Science 9:  We began by measuring the voltage of some cells and batteries, and we calculated the percentage decrease in voltage.  We also stated whether they were cells or batteries.  Time was given to complete the Electricity booklet, but this is not yet due.  We took notes on Measurement in Electricity, then we read pages 217 - 220 in our text.  We completed pg 227 # 1-9 in fine sentences.  Next class we will use multimeters to determine what happens to the total voltage when cells are connected in series.  

Science 8:  We began with lab 10-3 where we learned about how salinity affects density in water.  We spent just a little time learning about the bits that make up neutrons and protons, fundamental particles called quarks.  This video clip explains the Standard Model in brief.   In the second half was spent on Chemistry unit practice test, which is due on Friday.  Our Chemisty unit test will be on Monday.
