Classroom Resources: Solutions

1 – 4 of 4 Classroom Resources

• 

  Solubility, Solute & Solvent, Precipitate, 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!

• 

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

  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

  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.
