Day 10--Unit 2



Well, tomorrow is parent's night. I am hoping for a big turnout, but I'll be happy even to speak to a room of four. It is always an energizing night for me, to make a connection with my student's parents.

Today in class was a day for adhesion and cohesion again. I filmed a small clip in the L section, but it is on my computer at school waiting to be processed. I'll post it soon. The video is of me putting a diaper in a large beaker and watching it absorb all of the water (well, actually about half of it) with the sodium polyacrylate that is inside it.

Here is the video of the diaper from the L section:



I also showed surface tension (a physical property) and stretch heated glass (another physical property). Tomorrow will be an inertia day, a more interesting day I think for students as I have an activity to get them involved.

Sweet justice.
