LECTURE 3A: Chapter 4- part 1
Covalent Bonds
(NOT on Exam 1)


Test this week (Week 3)
I would recommend creating an index card, with anything you choose written on it, to use for the test.  Since it is an exam that you are taking online, and it won't be proctored, you can use your notes.  However, it is a 49 question test and you will only have 60 minutes to take it.  Therefore you will not have time to look for answers in your notes.  Therefore I would suggest creating an index card to use as a study tool. 

Be certain to take and then study the results of the online review quiz in Week 2. 

Remember if you don't take the test by Thursday of Week 3 you will have to go to the LCC testing lab to make up the test.  You will NOT be able to take it from home.  The testing lab does not have an open note policy, but you can use a 3x5 notecard.

Supplementary Videos in Moodle:

This week you will have an introduction to atoms, elements, covalent bonding, photosynthesis, and cellular respiration.  These topics can be confusing for students, especially those who do not have a science background.  I will be posting some supplementary videos in moodle to help explain these concepts.  They do go into more depth than your required to know, so when it comes to studying for the exam, stick to your lecture outline.  

 

Forum this Week

Lecture 3B will list the forum questions for this week.

As always you can use the forums to ask questions.  I really encourage you to use the peer teaching forum as well, and answer other student's questions.

Also, feel free to start your own conversation!  If you have a topic you would like to discuss, post a new discussion topic in the forums.

  

Now For the Lecture...

Have the lecture outline for Chapter 4-1 in front of you (You can print this off of moodle under Week 3).

Watch this Video Clip first, before going below to the little animated "movie".

Video Clip: Introduction to Covalent Bonds
about 6 minutes



The Study Questions this week include some information about a tiny animated "movie" that was created back in the late nineties.  It is not longer a movie but instead a webpage of pictures. (The link is below).

 

Why this movie?  When a plant makes glucose by photosynthesis, it captures the sun's energy in the bonds that join the atoms of carbons in glucose.  One of the purposes of this movie is to explain what bonds are.  Also, throughout this course we will be looking at the chemical structure of nutrients. The purpose of the movie is to introduce you to chemical structures, and explain what elements, electrons, and bonds are.


The Path to Inner Peace. A "movie" about covalent bonding.

 

Make sure you answer Study questions 1-12 in SQ 4- Part 1 while viewing the above "video".
