More BUG Books!

One can never have too many books about bugs! Here are a few more from my book basket:

There's a Bug on my Book!
by John Himmelman
32 pages; ages 4-7
Dawn Publications, 2017

The best thing about summer is reading outside. That's what this book is all about: sitting on the grass with a ...
"Hey! there's a bug on my book! It's a beetle."

Okay, we can handle that. Just puff a breath of air on it to get it moving. Now, back to reading. Yikes! now there's a snake slithering across the page.

What I like about this book: it invites readers to tilt the book (so the snake slides back into the grass), to nudge a bug, to be patient while a slug meanders across the page. At the same time, John Himmelman shares observations about the insects, spiders, worms, and other .... what's that? A frog just plopped onto the page! Another thing I like about this book is the back matter. Four Pages! That's where you learn more about each critter that slithered, slimed, hopped, wiggled, and plopped across the pages of the book. There are also activities that explore how bugs move, habitat, and "design a bug". You'll find more buggy activities at the Dawn website here.

Explore My World: Honey Bees
by Jill Esbaum
32 pages; ages 3-7
National Geographic Children's Books, 2017

"Look, a honey bee!" Easy to read and understand, the text describes the life of a honey bee. There's nectar-collecting, loading up the pollen baskets (which, we learn, can be a messy job), and carting the food back home. The hive is a busy place, with so many sisters and a queen, and there's lots of work to do in hive as well. We see the bee life cycle, meet a newly emerged bee who is immediately given a task: clean your room! Back matter includes more details about honey, pollination, the waggle dance, and a maze.

You might wonder why NGK writes "honey bee" rather than "honeybee". That's because they're following the rules of entomology: a honey bee is a kind of bee, just like a house fly is a kind of fly. On the other hand, a dragonfly (one word) is not a fly at all.

Incredible Bugs (series: Animal Bests)
by John Farndon; illus. by Cristina Portolano
32 pages; ages 8-12
Hungry Tomato, 2016

This is a fun, browsable book with a table of contents so you can find what you're looking for fast (if you want). Sections include smartest bugs, communication, special senses, builders, tool users, teamwork, migration, and special skills. You'll discover maze-solving spiders, dragonfly flight instruments, and which bug can leap tall buildings in a single jump. Text is accompanied by cartoons and photos.

Wednesday Explorers Club ~ Smelly Bee Feet

There are bees all over my garden! Bumble bees, carpenter bees, tiny metallic green bees, hairy gray sweat bees, and lots and lots of honey bees. Which means, I have lots of bees to watch when I get tired of weeding.

One of the things I've been wondering is how bees can tell whether there's food waiting inside the flowers they're about to land on. Sure, honey bees dance out directions to their sisters about where the best nectar can be found - but what if another bee got there first?

Turns out that bees - at least bumble bees - can tell whether someone else has visited a flower by the stinky feet print left behind. Yup. Bees have smelly feet, say researchers at the University of Bristol. This means the bees can tell whether they've visited a flower before, and even whether one of their nest-mates has been there. You can read the entire study here.

Great American EclipseToday!

The Great American Eclipse is happening!

If you plan to view the sun directly, make sure you have special filters (eclipse glasses) that meet the  ISO 12312-2:2015 standard. Even with those, don't spend a lot of time looking at the sun.

The safest way to watch the eclipse is with your back to the sun. Make a projector and watch the images. If you project the image onto paper, you can trace projections of the eclipse over time so you have a permanent record of your day.

Here are Five Ways to View an Eclipse (from Science Friday)

Here's some Eclipse Science (from last Wednesday)

I'll be watching the eclipse using my favorite pinhole projector: a hole poked through a paper plate. (Though I might use the cereal box, too)

Have fun and be safe! Remember to put on sunscreen and don't look at the sun without your special eclipse filters.

My Awesome Summer

My Awesome Summer,  by P. Mantis
by Paul Meisel
40 pages; ages 4-8
Holiday House, 2017

P. Mantis had a wonderful summer, full of bird-watching, hide-and-seek, fine food, sibling rivalry, and flight lessons. There are a few scary moment, like the time she almost got eaten by a bat, and narrowly escaping spider webs. But for the most part it was a summer to remember.

What I like about this book:
It's fun to read! Written from the point of view of a praying mantis, it's set up as diary entries. For example:
June 2
All the aphids are gone. I'm hungry. Growing so fast! I ate one of my brothers. Okay, maybe two. Fine dining? Or sibling rivalry? Sometimes it's hard to tell the difference. P. Mantis also reveals her most important trick: how to be still and look like a stick. This gets her out of a lot of dicey situations.

I also like love that what would usually go into back matter has been put on the end papers. Small-ish chunks of information about praying mantises and their ecology are accompanied by illustrations. The end pages are where you learn what mantises like to eat, how they use camouflage to hide from predators, flight, and laying eggs. That's where cool websites are and a very tiny glossary.

I like the cover, too. Who can ignore a face like Mantis's? Plus the monarda! Heading out to my garden to see if any of her cousins are hanging out amongst my flowers.

Beyond the Book:

Go on  a Mantis Expedition. Explore flowers and shrubs and tall-grass areas to see if there are any mantids hanging about. Remember to take along something to sketch with, or a camera. Things to observe:
  • how big are the mantids you find?
  • what colors are they?
  • do they fly?
  • watch their behavior for awhile. How do they hunt? 

What do mantids do during a solar eclipse? On Monday there will be an eclipse of the sun. If you live in North America you'll see partial or total eclipse. Check the Wednesday Explorer Club post for more. 

Check out this cool interview with StoryMakers. You'll learn how Paul Meisel met P. Mantis, and how he does his illustrations.

Read this Mantis profile over at National Geographic Kids.

Write about your awesome summer. When I went to school, every fall we had to write a story about what we did that summer. Don't wait. Get a head start ... and if you're feeling particularly creative, write a story from the point of view of an animal who spent the summer nearby.

Wednesday Explorers Club ~ Solar Eclipse Science!

photo from NASA - eclipse seen in space

The Solar Eclipse is coming - Monday, August 21 - and if you live anywhere in North America you'll see at least a partial eclipse. A solar eclipse is when the moon passes between the earth and the sun, blocking out part (or in a swath of lucky locations, all) of the sun's light.

We all know - or at least we should know - that looking directly at the sun can damage our eyes. This holds true for solar eclipses, too. So even though the moon will block the sun's light, you can't watch the eclipse by looking at the sun -

 UNLESS you have special eclipse-viewing glasses.

Eclipse viewing glasses have special filters that protect your eyes. Regular sunglasses are NOT adequate. If you don't have a pair of special eclipse viewing glasses, check your local library. Many libraries are providing glasses and holding fun eclipse viewing parties. Find out more about eclipse safety here.

Those of us who grew up in the last century (context: it was only 18 years ago) learned a cool - and cheap - trick for viewing solar eclipses: make a projector. Instead of looking at the sun, you project the sun's image on a sheet of paper (or a white wall) and watch the moon move across the sun's image. The easiest projector to make is a pinhole projector.

How to make a pinhole projector: Find a piece of cardboard in your recycling bin (clean pizza box, cereal box, large postcard, old spiral notebook cover, even a couple paper plates). Then use a thumbtack, nail, or even sharp point of a pencil to poke a small hole through it. With your back to the sun, hold the cardboard over your shoulder and project the image onto a piece of paper on the ground or a white sidewalk.

Eclipse Science: 

What is the best size or shape of hole for a projector? The suggested size for a pinhole is 1mm, with a perfectly round hole. Will larger holes project just as well? Punch or cut a series of holes of different sizes so you can compare them during the eclipse. Which ones provide clear images? Which provide fuzzy images?

Does hole shape matter? What if you cut a triangle or square?

Does distance of your projector from the ground matter? Compare images when you hold projector close to ground, knee distance, waist distance, shoulder distance... attached to the handle of a rake and held high above the ground...

How does the world change during a solar eclipse? Before the eclipse make some notes about the temperature, how the air feels on your skin, what the surrounding environment looks like, what bird and insect sounds you hear. Continue to jot down observations as the eclipse progresses, and especially when it reaches its darkest. 

More projectors: Got a cereal box? You can turn it into an eclipse viewer with a minimal amount of materials and time. Here's how. Or try making an eclipse viewer from a tube. Instructions here. (Experiment: does tube length matter?)

Remember: it's summer, so put on your sunscreen because you can get a sunburn even during an eclipse.

Birds and bugs

So... you may have noticed over the summer that I love bugs. Ants, bumble bees, clear-winged hummingbird moths, beetles of all colors and kinds! And I found a cool field guide perfect for kids who want to learn more about insects.

Ultimate Explorer Field Guide: Insects
By Libby Romero 
160 pages; ages 8-10
 National Geographic Children’s Books, 2017

This is so much more than a field guide. Introductory pages tell where to find insects, how to be safe around insects (avoiding stings, bites, and defensive chemicals), and how to protect insects. Each page introduces an insect, giving its scientific name along with notes about ecology and behavior and photos. There are text boxes noting things to look for, listen to, plus hands-on activities (how to draw a dragonfly), plus plenty of “Insect Inspector” side bars. Every few pages you’ll find an “Insect Report” focusing on specific features: wings, how to tell an insect from a “bug”, and the art of insect deception.

Helpful back matter includes a photographic “Quick ID Guide”, a list of books and apps for discovering more, a glossary, and index. And all of that is in a pocket-sized guide with tough, flexible covers.
Bird Braniacs
by Stacy Tornio and Ken Keffer;  illustrated by Rachel Riordan
104 pages; ages  5 - 13
Cornell Lab Publishing Group, 2016

The subtitle for this book is "activity journal and log book for young birders." It is meant to be written in, drawn in, shared with friends. Part activity book and part birding journal, Bird Brainiacs is the perfect book to tuck in a backpack, or toss in the picnic basket when heading off to the park. There are quizzes, “mad-lib” fill-in-the-blanks, games, nature challenges, personality questionnaires, word scrambles, and bird facts. I love the hands-on science stuff: a do-it-yourself bioblitz, bird count, and nest-watching. There are enough bird-log pages to get you started on a summer’s worth of birding plus some how-to-draw pages for the doodler in us all. I know the age range is for up to 13 years, but heck, this looks like fun for the whole family.

Wednesday Explorers Club ~ Hummingbird Moths

The other day the teasel were busy with bumble bees. There, hovering with them was something else. It hovered sort of like a hummingbird, but the black and yellow stripes made it look like a huge bumble bee - plus hummingbirds don't have antennae.

It's a hummingbird moth, also called hummingbird hawk moth. Look closely and you can see a tiny tail fanned out beneath it. And if you hold still, you can hear them hum, just like a hummingbird (though a moth has never buzzed me yet). Around here they tend to visit monarda and teasels, and they also like phlox, honeysuckle, and verbena.

Here's a video showing a hummingbird moth collecting nectar

Want to learn more? Check out this article by the US Forest Service, and a wonderful collection of photos here.

As you head out on explorations this week, remember: things are not always what they seem. Slow down, look closer - and take notes.

Up! Up! Up! Skyscraper

Up! Up! Up! Skyscraper
by Anastasia Suen; illus. by Ryan O'Rourke
32 pages; ages 3-7
Charlesbridge, 2017

Dig, dig, dig!
Pour, pour, pour!
Pound, pound, pound!

What's going on behind that tall board fence? Put on your hardhat and let's find out.

Machines and people work together to build a skyscraper. So tall it touches the clouds. So if they're building up, why are they digging down? Because tall buildings need sturdy foundations.

Anastasia Suen takes readers behind the fence and into the world of a construction site. Active language engages kids in what's going on, and additional text explains why. Bolt by bolt, beam by beam, we travel up, up, up to the top of the building. Once the skeleton is completed it's time to put the "skin" on - the metal and glass panels that hold everything in. And then, at last, with a fold-out page that extends high above the others, we see the finished skyscraper.

Beyond the book:

Then pull out the bin of blocks and build, build, build your own tower!
