Lesson Plan: Removing Copper Stains from Masonry
In this lab, students investigate the use of milk of magnesia poultice to remove copper stains on masonry in copper architecture. They use chalk as the model for masonry, copper(II) chloride solution as a model for soluble copper and a freshly prepared slurry of copper phosphate as a model for a hard stain of copper on masonry. Through a series of investigations students have the opportunity to connect chemistry topics with real-world applications, such as environmental hazards, engineering practices of copper architecture, corrosion control, and structural protection.

Electron Configuration, Precipitate, Balancing Equations, Electrons, Valence Electrons, Solubility Rules, Classification of Reactions | High School
Lesson Plan: Transition Metals Color the World
In this lesson students will complete a series of double replacement reactions to form precipitates. The precipitates will be used as a pigment to create paint.
-
Solubility Rules, Classification of Reactions, Precipitate, Net Ionic Equation | High School
Lesson Plan: Do it Yourself Color!
In this lesson students will use solubility rules to predict whether the product of a double displacement or metathesis reaction will produce a precipitate. Students will then investigate a series of reactions to verify solubility rules. Finally students will determine the identity of unknown solutions based on experimental evidence.

Balancing Equations, Precipitate, Solubility Rules | High School
Animation: Net Ionic Equations Animation
In this animation, students will witness a precipitate reaction on the particulate level to understand why a net ionic equation represents what happens in these reaction types. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**

Solubility, Solute & Solvent, Precipitate | High School, Elementary School, Middle School
Lab: Winter Crystals
In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!
