 World
of Wonders
by Spencer
Christian
Where
in the world do you live? I mean that LITERALLY –
where, in this big space called the universe, do you
live? Well, for starters, your "planetary" address is
Earth. And how much do you know about the natural forces
that are constantly at work on your planet? Do you ever
wonder how clouds form, why the sky is blue, what makes
the wind blow? Or, do you wonder what causes earthquakes,
why volcanoes erupt, how lightning strikes?
In this column called the "World of Wonders",
I will regularly provide answers to questions like the
ones above; and I'll describe experiments, which you
can perform at home and at school, that will show you
vividly how the wondrous and powerful forces of nature
work to keep our planet "alive". And, from time to time,
we'll venture out beyond our own planet to examine the
awesome spectacle of the universe.
