Why is the sky blue?  Many aspects of light and all its wonderful colours have amazed, puzzled and inspired us.  This year's National Science Week's theme is LIGHT - making waves.  So, as a lead-up to this event in August, Science Rhymes is offering an inspirational presentation to schools in the Cairns region titled THE SCIENCE & POETRY OF LIGHT.

(The science of why the sky is blue, is in the poem below).

Squiggle & Bump
by Celia Berrell

Within the spectrum of visible light
the colours all have their own unique strides.
When angled through water a rainbow appears.
When flying together they come out as whites.

Imagine a man with very long legs.
Only six steps to get from here to there.
Red has the longest wavelength of light.
His frequency's low and his energy's spare..

Imagine a child with very short legs.
It takes sixty steps to do the same trip.

Violet's shortest, compared to Red.
Her frequency's high and her energy's hip.

Red, Orange, Yellow are all pretty long
and happily stride through our atmosphere.
But little legs Blue through to Violet
bump into the molecules in the air.

Those molecules hug them, just hastily
then send them off on a different course.
They criss-cross the gases within the air
being hugged and bumped with gentle force.

So when you look at the daytime sky
you'll see the short wavelengths criss-crossing by.
Since longer-legged colours have all got through
the sky will appear as a beautiful blue.

The Science & Poetry of Light
for upper primary school students in the Cairns region


Registered with National Science Week,

this project aims to provide private presentations within Cairns region's primary schools, to inspire students in creating their own poems and prose about light and light technologies, ready to recite / publish as part of the celebrations for National Science Week (15-23 August 2015).

When preparing this eNewsletter, National Science Week had not yet published this event.

CSIRO & Scientriffic Poems

This July, CSIRO is amalgamating their two bi-monthly science magazines for children into a new six-weekly publication called Double Helix (age 9-13).  The final Scientriffic poem will be Breakfast Under the Seabed.  

But don't be too sad, you can still view older poems via the free PDF download Let The Show Go On.  It features 12 previously published poems and includes links to further science information on each topic.
This diagram from NASA shows how tiny the segment of visible light is, compared with the other forms of electromagnetic radiation. Scientist Alan Beech writes mnemonic science poems (to help us remember all those scientific terms!). Here's his EMR poem (below).
Electromagnetic (EM) Wave (Ray) Spectrum
by Alan Beach

Waves most penetrating gamma,
Minute but an energy hammer.
X-ray waves see through skin substrate
But our bones cannot penetrate.
Ultra violet rays, UV,
Shorter than violet waves we see.
Violet view then to indigo go,
Blue then green are next in the row.
Yellows like lemons to oranges change,
Red, longest waves in the visible range.
Longer than visible waves, infra-red,
We cannot see them but feel heat instead.
Very long EM waves we know
Carry media, TV and radio.
Would you like to see your own poem on the internet?
This year we are especially seeking poetry about LIGHT of course! 

If you have written a short poem about science, nature or the environment, send it to for consideration to be posted on the Your Poems page on the Science Rhymes website.
