Air Junk: Specks, Flecks and Particles in the Air

image
Dust turns sunsets
orange and red.
It does other
good things, too.
But dust and other
particles can also
make you sick—
especially if you have
allergies or asthma.

We're going to
look for this junk
in your house.

Click here to
bring up a page
you can use as
a pattern for the
dust collectors.

Here's what you need to make six airborne junk detectors
  1. An 8" x 10" (205 x 255 millimeters, or mm) piece of shoe-box cardboard or stiff paper from a file folder.
2. Six pieces of sticky stuff. Sticky labels or transparent tape work fine. Each piece should be about 1-1/2" x 3-1/2" (40 mm x 90 mm).
3. One light string per collector, 12" (300 mm) long.
4. Tape to hang the collector strings.
5. A magnifying glass (if you have one).


 Here's All You Do:
  1. Print out the pattern page.
2. Cut out six collectors, using the pattern from the page.
3. Fold each collector and cut out the inside window. Then flatten the collector.
4. Write the location and starting date and time on each collector.
5. Hang the collectors wherever you are curious about the air. Or use these suggested locations:
 
  • Above your bed, near where you breathe.
  • On the inside or outside of a window.
  • Near a heating vent.
  • Above the cooking stove.
  • On a wall near the floor or ceiling.
  • On your main entry door.
  • Under a tree.
6. Cover the window on the collector with the sticky label or tape. Put the sticky side up or out.
7. Wait a couple of days and take the collectors down. Write the ending time and date on each. Don't touch the sticky stuff!

Now let's look at what you found!
