TEACHER HELP
The numbers below corresponds to the numbered steps
in the teacher lesson plan.
1. Self explanatory
2. See MONITORING SITES for particular carbon monoxide sites and the corresponding temperature and demographic sites. Assign a particular site to each group. If you have a small class pick sites that are demographically different from each other so that comparisons can be made later.
3. Data collecting should take place twice a week ( or daily). We recommend students collect data Tuesday through Friday and never collect the day after a major holiday. Hopefully this will avoid collecting data that may distort results. Data collecting should take place from October through March. When the student goes to the MONITORING SITE he or she should click onto their site. They will see links to their carbon monoxide site in addition to links for temperature and demographics.When the student clicks onto the carbon monoxide site he or she will see a dial representing carbon monoxide levels at their site. The data is given in units of PSI. Go to PSI for an explanation on what this unit refers to. Students can record their data in PSI. The student needs to record the date, time and level of the most current carbon monoxide reading . In addition to this they need to record the maximum and minimum levels and the time they correspond to. The maximum and minimum values represent the max and min’s for the 24 hours prior to the time of the current reading. Note: If the weather sites are not available try Accu Weather.

5. The data collected can be used to create many
graphs. We suggest the following :
Graphs are grouped in pairs to assist analysis.
a. Current
CO level /temp on y axis vs date on x axis
b.
Max CO level/temp on y axis vs date on x axis
c.
Max CO level on y axis vs time of day on x axis
d.
Min CO level on y axis vs time of day on x axis.
e.
Current CO level on y axis vs temperature on x axis
f. Max CO level on y axis vs temperature on x
axis
Meteorological data such as wind speed, air pressure, humidity can be used to evaluate specific highs or lows.
6. We suggest for further work
students complete a question and answer sheet provided in the student Lab Report
section. Also the teacher could have students compare their report with another
groups. The teacher should pick groups from demographically different regions for
comparison. Such as, urban vs rural, suburban vs industrial, etc.
