Product Details

Studying reaction rates helps chemists make a variety of products, everything from antibiotics to fertilizers, safely and economically. The purpose of this microscale activity is to teach students how reaction rates are measured and what reaction conditions will affect the rate. Students investigate the “blue bottle” reaction of methylene blue, varying the temperature and the concentration of reactant. With reagents sealed in small plastic pipets, the reactions are simple to set up and even quicker to run. You will be surprised at how easy kinetics can be—perfect for a hands-on introduction to a difficult topic! Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to questions and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs.

Performance Expectations

HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-8: Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
