Air pollution earth science discussion, science homework help
Group Discussion Prompt: Review
the air pollution data you collected in the Lab Report for Discussion,
and design an experiment that allows you to measure air pollution. Use
the discussion board to share your design and the data you collected
with your classmates. Describe your experimental design.

Instructions for lab in order to complete discussion.
Your assignment for this laboratory is to design
your own experiment to test for air pollution. It is all up to you. You
decide what you are testing for, where you will test for it, and how you
should gather and identify the types and sources of air pollution. Keep
careful notes and make sure you follow scientific methods so that you
can answer the questions on your Lab Report for Discussion before
joining the Threaded Discussion Board Activity.
Before you form a hypothesis and design your
experiment, consider your location and your materials. If you live in a
city, you might have an easier time finding pollution as compared with
someone in the country, but there are small amounts of air pollution
everywhere. Take a look around the outside your home. Are your windows
dirty? How did they get that way? See how much dirt you can pull off of
an outside wall using the sticky side of a piece of tape. You could also
see how much dirt you can collect off surfaces with a paper towel and a
cleaning solution. If you live in the city, you could ask a friend in
the country to do the exact same procedure and compare notes.
You could also try to collect pollution using the
glass slides and the petroleum jelly from the K12 materials kit. Smear
petroleum jelly on the slides, and then place the slides in different
places. How much dust and dirt sticks to each slide in a week? Can you
find more pollutants on a busy city street as compared with quiet roads?
What about rain? Can you detect air pollution by examining rainwater?
