Solution Concentration

For the first lesson of Chapter 15, students were immersed in the vocabulary of solution concentration.  The Lesson 80 PowerPoint includes six important vocabulary words that students recorded in their lab notebooks. Students received the Lesson 80 Worksheet and worked together in groups to complete Part 1.

For Part 2 of the worksheet, students were shown gummy bears (Haribo) that had been placed overnight in either water, 0.1 M sugar, 1.0 M sugar, 2.0 M sugar, or corn syrup  The gummy bears were rinsed and the mass was measured.  The results are pictured below:



The video of the supersaturated salt solution shown in the PowerPoint is also available below:
