Science 9:  Today we used multimeters to measure the voltages of batteries and cells, to see if they are "dead" or not,  Even a small reduction in Voltage will mean that the amount of current available from a source will not be enough to run your device.  We spent more time on our Electronics Booklet too.  Nothing is due for Thursday.

Chemistry 12:  Prepare Lab 21C for Wednesday am.  We spent the class reviewing Unit 1, Rates of Reaction.  Please ensure that you are spending time preparing for your final exams.
