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.

Science 10: Today we read section 17.4 and did review 17.4 in sentences.  Later we will do 17.3.   We also did a quiz on Genetics Problems and on Human Reproductive Anatomy.

Chemistry 11:  I collected unit 3 # 33-44.  After doing a short WS called Atoms and Molecules, we read pg 65-73 and did #  1-7 (at least half the practice problems, but get enough practice to be good at these skills).  We finished with a quiz on Significant Figures.

Chemistry 12:  For review we did a quiz from last year.  We took notes on Mechanisms, then read section 1.9 and did # 46-52, followed by 41-45.  Lab 18C will be due Friday, and can be worked on only in room 313 (come whenever... lunch, other blocks, etc.).  No conclusion yet.


Friday, February 9

Science 10:  Today we marked the Genetics Review WS, and did a practice quiz on anatomy and genetics problems.  We did Lab 36 on Pedigree Charts, which is due Tuesday.

Chemistry 12:  Today we went to the Scholarship presentation.  We spent 30 minutes working on Lab 18C at the end.

Chemistry 11:  We did self marked lab 3A.  We took notes on Atoms, Molecules, and Ions.  After reading section 3.3, did # 33 - 44.

Science 10:  Read Section 16.4 and do # 1-7.  Label the male and female human reproductive anatomy sheet.  Do the WS titled Genetics Problems.  Today marked section 17.2

Chemistry 12:  Today we did Lab 18C, which is not due Friday.  We will go to the scholarship seminar on Friday.

Science 10, P78:  Read Section 16.4 and do # 1-7.  Label the male and female human reproductive anatomy sheet.  Do the WS titled Genetics Problems.  Today marked section 17.2 and I checked it.

Chemistry 11:  We started with a history lesson about the Berlin Wall from a performer named Devon Wall - wow!  In the second half we did Lab 3A (all procedure, Questions and Calculations 1,4, and Follow-up Questions # 2,3.

Chemistry 12:  Today we did a review WS on section 1.7 and 1.8.  Lab 18C needs to be prepared for Thursday, and you need to have your coil-bound notebook for Thursday, and it will stay in my room.  U1 # 37-39 is not due Thursday.

Chemistry 11:  Complete all the density calculations for Wednesday.  Ensure you have a ruler, 20 sheets of graph paper, and a calculator for this class.

Science 10:  Today we wrote a safety quiz, drew mieosis, and started a crossword puzzle that is not due next class.

Chemistry 11:  Today we took notes on Significant Figures.  We read pg 34-40 and did Unit II # 55-58.  We also reviewed the matter samples that we looked at on Friday.

Chemistry 12:  Today we Read sections 1.6 to 1.8 and did problems # 22-36.  We took some notes, finishing the table in Friday's notes as well as learning about Kinetic Energy Distributions.

Science 10:  We self scored the questions from section 16.3 (#1, 3-5, 7,8).  We also took notes on Mendelian Genetics, read 17.2, and did all of Review 17.2 in sentences.  Period 56 has a safety quiz on Tuesday.  Period 78 has a safety quiz on Wednesday.







Friday, February 2

Chemistry 11:  We reviewed measurement and did # 42, 46,48, 49.  We also took notes on the Categories of matter , filled in the last column of our Matter table with 3 items:  Heterogeneous/Homogeneous, Pure/Mixture, Element/Compound/Solution/Suspension/Mechanical Mixture.

Chemistry 12:  We read 1.4 and 1.5 and did all the problems up to # 22 in Unit I.   We finished with a practice quiz.

Science 10:  I collected the Mitosis Cut and Paste, Safety Map, and Review 15.4 # 1-5 from the handout.  We started with a quiz on cell anatomy.   After,  we took notes on Sexual Reproduction and read 16.3 from a hand-out.  We did # 1-5 in sentences.

Chemistry 11:  We started off with a short review of the Kinetic Molecular Theory.  After writing notes on "Chemistry" we observed about a dozen kinds of matter and recorded their physical properties.  After break, we read section 3.1 and 3.2 as far as Exercise #16.  We did U3 # 1-3, 5, 13-16 in point form, and as well pg 8 # 1-8.  We finished with a lesson on measurement, and how we are allowed to report all certain digits plus one uncertain digit.  Pg 34 #50 is also due for Friday.  Please always check your work against the answer key at the back of the Hebdon text.

Science 10, Period 78: Today we discussed Science Safety guidelines and created a map of our classroom showing safety equipment.  We took notes on DNA, then read 15.4 from a hand-out, and did Questions 1-5 in sentences.  In the second half we reviewed cell division and created a cut and paste showing the cell cycle.  We finished off by watching a video about "What happens when your DNA is damaged?" and doing a practice safety quiz.  All this work is due Friday.  On Friday, I would like to check your supplies and would also like to give you a quiz on Cell Anatomy.
