1 Every time you step outside, you are under attack. 2 Which you may not
know what is hitting you, but the attack is truly happening. 3 Invisible storms
of sky dust rain down on you all the time. 4 It does not matter if the sun is
shining and the sky are bright blue. 5 The dust is still there.
6 Sky dust consist of bug parts, specks of hair, pollen, and even tiny chunks
of comets. 7 According to experts, 6 million pounds of space dust settle on
the earth’s surface every year. 8 You will never notice it, scientists, however,
are collecting it in order to learn more about weather patterns and pollution.
9 Using sophisticated equipment like high-tech planes and sterile filters to
collect dust samples.
10 Dan Murray, a geologist at the University of Rhode Island, has began a
new project that invites students and teachers to help collect samples of cosmic
dust. 11 Murray says that collecting the dust particles are quite simple. 12 It
starts with a researcher setting up a small, inflatable swimming pool. 13 Next,
this investigator leaves the pool out in the open for 48 hours. 14 Finally, the
researcher uses a special type of tape to pick up whatever have settled over time.
15 The tape is put into a beaker of water to dissolve a microscope is used to
analyze what comes off the tape. 16 The information finded there will help
scientists predict insect seasons, measure meteor showers, or even catch signs
of global warming.
