This laboratory activity uses candy pieces of varying mass to represent isotopes of an element, candyum. The students calculate the average isotopic mass of candyum based on the average mass of a particular isotope and its percent abundance within the sample of candyum. Balances, calculators will be needed.
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.
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.
