Homework

Read Section 14.1, 14.2 Pgs. 488-495

Answer the following: Section 14.1-  Pg 514-515 Questions 1, 3, 5, 10, 11, 12, 13, 15, 17, 18, 21.

and Section 14.2 25, 26, 28, 31, and, 32. 

Homework is due March 1st and 2nd.  

Note: Section 14.3 will be covered with another unit.  DO NOT DO Section 14.3 at this time.  

This is the website where you can find more information about water quality

http://www.h2ou.com/h2wtrqual.htm

Also you are to view the power points accesible once you log in as student.   Download the files, run them in your computer and copy the notes.  Most important, you need to copy the defenitions of each slide of each slide show.  We already covered Part I but you need to look at Part II and Part III.

Make sure to download the files and then run them from your computer. 

You will need to have MS Power Point to run these files. 

If you do not have it, you can download the Power Point Player from the Microsoft Website.
