take a trip through several fields of chemistry and discover the factors that can change the rate of a reaction. The class begins with a role-playing activity in which volunteers act out two different rates of reaction. This is followed by a hands-on demonstration on oxidation where the role of salt—as a catalyst—is observed. The instructor demonstrates quick-acting reactions such as precipitation and acid-base reactions, followed by a balloon-expanding experiment to test limiting reagents (factors). Children will explore crystallization and receive a Take-Home Action Flask kit to perform more experiments. The class wraps up with a color-changing electrolysis demonstration that covers these cool chemical concepts.
EDUCATIONAL VALUE: This class introduces the factors which determine chemical rates of reaction. Several fields of chemistry will be presented, and students will explore the many ways in which different chemical processes can be sped up through the use of catalysts. The concepts demonstrated in this class will encourage students to link experimental factors with a chemical rate of reaction. Students will participate in hands-on activities and view demonstrations on various chemical rates of reaction.
NOTE: Mad Science Programs are fun explorations into science and technology, and they encourage informal learning through hands-on experience. All Mad Science workshops include a lot of fascinating equipment, supplies, and take-home materials which the children build themselves. The Mad Science mission is to spark the imagination and curiosity of children everywhere by providing them with fun, entertaining, and educational activities which instill a clear understanding of what science really is, and how it affects the world around them.
