Biology 12

Today we took notes on smooth and rough ER, Golgi Body, Vacuoles, Vessicles, and the secretory pathway to leave the cell.

We still have our lab on plants and animal cells to finish off, but we will leave that until tomorrow's double block.

We did a plant and animal cell coloring and matching sheet which is due tomorrow.  The Unit review is due on Friday as well as all the booklet questions. 

Biology 12

Today we did a microscope lab on Cells.   We looked at some plant and animal cells and tried to distinguish some structures:  Cell membrane, cell wall, chloroplasts, nucleus, cytoplasm.   We also made microscope drawings and calculated the magnification of the drawing based on the diameter of the field of view.  

Chemistry 11

Today we wrote a quick question quiz on measurement and significant figure calculations.

I did some demos:  1) What happens if you get acid in your eye?   Gross right!  Wear goggles kids....
2) Some chemical and physical properties of ethanol.  

Next I gave out some notes on Scientific Method and Physical and Chemical Change and Classification of Matter.  We talked about the ways that matter can be classified.

We finished with a "Quick Non-Formal Lab"  on the density of 3 liquids.   Students collected data which will be used by the class on Monday.

Chemistry 11

Today I collected Hebden Exercises #13-15 on pg. 44.

We took notes on the 3 states of matter and how the particles act in each state.   We had some time to work on Lab 1A (due tomorrow) and Unit 1 review (ready to check next Tuesday Feb. 14.)

Second block we used our vast knowledge of significant figures and measurement uncertainty to determine the thickness of  two types of aluminum foil.  How crazy is that!

Quick Question Quiz tomorrow

Biology 12

Today we got back our biomolecules quiz.  Good work!   If you would like to improve your score, make sure you turn in quiz corrections sheet and re-do the quiz Friday at lunch.

We looked at a short video on the Cell.  (Crash course in Biology series) and then took some notes on cells and their organelles.    Booklet Questions part B (Cells) up to and including Endoplasmic Reticulum is due on Friday Feb. 10.

Also due on Friday is the Buffers Lab.

Today we kept working on Lab 1A.  It is a loooong lab, so don't worry if you have only filtered your calcium hydroxide.

We took notes on matter and on the properties of matter including examples of descriptive and quantitative properties.

Homework:  read Hebden pg. 41-42 Do pg. 43 #1-4

Biology 12

Today we took notes on Lipids and Proteins (see pictures below).

Tuesday there will be a quiz on Biological Molecules up to/including proteins.    Your booklet questions up to this point are due then. 

For Monday:  Complete Worksheet:  Biologically Important Molecules. 

Chemistry 11

Today we reviewed questions about measurement and significant figures from the Hebden homework.  I collected #42, 44, 48 and 49 from Hebden.

We started Lab 1A and you all should have gotten to the point of weighing out 3 grams of calcium hydroxide.  Hebden homework:  pg. 37 #55, pg. 39 #56 abcde,   pg. 40  #57abcde

Biology 12

Today we discussed the fact that besides water there are four main types of chemical compounds in our bodies.  They are:  Carbohydrates, Proteins, Lipids (fats) and Nucleic Acids.   One thing they all have in common is that they are all polymers (chains of repeating units).  

We looked at how polymers are made:  By dehydration synthesis and how they are broken down into their small units:  By hydrolysis.

Next we looked in depth at carbohydrates and learned of some monomer and polymer names.

HOMEWORK:  Complete Section A part C) Biological Molecules of the Cell for tomorrow.

Second Block:  We did a lab on Antacid Buffers.   This will be due next Friday Feb. 10th.  

Chemistry 11

Today we took lots of notes on how to express measurements in Chemistry.   Notes on metric conversions with two steps, scientific notation and significant figures.

We got ready to do our first lab, but did not start it yet.   We will begin this Friday.  

Homework:  Finish setting up and reading lab 1A pg. 1-8 in the lab manual

Hebden:  pg. 28 #42, pg. 29 #44, pg. 32 #48, pg. 33 #49.
