Visual Models of Solutions and Concentrations
High schoolers model solutions with beakers of colored glass or plastic spheres. In this solutions lesson plan, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions. They...
Curated OER
Mixtures
Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.
