Inspired to Teach: Solar System to Scale

Solar System to Scale

Damn, this is one huuuuuuuuge universe we live in!

My class is studying the solar system, which I can't claim to be an expert in but love learning about-- I get so totally blown away and amazed by some of the fantastically un-mind-wrappable concepts and facts, and it's so cool to share things with students and see them be amazed as well. One of my students today was shocked to realize "we" were out in space, just like all the other planets. I asked her where she thought we were, and as the words "on the ground" came out I could see the light bulb flicker (and stay) on.

so I want to do one of those cool Solar System to Scale projects where the students can go outside and place (chalk? clay?) sun and planet models and see just how far apart everything really is -- any suggestions?

I did see that for most models, even the smallest, the nearest star is still apprx 4000 miles away! See what I mean? Wow!

I love to see how excited you are getting about the topic. I don't have any helpful hints about a scale model but you'll have to let us know how it works out. :); April 24, 2009 at 3:50 AM

Praise Song for the Day

Elizabeth Alexander

Inauguration Poem 2009

Each day we go about our business,
walking past each other,
catching each other’s eyes or not,
about to speak or speaking.

All about us is noise. All about us is
noise and bramble, thorn and din,
each one of our ancestors
on our tongues.

Someone is stitching up a hem,
darning a hole in a uniform,
patching a tire, repairing
the things in need of repair.

Someone is trying to make music
somewhere, with a pair of
wooden spoons on an oil drum,
with cello, boom box, harmonica, voice.

A woman and her son
wait for the bus.
A farmer considers
the changing sky.
A teacher says,
Take out your pencils. Begin.

We encounter each other in words,
words spiny or smooth,
whispered or declaimed,
words to consider, reconsider.

We cross dirt roads
and highways that mark the will
of some one and then others,
who said I need to see
what’s on the other side.

I know there’s something better down the road.
We need to find a place
where we are safe.
We walk into that
which we cannot yet see.

Say it plain: that many have died for this day.
Sing the names of the dead who brought us here,
who laid the train tracks,
raised the bridges,

picked the cotton and the lettuce,
built brick by brick
the glittering edifices
they would then keep clean
and work inside of.

Praise song for struggle,
praise song for the day.
Praise song for every
hand-lettered sign,
the figuring-it-out at kitchen tables.

Some live by love thy neighbor
as thyself, others by
irst do no harm or take no more
than you need.
What if the mightiest word is love?

Love beyond marital,
filial, national,
love that casts a widening
pool of light,
love with no need
to pre-empt grievance.

In today’s sharp sparkle,
this winter air,
any thing can be made,
any sentence begun.
On the brink, on the brim,
on the cusp,

praise song for walking forward
in that light.

I know it's probably copyright infringement, and I promise I'll teach my students to never, ever plagiarize, but these are awesome words-- probably just the weight and emotions of the day, but didn't you feel she was speaking directly to you?
