Riddle: When is a star not a
star? When it's a shooting star!
|
What are Meteors?
Rocks from space can fall through our sky
toward the ground with a fiery glow. We sometimes call these bright
objects "shooting stars". Of ocurse they are not stars but meteors.
Tiny meteors from space, usually dust from
the tails of comets, come into the atmosphere. These micro-meteors
are so small and light that they do not always burn up as they fall to
Earth, they stay trapped in air currents high in the atmosphere until
washed down to the ground in rain drops.
If you want to impress your teacher, take
to class some "shooting-star dust" that is out of this world!
Try this:
- Collect a bucket of rainwater within a 2 week
span of the dates below.
- Filter the water (coffee filters will do) and
leave to dry.
- Use a magnet to pick up any iron containing
material. Micro-meteors usually contain iron so you can seperate them
from carbon or soot, etc. that may be part of our normal air pollution.
