"Bioluminescence is the most widely used form of communication on the planet."--W.H. Beck, Glow: Animals with Their Own Night-Lights
I've read this sentence ten times this week, as part of my Book Nook time with our kindergarten classes. There are some weird and wonderful facts presented in this great nonfiction book, but the quote above is my favorite pause-and-comment point during the read-aloud.
Think about what this sentence means, I tell the students as I repeat the words.
It means that that are more living creatures who use light to talk with each other than there are
people who use words
lions that roar
dogs that bark
cats that meow
crickets who chirp
birds who tweet
all the sounds that creatures make to communicate with each other.
Light wins over sound, mostly because at least half of the living creatures on earth exist underwater. I find these facts fascinating, leading to thoughts of the dark, silent depths of our oceans and the amazing creatures scientists are finding there. I'm also looking forward to the return of the fireflies in our yard and park beyond.
Bioluminescence--light chatter-- is the word of the week.
