This lesson introduces the topic of Lewis Dot Structures for atoms and ions. I created a neat graphic to show the ordering of the dots around the elemental symbol, an often neglected detail to Lewis Dot Structures that is very helpful when drawing Lewis structures for molecules.
Students then learn the rules for drawing Lewis dot structures for positive and negative ions.
The lesson culminates in a mixed up Lewis dot structure activity sheet.
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.
