This awesomely animated PowerPoint details the relationship between temperature and pressure for samples of gas at fixed volumes. Animations clearly demonstrate the increased linear speed of gas particles as they are heated. Relating this idea to the equation KE=1/2(mv(squared)), students determine that heating particles must mean that they are going faster.
Students organize their thoughts graphically and think about Charles's Law and Guy-Lussac's law as they watch a balloon expand over heat. They identify the difference between this easily observable demonstration and the laws discussed in this lesson, that the balloon does not have a fixed volume. Note: Plunge the system into cool water to watch the balloon invert. Challenge your students to explain the inversion!
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.
