Science 9:   We began with an assignment where we practiced skills with Scientific Notation and number prefixes [ kilo = 1000, Mega = 1 000 000, Giga = 1 000 000 000].  Click here to see the WS.  Click here to see the key.  Time was given to complete the Electronics Booklet, which can be accessed from January 11th's post.  Click here to see the Electronics booklet answer key.  In the second half we learned how to measure the voltage of cells and batteries, and we recorded data on a number of types of sources (D, AA, AAA, coin batteries, Automotive batteries, 6V batteries).  In the final portion of class we read section 10.1 in Science Probe 9 and did pg 305 # 1-10, 12, which is due on Friday.  

Chemistry 11:  We began with a short review of functional groups, then we learned how to write organic reactions that form esters from carboxylic acids and alcohols.  We completed a home made worksheet with 5 reactions, this is due Friday.  Time was given to complete the Organic Practice Test, which is due just before you write your Organic Chemistry Test on Monday.  The last portion of class was spent on writing Dissolving Reactions and stating the concentration of each ion in solutions.  This video clip shows an animation of dissolving ionic NaCl, showing the free ions produced.  Numbers 1 - 4 on the Concentration of Ions WS is due Friday too.  Click here to see the key for # 1-4
