Lab, new optional assign, Exam next Wed.

I haven't finished scanning the review pages; hopefully those will appear online here tomorrow before school is out.

Wednesday we had a lab involving phase changes of water - and a couple of side labs too - melting ice with pressure rather than thermal energy (since water is a rare substance where its solid form is less dense than the liquid form), and melting ice with salt - again, no thermal energy added by the salt, but a change of the ice's melting point and the temperature at the outside of the ice cube, being lowered, increases the rate of thermal energy absorption for the ice cube AND keeps the water liquid at temperatures well below its usual melting/freezing point.
Labs are due tomorrow (Friday) and have been homework/classwork for this week.

Today classes got to see a barometer, watch the forecast (we'll see how the barometer reacts tomorrow as the Low pressure cell is supposed to move in before the weekend's High), read through a packet of review material (will be online ASAP for you to review), and we discussed observations from yesterday's lab along with any questions about the lab, graph, or post-lab questions.

Tomorrow we'll hopefully have a couple of new demonstrations (I haven't done them before) and I will try to address some of the questions on the lab that you were asked to make educated guesses about.  We'll also have some notes on phase changes and try to use data from your lab to support the ideas discussed.  Homework will be review problems; they will be posted online tomorrow.

I have been asked by several folks to put up a new optional assignment, and the one I was hoping to use for meteorology isn't going to work.  Here's an alternate - there are two different pages you'll need.

I'll try to give you some good ideas for this in class early next week, and put a list up online of some good ideas to help you out.  Due date for this is Friday, April 13th.
