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.
