Rats 102 - First Things First
Somebody somewhere will mention the tail.
"It's so gross and disgusting," they all seem to say,
But let's try to see it a different way.
Their tail is so awesome, to do what it does,
Keeping their balance on wires up above.
It's brilliant and amazing, that long skinny tail,
It steadies them steady on the narrowest trail.
To see it in action is a fabulous sight,
with expert precision it shifts left and shifts right.
Just crossing a rope can be quite a big challenge,
But thanks to the tail, the rat keeps his balance.
Its a matter of needs and its needs are quite plain,
If it falls from above it will feel all sorts of pain.
Its comes down to a science called Rotational Inertia,
So stop worrying about it. The tail ain't gonna hurt ya.
"But, Liam, just look! It just isn't fair!
Why does that tail have to look naked and bare?"
A very good question and thanks for being so patient,
It's the simple little science of Thermoregulation.
When the rats getting too warm, the tail cools it down,
It helps it stay cozy the whole year round.
Blood vessels expand when it's getting too hot
That's Vasodilation. Is that cool or what?!
Vasoconstriction is the opposite way.
The tail keeps the heat from escaping away.
Blood vessels get smaller and trap in the heat.
It's a clever little trick that just can't be beat.
So next time someone tells you how gross their tails are,
You're armed with the knowledge to be a rat-star,
to stand on your soapbox and passionately wail,
"I KNOW WHAT IT'S FOR SO I LOVE THAT TAIL!"
To finish, here's a thought. As teachers, we urge our students to look beyond the flesh and to see others for who they really are...
