Product Details

Demonstrate to your students what the alchemists only dreamed about. Turn an ordinary copper penny into silver and then into gold. Students will watch as you place pennies into a chemical solution that turns the pennies silver. Then, over heat, the silver penny will change into “gold.” Teacher Demonstration Notes included.

Concepts: Oxidation–reduction, alloys.
Time Required: 15 minutes
Note: Shiny pennies are needed, but not provided.

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-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
