Chemistry 11

Today we finally finished Lab 1A.   Lab is due with all questions and follow-up questions and a conclusion on Friday.

Also on Friday a quiz on Measurement and Sig. Fig. Calculations.

Hebden homework:  Read page 44.  Do Exercises #13-15.

Biology 12

Today we wrote our first quiz on Biomolecules.  

Took notes on Nucleic Acids and learned what is required for the Buffers Lab (due Friday).

Today we finished off our notes on proteins by looking at the 4 structures of proteins.   We answered some protein questions and did a practice quiz to practice for our quiz on biomolecules tomorrow.

Chemistry 11

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.
