Product Details

General, Organic and Biological Chemistry Illustrate the chemistry of oxidation–reduction reactions by creating a beautiful silver ornament! Simply combine four solutions in a glass ornament ball, swirl and viola—a thin, lustrous, silver coating plates onto the inside of the ornament. Besides creating a beautiful ornament, students also calculate the thickness of the silver mirror and estimate the number of atoms in the silver layer. You will find students “reflecting” on oxidation-reduction reactions in a whole new way! Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
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.
