12/12 Biology update and homework due 12/19

Hi folks,

This week in biology we took a good look at the outer cell layer and explored how materials get into and out of the cell.

Just for fun, this is an amazing little game that really gets a pretty good handle on what's going on with the cell.  Give it a shot if you have some time.

Homework Due 12/19 is to:

Read Chapter 5 pages 96 - 106
answer questions 1-8 page 102

11/14 Biology update and homework due 11/21

Hi folks,

Today we covered enzymes and proteins.  Homework for this week is to read the following website.  Don't  worry about clicking on the follow up links unless you're interested on your own.  http://www.chemguide.co.uk/organicprops/aminoacids/proteinstruct.html

Also, we saw a small video in class showing the different structural levels of protein.  Here's that video. http://www.youtube.com/watch?v=lijQ3a8yUYQ

Answer the following questions based on the lecture and the website information.

1.  What is the basic pattern of atoms that you see when amino acids combine?  For example c-c-o-n-c-n etc.


2.  What is the method by which amino acids combine?


3.  What types of bonds hold amino acid residues in their shapes?


4.  What is meant by denaturation and what can cause that?


5.  Why is it important that proteins hold specific shapes?


6.  What is a fibrous protein?


7.  What is a globular protein?


8.  What two functional groups are on an amino acid?


9. How many amino acids are there?


10. Describe the differences between the 4 different structural levels of proteins.


11.  What are the 5 different subcategories of proteins?  Give an example of each one and what it does.


12.  What are 4 things that enzymes do?


13. What is meant by "Lock and Key" when it comes to enzymes?


14. What is meant by the active site when it comes to enzymes?


15.  What is meant by the substrate?

11/7 Biology update and homework due 11/14

Hi folks,

Today we basically spent the entire class on a lab where we used different indicators and attempted to find which foods contain which biological molecules. There will be no recording for this week since we spent the majority of class on the lab.

Homework for this week is to complete the enclosed .pdf.
Remember to study those flash cards!!!!

Oct 31 Biology update and homework due 11/8

Hi folks,

Last class, we spent a bunch more time on those unbelievably exciting biological molecules!  I know folks can't wait to do more with those, so your homework this week is to create flash cards of all 4 of the biological molecules and all the functional groups we went over in class.  Use index cards and put the name of a group or molecule on one side and then draw the molecule on the other.  I'd highly recommend using them to test yourself as well, since the next several quizzes will certainly have a bunch of those on there.  You will have to draw the molecules or groups for the quiz.  You'll also need to know what functional groups are associated with what biological molecule.

Also, using your new knowledge, see if you can find 3 things that would be a good representative of something containing lipids, something containing nucleic acids, something containing proteins and something containing carbohydrates.  3 things for each molecule so 12 things all together.  These need to be things you can see/touch around you.  (Hint…look in your fridge… :)  )

10/24 Biology update and homework due 10/31

Hi folks,

Today we spent time going over the functional groups and 2 of the 4 major biological molecules.  What they are and what they do.  Next week we'll take a careful look at what they look like.

Homework for this week is to:
Read pp. 51 - 61
Do questions 1-7 on pg. 54
Do questions 1-7 on pg. 60

Recording for 10/17 Biology Class: Solubility and Acids and Bases

https://www.youtube.com/watch?v=nJBOVYCYfwM&list=UU-GWClOchspYJsrfzvZfq-A

10/17 Biology update and homework due 10/24

Hi folks,

Today in biology we did a bit more work with solubility as well as introducing the concept of acids and bases.  We also did a brief lab in order to get the hang of using litmus paper and pH.

For homework this week:

Read 42 - 44
Answer questions on:
pg 37 #'s 1-5
pg 44 #'s 1-6

Using the interwebs, or your knowledge from the lab, name 3 household items (things actually in your house right now) that are acids and 3 that are bases.

Revision in homework due 10/17

Hi folks,

I made a mistake and assigned several questions this week that I assigned last week as well.

So for homework this week take about 10 minutes to watch this video about water from Crash Course Chemistry.

Answer the following questions.

1. What kind of bonds does a water molecule have?

2. Which side of the water molecule is positive and which is negative?

3. What does Hank say is the most important thing about water??  (He says you should put this in capital letters.)

4. What is the definition of cohesion?

5. What is the definition of adhesion?

6. What is capillary action?

7. What is the definition of solvent?

8. What is the definition of solute?

9. What is meant by the fact that water has a high heat capacity and why is that important?

10/10 Bio update and homework due 10/17

Hi folks,

Today we did a bit more work with the wonderful substance that is water and we also got into some more general concepts such as cohesive, adhesive, and solutions. We did a quick lab taking a look at the solubility of salt and sugar in water.

For homework next week:

Do Review Questions on Pg. 46 #'s 9-17
And do Critical Thinking questions on page 46 #'s 22 and 23

Hi Jim,
Thanks for the fun class on Friday!
I just wanted to let you know that I tried the blog link but it didn't seem to work. Brought me to a newly composed email with the email address:


Am I doing something wrong? Or is that not the right link?

Thanks again!
All the best,

Hi everyone,

It's great to get started!  Looks like we should have a good group of folks and an excellent class.

Today we took some time to give a brief overview about what science is, what does it mean, and how does it work.

Here is the link to the blog.  All emails, updates, class recordings, homework assignments, etc. go here.  It's a nice easy way to keep up with what's going on with class or to catch up if you've missed something.

Here's the link to the recording for this week.
