Chemistry 1 – The three separate gas laws can combine into one mathematical model that relates all of the variables that effect gas pressure.  I introduced the class to IFE tables to help organize and predict gas pressure situations.  I showed the class one example problem and how the theory and law work together.

Physics 1 – Full analysis of the Bowling Ball Grand Prix was done by today drawing diagrams for when we did the activity out on the grass.  I think the idea of needing balanced forces on an object to keep it moving constant velocity was easily visualized and agreed upon by the class.  Having the feeling of making this happen outside I think helped this process.  The discussion the one class had revolved around the fact that in order to get the ball moving you need a push greater than the friction force, if you stop pushing you slow down, so if you push enough to balance the friction the ball will continue to move, but not speed up or slow down.  PHYSICS WIN!

Chemistry 2 – I introduced our next unit of study which the class voted on to be organic chemistry.  (I gave them a vote between organic and nuclear).  Because organic chem uses such a different language then we’ve been speaking I started the unit with a set of notes that explained what organic chem is, why carbon is so special, how we name simple straight 1 – 10 carbon chains, and different ways to represent organic compounds.
