Today in class we took our first test.  The first part was filling in a blank Unit Circle and the second part was a two page (front to back) packet covering Bernouli's principle.  We were provided with a class set of calculators.  Mrs. Coats-Haan said it ws very important for us to clear the memory of our calculators.  This was done by pressing the 2nd button, then the Mem button and then the 3 button.  We then repeated this step, but pressed the 4 button rather than the 3 button.  After the test, we silently finished the Pondering Speed worksheet and were assigned to read pages 23 and 24 of the lab manual. 

Question of the day:  Give an example of an operational definition of a liquid.

Answer:  First, we must find out what liquid we are measuring.  For the sake of keeping it simple, we will say we are measuring water.  Next, we must pour the unknown volume of liquid into a graduated cylinder.  After doing this, we must get down to eye level with the liquid.  When we see that the top of the miniscus, the curved shape top of the water in the graduated cylinder, is at a certain number, we should write down the measurement to the nearest tenth in liters.
