1 – 4 of 4 Classroom Resources

Solubility, Covalent Bonding, Precipitate, Ionic Bonding, Molecular Structure, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School

Lab: Benzoic Acid Blizzard in a Bottle

In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.
Solubility, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | 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!
Naming Compounds, Molecular Formula, Precipitate, Ionic Bonding, Ions | Middle School

Activity: Bond with a Classmate

In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.
Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules, Reactions & Stoichiometry | High School, Middle School

Lab: Predicting Precipitates

In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.
