Week # 6 - March 12 - 19

This past week is/was probably a little busy for you - working on both a lab 2 and an issue 2.

Issue 2 deadline is extended another week - this will be the common practice to let issues carry over into the second week.

The following assignments are now past due:

Topic 5 On-line Lecture Discussion

Laboratory 2

Sixth Week Assignments due on March 19:


1. On-line Discussion: Topic 6 Energy Resources - Fossil Fuels. This week one question has been assigned, the second and third questions are your choice.

As part of Topic 6 there is a speical assignment "Personal Energy Resource Use Assessment". This asks you to keep track of gasoline, electric, and natural gas usage. At the end of the assignment is a method to calculate your personal production of carbon dioxide - greenhouse gas.

2. Home Lab # 3:This week you need to get started early but actually the entire lab is completed from graphhics and info given online. The HTML version, HOME Lab # 3 - Absorption of Solar Radiation - Greenhouse Effect. Be sure to look at the HTML version, since there is a pre-lab on-line involving different types of solar radiation, changes in energy, and the Greenhouse effect. This can only be completed using the online version to bring up graphics. There are also a couple of diagrams for the lab set-up. There is an optioinal extra credit part if you want to do something similar at home.

Here is the Lab menu page that has other versions of the lab.

 

3. For those that like to work ahead as time permits, EXAM # 2 is now available on-line and is due by April 2.

Here is the Exam menu page that has other versions of the exam.

 

4. Rain!!! have you got your pH samples yet? You will need them for Lab #4. There has been much rain lately so be sure to get a sample - no excuses for not having the required number of samples.
This week is a good time to go outside, collect a rain sample, and then measure the pH using your acid rain test strips.You may also be out and about and measure the pH in various natural bodies of water - lakes, ponds, streams.

See the lab for details, since you need 4 or 5 samples for full credit, you can not wait until the last minute to do this.
