Wednesday Explorers ~ What's that under the ice?

Credit, Guillaume Grosbois

 When Guillaume Grosbois and Milla Rautio visited Lake Simoncouche, Quebec, they didn't expect to see much life swimming about beneath the frozen surface. Certainly not bright red zooplankton!

But there they were - red copepods buzzing about in the dark water. Turns out these copepods spend their fall chowing down on algae and building up their store of fat for the winter.

You can learn more about these curious creatures, and watch a video of them here.

Scuba Diving Spiders and Hugs

There are so many cool animals living on our planet, and so many ways to introduce their stories to children. Here are a couple released last fall that I really enjoyed.
theme: animals, nonfiction

The Secret of the Scuba Diving Spider ... and more!
by Ana Maria Rodriguez
48 pages; ages 8 - 11
Enslow, 2017

Roger Seymour and Stefan Hetz, animal biologists, are scouting Germany's northern countryside for the one-of-a-kind diving bell spider, the only spider that lives underwater.

It's not an easy job: the spiders are only as long as one to three grains of rice; they're hard to find in the water; and they are becoming rare because of habitat loss and pollution.  But the scientists find their spiders and we learn how the spiders build their diving bells.

What I like about this book: It's got more than diving bell spiders. There are whistling caterpillars - they whistle warning calls to their buddies- as well as bats that jam signals from other bats, and zombie ladybugs. Yes! Zombie Ladybugs! And cockroaches because if you're talking extreme bugs, you can't leave the roaches out.

Informative, fun, filled with unexpected surprises about weird creatures - this book's all that plus a hands-on activity at the end. And it's filled with photos that will engage kids and draw them into the strange lives of these critters.

How Many Hugs?
by Heather Swain; illus. by Steven Henry
32 pages; ages 4-8
Feiwel & Friends, 2017

Since snakes have no arms, nor any feet, 
they can slither about very discreet.
But this lack of appendages surely would make
an awkward affair if a hug from a snake.

From critters with no legs to those with hundreds, Heather Swain counts hugs. Using rhyme, she answers questions every kid has asked: how many legs does a millipede have?

What I like about this book: It's fun. It's imaginative. And it's filled with math, especially division. For example, if you have two arms how many hugs can you give at one time? Just one - which is half of two.  As the number of  legs/arms increases, the math gets a bit harder. But the concept remains the same: H = L/2 (the number of hugs equals the number of legs divided by two). So.... that millipede with 750 legs? I'll leave the math to you.

The other thing I like - there's back matter. A spread of facts about each animal and its leggy relatives.

Beyond the Book:

Find out more about Diving Bell spiders. Check out this video. Then head over to Ana Maria Rodriguez's website where you can find a teacher's guide for the book. There are plenty more activities there plus a crossword puzzle.

How many hugs can you find in your neighborhood? Check out the animal wildlife living in and around you. Jot down each animal you see and how many legs it has. Then calculate how many hugs it could potentially give at one time.

Invent a way you could live under water. How would you collect and store air to breathe? 

Today we're joining the STEM Friday roundup - and we're also joining others over at Perfect Picture Book Friday, an event in which bloggers share great picture books at Susanna Leonard Hill's site. She keeps an ever-growing list of Perfect Picture Books. Review copies from the publishers.

Wednesday Explorers ~ Icy sounds


It's been cold the past couple weeks, with ice forming in road ruts, coating gravel, or sometimes falling like glitter from the sky.

Last year around this time NPR produced a fun piece on how ice sounds like Star War blasters. Have fun! And spend some time listening to ice wherever you happen to be this winter.
