Making Sense of Percent Concentrations: Mix It Up

This unit from Illuminations includes activities that help students explore percent concentrations. Two lessons are included. "Mix It Up," which involves using two colors of beads to form two different percent mixes. The class will develop a formula to determine the final percent mix. The second lesson, "Don't Freeze the Engine," which uses an antifreeze chart to analyze how much antifreeze liquid to use to get the desired percent concentration. The material is intended for grades 9-12 and should require 3 class periods to complete.
