This lesson explores the proper IUPAC writing of chemical formulas.
Firstly, the need to equalize charges using the charge crossing system is emphasized to produce the correct ratios of elements for a neutral compound. Secondly, writing formulas involving transition metals and the use of Roman numerals (the stock system) is introduced. Lastly, compounds containing polyatomic ions, and, therefore, needing parenthetical separations from the other ions, is addressed and practiced.
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.
