Science Probe II Technology Activities
There has been much publicity in past years about the existence
of an ozone hole in the upper atmosphere. However, recently there has
been little said about it. Why is this so? Conduct an Internet search
a.What current research has learned about the ozone hole?
b.What chemical reactions are believed to cause it?
c.How large is it?
d.How much does it change from season to season and year to year?
e.What is predicted about it in the future?
It might also be helpful to correspond through e-mail or
talk in a web discussion site with an atmospheric scientist or an environmental
specialist to get your answers. Prepare a multimedia presentation to inform
your classmates of what you have learned. Below is a web site to get you
The Ozone Hole Tour
Activity 20C – After you have selected
the material to research in this activity and listed the ingredients,
conduct an Internet search on the product and its ingredients. Connect
with the web page of the manufacturer to obtain information about why
these ingredients are used in the product. Use a word processing program
to record your answers to these questions and what you think each chemical
might have on the biotic and abiotic environment and how any pollution
from the product could be eliminated. Prepare a presentation to share
what you have learned with your classmates.
Activity 20E – Use a spreadsheet
program to make your data tables for Parts II and III as directed in this
activity. Record the data from Figure 20.14 in the spreadsheet data table
as suggested in the activity. Use the graphing feature of the spreadsheet
program to plot the Pollution level (in PPHM) on the vertical axis and
Time of day on the horizontal axis. Record the data from Table 20.3 in
the spreadsheet data table as directed in the activity. Use the graphing
feature of the spreadsheet program to plot the CO level (in PPM x 10)
on the vertical axis and Time of day on the horizontal axis. Print the
final spreadsheet data tables and graphs, and secure them in your SCIENCE
PROBE Logbook where you will answer the discussion questions.
Activity 20F – Use an Internet search
to find out about the greenhouse effect, what are considered to be greenhouse
gases, and what impact an increased greenhouse effect may have on your
life. Use a presentation, graphics, or similar program to do your presentation
as directed in the activity.
