Science 10:  Today we learned about how the information in DNA is used to build a protein, which will likely go on to catalyze a chemical reaction.  We took some notes,  watched "From DNA to Protein", and read pg 141 - 146 in the old Nelson Biology 11 text.   We did pg 153 # 1-25 (all MC, answers only).  In the second half, we measured the lengths of about 250 beans and graphed the #beans vs the length, which revealed natural distribution (or bell curve).  This notion of variation among a population was the lead into "Natural Selection", which is the best explanation for all the diversity of life on this planet. Whew!  We learned a lot today!

Chemistry 11:  Today we started with   safety assignment, and spent the rest of the class doing lab 2E, the Law of Definite Proportions. All the Calculations and Follow-up Questions are due on Friday.  The trick to this lab is to make sure everyone is applying those rules of measurement and reporting of significant figures.
