Rainbow on the cliffs at Sarclet,
east coast of
SCOTLAND
Black rock cliffs one hundred feet above the blue,
specked white with gulls, and Fulmars;
Skuas and Guillemots wheel like loose seeds
making land and sea one.
....
Unexpectedly a perfect rainbow appears,
arching from the green cliff top,
over and down to the cobble beach where Austin
stands.
"Austin, get the pot of gold!" we shout.
As we are spread out along the path,
the prismatic colors appear to each of us
in a slightly different place so
of course he is utterly confused.
It is clearly a most brilliant bow and
so close I am sure I can touch it. The
sun
brightens and momentarily an echo of color
arches in reverse just above the first. Every
color shines
intensely all the way into the blue, indigo and
violet,
a perfect giant of the ones I create
on the blackboard for my students.
We smile at one another and feel magical.

Your task for this unit is to learn about the
Electromagnetic (EM) Spectrum and the many different kinds of 'energy' it

and stars. You will choose one part of the EM spectrum, investigate it
more in depth, and report what you learn to your classmates.
