Here is a five-day module in which high school chemists determine what other materials can serve as catalysts for producing ethanol. Another objective of the lessons is to introduce reaction rate and activation energy. Learners also use a computer to analyze and present their data.
Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction. Students use retest methods to determine how using various amounts of initial reactants changes the reaction rate.
Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These and other included activities are meant to contribute to understanding what affects the rate of reaction.
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the conventional step-by-step manner. A worksheet is provided with questions to help learners process their observations. Although this was written for a high school chemistry course, it seems more appropriate for middle schoolers.
In this chemical reactions worksheet, students determine the reaction rate for various reactions, write balanced equations, create graphs showing the reaction over time, and calculate the activation energy and potential energy. This worksheet has 1 graph, 5 fill in the blank, 2 short answer, and 20 problems to solve.
