So here we are on Friday. Schedule change, lab is back in, today is still second part of the Gas Stoichiometry unit, but we also demonstrate the procedure for the lab.
Biggest thing: a window blew open in our classroom during one of the snow days, breaking one of the 2000 mL Erlenmeyer flasks and making the room SUPER cold. I spent prep time working on lab and class, working the homework problems and trying to keep feeling in my feet.
AP – They are doing heat and phase changes. Why does water cool you from evaporation?
Chem 1 – Today was a whole lot of sample problems! I knew that was kind of the point, showing some of the complications that can arise when there’s a reaction involving the gas phase, but the problems were still long ones and I had to go hard through the whole classes. The physical effort of writing that much on the chalkboard, even with as much as possible prepped beforehand, was a little surprising. At least I was warm at the end of all of it.
Chem 2 – We got out of the classroom to take an online quiz today. Our approximation to the Community College Testing Facility is a computer lab with us walking around, no big deal. They finished the quiz fairly quickly and went to work on online homework, which we helped them out with.
