Materials were distributed for the first time in class on Thu., Aug. 25.

Click on one of the following links if you need an extra copy of the report format, the instructions for the experiment, or a data collection sheet.  Check in class if you need a new piece of steel wool.

Click on this more information link to learn more about Expt. #1.

Start the experiment at a time (the weekend is ideal) when you will be able to check it a few times at fairly frequent (hourly perhaps) intervals for a few hours.  Don't wait until the last minute to start this experiment because it may take several days to run to completion. 

Try to complete the experiment well before the report due date.  Once you have collected your data, return your materials and pick up the supplementary information handout.  This handout will help with the analysis portion of your report.  Your name should turn this rust color when you have returned your materials.  An X in front of your name means you turned in your report.

In a few cases a couple of students are sharing the materials.  You should each perform a separate experiment.  You will need a new piece of steel wool (available in class) every time you restart the experiment.

Unless noted otherwise, reports are due in class on Tue., Sep. 20.
