This lesson teaches students the definition of solution as a homogenous mixture, a much more flexible definition than most people presume. Brass, therefore, is a solution!
It also teaches students that a solution can usually be identified by passing a beam of light through it. A homogenous solution will not deflect the light, and, therefore, it will pass through the solution undisturbed.
The lesson also addresses solute vs. solvent, another tough topic for some students.
Most of my chemistry lessons are 8 slide PowerPoints. I print the PowerPoints each day (4 slides per page... front and back = 1 sheet of paper per student). The students then fill out the answers to my guided and scaffolded questions as I fill them out on the SmartBoard. My teaching style is highly interactive, and my lessons support that style.
All lessons include a Do Now, Mini Lesson, Pair Up, and Summary to keep students moving and engaged.
To remove the "Wickline" watermark, select the Watermark from the Insert menu, then select No Watermark. You cannot remove the watermark's from .pdf files and SmartBoard files, so you'll have to make new ones from your fresh watermark-less Microsoft file.
