1 – 4 of 4 Classroom Resources

• Solubility, Solute & Solvent, Precipitate, Saturated/Unsaturated/Supersaturated | High School, Elementary School, Middle School

### Access is an AACT member benefit. 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!

• Molarity, Concentration, Saturated/Unsaturated/Supersaturated, Mole Concept, Dimensional Analysis, Stoichiometry, Balancing Equations | High School

### Access is an AACT member benefit. Lab: Kool-Aid

In this lab, students calculate grams of Kool-Aid powder required to make 3 different solutions of Kool-Aid (using the molar mass of sugar) with the following concentrations: 0.2 M, 0.5 M, and 1.0 M. Determine the concentration of properly prepared Kool-Aid through a taste test.

• Solubility, Saturated/Unsaturated/Supersaturated, Mixtures, Reaction Rate | High School

### Access is an AACT member benefit. Lab: Rate of Solution

In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.

• Exothermic & Endothermic, Physical Change, Heat, Temperature, Observations, Intermolecular Forces, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School

### Lesson Plan: Particle Modeling of Hand Warmers

In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.
