This week, we started off with test prep for the first test on Wednesday. The first test was as hard as expected, and I suppose I didn't study enough for it. Those HotPots were a great way to study but they weren't enough to be able to do well on the test, as I now know. At least I know now how much I need to study in the future.
We were assigned new table groups and got new roles for pogils, as well. We tried them out later in the week. My role of recorder is actually a lot more difficult than I would have imagined, having to write and present the material. But, it forces me to learn so I like it.
After the test, we focused on Lewis models and Lewis structures in a pogil. These diagrams focus on how to represent the valence electrons of atoms and in turn how they bond with each other. They're also a good way to be able to see how atoms bond, and why some atoms are more easily bonded with than others. For example, the noble gases don't bond very often because of their full outer electron shell, and that is clearly shown in the diagrams. Here is a good link to how to make Lewis representations of atoms. It shows how to place the dots and how to label where bonding is ocurring. Lewis structures also are an application for electronegativity. The most electronegative atom will the in the center of the Lewis representation.
Lewis structures can be simple, but most are complex. It's mostly a problem of making sure there are the correct amount of valence electrons. I think I have the basic ideas down, but I could use some more practice, of course. I'm sure we'll be doing just that next week.
