Science 90 - Nov 26

Today we had a chance to review our exams from the chemistry unit.  We then went over the homework from yesterday.  Students did some questions from the textbook as well as a worksheet related to static electricity.  I had students hand in the worksheet and it will be marked.  We then started to look at current electricity and the similarities it has with moving water.  The terms of voltage, current and resistance were introduced.  However we were not able to make it to the assignment for today's lesson.  We covered slides 17-23.  Tomorrow we will finish these notes.

Physical Science 20 - Nov 26

Today we finished looking at enthalpy by studying Hess's Law.  This is where we were able to find the change in enthalpy of a reaction by breaking the reaction down into the parts that make it up.  We looked at the example with cellular respiration.  We then did 2 more examples from Assignment H4.  Tomorrow we will do another example and then have the rest of the class to work on Assignment H4.

Science 90 - Nov 25

Today we went over the assignment from yesterday.  We then learned about electrical conductors and insulators as well as what an electric discharge is.  These notes were covered on slides 12-16 of the electricity powerpoint.  Students were assigned the homework on slide 16.  This includes a handout that I gave today in class.  Make sure to complete that as I will be taking it in for marks.

Tomorrow we will start to look at current electricity.

Physical Science 20 - Nov 25

Today we spent a lot of time going over Assignment H3 on combined heat problems.  This was in preparation for the take home assignment on calculating quantities of heat.  I handed this out in class today.  We began to learn about enthalpy today.  We learned how they measure the energy that is available in foods.  One can simply use that food to heat up water and determine the heat change in water or one can break done the food into its parts (fat, carbs, protein, etc) and know the energy in the parts, one can figure out the energy of the whole.  This will apply when we are finding the energy present in chemical reactions.

This was all covered in the powerpoint called Enthalpy.  We covered slides 1-11.  Students were given a notes handout that they used to follow along with the presentation.  This allowed students to just listen the presentation.  Tomorrow we will finish the notes on Enthalpy.

Physics 30 - Nov 25

Today we had a work period to prepare for the various things that are happening this week in class.  Students took the time to prepare for the unit 3 exam which is on Thursday.  They also worked on getting Lab 3.2 done, which they will be handing in on Friday this week.  As well, some students worked at correcting their lab 3.1 reports.

Tomorrow we will be having another work period.

Science 90 - Nov 24

Today we started our new unit on electricity.  We learned what causes electricity as well as how objects can become charged.  This was all covered in the new powerpoint in the Electricity folder in the Science 90 course notes link.  The powerpoint is labelled Characteristics of Electricity.  We covered slides 1-10 and students spent the remainder of class working on slide 11.  This will be checked tomorrow.

Tomorrow we will look at conductors and insulators as well as electric discharges.
