This lesson introduces students to the idea that the bond type of a substance plays a significant role in determining that substance's set of properties.
The lesson begins with animations to help students visualize that breaking and forming bonds have different energetic effects.
It goes on to describe crystalline structures as being ionic properties. Following from the crystalline structure, students can imagine that high melting point, brittleness, and non-conductivity (except when melted or dissolved) would result.
Lastly, covalently bonded substances are described as having low melting points and being flexible as properties of their bond structures.
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.
