This PowerPoint introduces the concept of Half-Life to chemistry students in a friendly, guided fashion. Surprisingly, however, it manages to cover a lot of ground from concept through solving various half-life word problems.
The word problems are present in order of challenge level, and are meant to be worked through as a class. Students will need calculators.
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.
