Eclipse Chaser

Science in the Moon’s Shadow

by Ilima Loomis
with photographs by Amanda Cowan

Houghton Mifflin Harcourt, 2019. 80 pages.
Review written April 27, 2020, from a library book
Starred Review

Eclipse Chaser is part of the wonderful Scientists in the Field series, which uses the tagline, Where Science Meets Adventure. These books show actual scientists on actual expeditions. They explain what the scientists are trying to figure out, the importance of their endeavors, and the obstacles, challenges, and successes they meet with.

This book features the scientist Shadia Habbal and her expedition to get vital scientific information during the Great American Total Solar Eclipse of 2017. This makes the book especially pertinent, since many of the readers, like me, will have experienced that eclipse themselves.

It tells about the many other total solar eclipses Shadia has seen, how that gives her an exceptional look at the sun’s corona, and about some of the breakthroughs she has discovered in her previous work. Shaddia is studying solar winds, and to do that, she uses special filtered cameras that show the location of certain elements in the sun’s corona, as well as photos of certain iron ions that give the temperature in the corona where they’re present.

The book is full of photographs. There’s plenty of drama about setting up all the expensive equipment to take photographs in a short period of time. Since I was present for a solar eclipse in Germany in 1999 where clouds covered the sun in the last minute before totality, I was extra appreciative of those worries. We were told about past expeditions where weather wiped out all their plans.

It’s all fascinating information that helped me understand better why solar eclipses are so important for scientists. There are several photos of the sun’s corona taken during eclipses to help you grasp what they can find out and understand what they’re talking about with the term “solar wind.”

A map in the back of paths, dates, and durations of solar eclipses between 2011 and 2060 says there’s going to be another total solar eclipse in America in April 2024. We’ll want to prominently display this book on our library shelves when that event approaches.

Code Cracking for Kids

Secret Communications Throughout History, with 21 Codes and Ciphers

by Jean Daigneau

Chicago Review Press, 2020. 129 pages.
Review written December 29, 2020, from a library book
Starred Review

This is a nice solid book on codes and ciphers for upper elementary through middle school kids. It’s got activities – the 21 codes and ciphers from the subtitle – but it’s also heavy on the history of how secret communication has developed, all the way up to talking about how cryptography works today and how important it is in computer applications.

The library got three new books on codes at the same time, and together they make a nice picture of how kids can use codes but also how the world around us uses them. This one doesn’t have any cartoon illustrations, but uses historical photographs, so it’s got a less playful approach, while still full of ideas for how kids can try out what they’re learning.

In fact, the first activity this author suggests is making a cryptologist’s kit – assembling materials used in making and breaking codes into a backpack. As more activities are presented, they usually suggest something to go into your cryptologist’s kit.

The codes and ciphers presented here are rooted in history. They begin with spies and the codes they used, as well as thinking of other languages and writing systems as a kind of code. Some of the historical items the reader gets to make are an Alberti Cipher Disk, invisible ink, a Jefferson Cipher Wheel, a message hidden inside an eggshell, a St. Cyr Slide Cipher, semaphore flags, and a secret book compartment.

When I was in junior high, I’d read about the tap code used by American POWs in Vietnam and used it to send messages with my friends. This is the first book I’ve seen that includes that cipher. In general, this one has more to say about codes in the present day than the other books I’ve read for kids.

There’s a lot of good information here, and lots of ideas that interested kids can take much further.

2021 Mathical Honor Book, Grades 6-8

I’ve always thought codes and ciphers are fascinating, from the time I was a kid right up to the present when I made some videos showing how to make interesting ciphers using mathematical concepts.

When I made the videos last Spring when the library was closed for the pandemic, I didn’t find too many current books on making codes, but that situation has been remedied. This book is a nice solid selection to fill in that gap. Written for elementary to middle school kids, it gives a history of encoded messages along with explanations of ciphers and codes the reader can use.

Each chapter has a message to decrypt, and the book ends with a message for the reader to solve and email the author if they figure it out. A few clues are given, and it’s a nicely appropriate historical code used.

The book starts with steganography – hiding a message in some way – and the Caesar cipher and continues with things like Benedict Arnold’s book cipher and Thomas Jefferson’s wheel cipher up through a puzzle encoded in a statue in front of CIA headquarters and the use of prime numbers in computer security.

Even when they get deep into the history of clandestine messages, they do give the readers chances to crack the codes.

There’s plenty here to get kids intrigued, and one thing I love about code-making is there are lots of jumping-off points from this book.

Review of The Magnificent Migration, by Sy Montgomery

The Magnificent Migration

On Safari with Africa’s Last Great Herds

by Sy Montgomery
with photos by Roger and Logan Wood

Houghton Mifflin Harcourt, 2019. 162 pages.
Review written April 15, 2020, from a library book
Starred Review

This visually stunning book has taught me so many things about “the greatest of all mammalian migrations” – the wildebeests of the Serengeti. Who knew that the gnu is so hugely important to earth’s environment? I didn’t before reading this book, but I do now.

Here’s a small section from the Introduction:

Like no other event in nature, the wildebeest migration defines wild Africa. The extravagance of their number stupefies: one and a quarter million wildebeests, in separate herds of tens of thousands, all on the move at once, accompanied by hundreds of thousands of zebras and gazelles. It is the largest mass movement of animals on land.

The sheer number of so many animals in motion is a dazzling spectacle. It is a force like gravity, or rainfall – a force that transforms, nourishes, and renews both the land over which they travel and the other creatures who gather in their wake.

Sy Montgomery does insert herself into the book – this is basically the story of her safari to observe wildebeests, traveling with the world’s foremost expert on them. But that added a little drama to the story – would they find a large group of wildebeests, since they don’t travel the same route from year to year? And we learn so much about wildebeests and other animals of Africa along the way. In hearing where they traveled to find the wildebeests, we understood more about the migration and about rutting season for the animals and about all the other animals affected by the migration.

The photographs in this book, taken on her safari, are amazing. The format is extra large, with spreads big as a picture book. There are photographs on every page, but there’s also plenty of text. I ended up being surprised how long it took me to read, because it’s much more than a picture book. Those big pages, which are so nice for the photographs, also hold large amounts of text.

There are many sidebars throughout. They include information about other animals that migrate, other animals of Africa, and even information about a migration that once was even greater than that of the African wildebeests – the American bison. When that population was wiped out, it left a wave of devastation that would also happen if the wildebeests had to stop migrating. The migration itself has a huge effect on the lands and other animals of Africa, and the reader comes to better understand those interactions.

This book is for readers around middle school age. They have to have a long attention span to handle all that text. And they need to be able to handle plenty of information about animals mating and wildebeests rutting. On the very first page, we learn that a lion has tiny barbs on his penis, and lion sex usually ends with a swat and a snarl from the lioness. This is in the context of saying that wildebeests are far more interesting to watch than lions, even if they aren’t nearly as popular for tourists.

For a kid who sticks it out, there’s a very good chance they could end up fascinated by Africa and its wildlife. I learned so much I didn’t know I didn’t know by reading this book packed full of beautiful photographs and information about the animals and environment of Africa.

Review of Overview: A New Way of Seeing Earth, by Benjamin Grant with Sandra Markle

Overview

A New Way of Seeing Earth

Young Explorer’s Edition

by Benjamin Grant
with Sandra Markle

Crown Books for Young Readers, 2019. 150 pages.
Starred Review
Review written 02/20/2020, from a library book

This book reminds me of The Earth from Above, by Yann Arthus-Bertrand, which I read and reviewed back in 2004. This is the same idea: photos of earth taken from above. But in the previous book, I believe the photos were taken by airplane. These are taken by satellite – but a satellite that can zoom in or out and still get detailed shots.

This book is packaged for children, with a text upper elementary kids can understand. The focus is the photos, so the text isn’t long, but does give some food for thought.

This book was revised by children’s nonfiction author Sandra Markle from a longer book for adults called Overview, and that book was based on an Instagram page showing satellite pictures.

There’s a foreword by retired astronaut Scott Kelly, where he explains how it can affect you to look at Earth from space:

From space, Earth looks like a peaceful place, without political borders. From orbit, astronauts get the sense that this is how Earth was meant to be viewed. This vantage point gives you a sense of oneness, an awareness that we are all part of the same humanity. Many people call this the Overview Effect, which is where this book gets its name. When astronauts experience the Overview Effect, we feel a greater connection to Earth, its people, and the environment that changes us forever.

The pictures in this book are stunning and amazing. Many of them are beautiful. With both manmade beauty and natural beauty. Many are disturbing – particularly ones of bright red polluted bodies of water. But this is a book you’ll enjoy looking at over and over again.

#4 General Children’s Nonfiction

I checked out this book thinking it would work well for booktalking in the schools. I was absolutely right, but now that schools are closed I’m going to have to wait another year to do it. So let me tell you about it.

I never dreamed a book about moles could be so entertaining! This author uses a conversational tone and really emphasizes the Wow factor of many strange characteristics of moles. One way she does this is by describing nine mole superpowers: Astonishing Architect of Dirt, Indefatigable Paws of Power, Double-Thumb-Digging Dominance, Arms of Hercules, Super-Squidgibility, Early Whisker Warning System, Headless Hoarding, Saliva of Death (Maybe?), and Blood of the Gods.

She describes moles in ways you can understand, such as shaped like a potato. And gives scientific terms more vivid names. The prepollex is given the name Weird Fake Thumb, or WFT for short. Scientists say that moles’ blood has high oxygen affinity. This author says they have the Blood of the Gods.

Here’s an example of the writing style in this book, taken from the beginning, after she’s explained that moles are shaped like a potato:

Now, potato-shapeliness is definitely too dowdy to be a superpower. But believe it or not, it’s a MOLE’S SECRET WEAPON.

Let me explain.

Scientists say moles and potatoes have cylindrical bodies. Cylindrical is a fancy way of saying “shaped like a tube.” But if you look at a potato, you’ll notice it is not shaped like a tube so much as shaped to fit inside a tube. And that is the important thing about potato-shapeliness – it helps moles fit in tubes. A giraffe would not fit in a tube. Neither would a poodle, nor a chicken, nor any other animal with long legs and a long, bendy neck. Big floppy ears would also not be good in a tube. Take it from me, if you’re going to live in a tube, it’s best to be shaped like a potato.

Of course, moles don’t live in any sort of tube. They live in underground tunnels. And not just any underground tunnel. Moles are MASTERMINDS OF UNDERGROUND EXCAVATION! They are ASTONISHING ARCHITECTS OF DIRT! They are TUNNELING TORPEDOES! Which brings me to ROSALIE’S FIRST SUPERPOWER.

The cartoon illustrations also fit the tone perfectly.

So there you have it – I now know about the wonders of moles. I read an entire book about moles and enjoyed every moment of it. Who knew science could be so much fun?

#6 General Nonfiction

I finally read this book by listening to it on an eaudiobook. I had read the Young Readers’ Edition, Can You Hear the Trees Talking?, which includes the general ideas presented here, along with glorious full-color photographs.

On audiobook, the narrator’s pleasant voice and British accent makes for a nice listening experience, though I don’t absorb facts as well by listening as I do by seeing. Still, this was just as fascinating as the children’s version, with many more interesting details.

I learned more information about how the forest is connected through fungi in the soil. Trees can even feed other trees that are in distress through the fungi. I learned about how trees communicate through scent – by producing chemicals – and through the fungi. I learned that trees can learn and how “mother” trees train their children to grow slowly at first, and how that helps them to live longer lives. I learned how the forest is interconnected and it’s actually a disservice to trees to clear out old rotting stumps. I also learned that they have discovered stumps cut down centuries before that are still alive because their neighbors feed them. And many other fascinating details like that.

This did make me look at forests with new eyes. Trees are living things and although their ways of communicating and learning and adapting are completely different from ours, scientists are learning that they do these things. And Peter Wohlleben is particularly skilled at passing on that knowledge.

He also has some theories about how walking in the forest makes us feel good. It turns out that’s more true in a healthy forest. It made me want to run out and walk in a forest right away.

Now that I’ve started, I’m going to read more of his books.

Here’s what it says on the page at the front of this book:

Let’s Make Some Noise

Learning the sounds animals make is an essential part of language learning. Spending hours and hours pretending you’re a chicken or a dog is not only great fun, it’s educational, too. If you grew up speaking English, you probably already know your woofs and meows from your clucks and quacks – but how does the rest of the world describe sounds?

[This next part has cartoon animals.]
In Japanese, cats don’t go MEOW. “NYAN!”
In German, pigs don’t go OINK. “GRUNZ!”
In Hindi, frogs don’t go RIBBIT. “TARR!”

There’s a whole world of words for all the sounds you know and love! (And even some words for sounds that don’t show up in English.)

The words that imitate sounds are known as “onomatopoeia.” These words are a wonderfully strange and interesting part of language. After all, we hear the same sounds, but we interpret and write them differently in different languages.

If you sing “Old McDonald Had a Farm” in French, your farmyard ducks go “coin coin” instead of “quack quack,” and in Russian they go “krya krya.” From the sound of a speeding car, to the sound a dog makes, to the sound of rain, there are almost as many words for these sounds as there are languages!

The format of this book is chapters of types of sounds with spreads looking at one certain type of sound in multiple languages. It’s in graphic novel format, so we see the sounds in speech bubbles coming from cartoon animals or characters or things. The chapters are “Animal Noises,” “On the Farm,” “In the Zoo,” “Loud Noises,” “Natural Noises,” “Noisy Machines,” “Sounds of the Human Body,” and “Sounds of Emotion.”

We learn fascinating things, such as “Kusukusu” being the Japanese word for “Ha Ha” and “Tagaktak” being the Filipino word for “Splat” and “Vzheeh” being how Russians say “Zoom.” It’s all mind-expanding to think about the many different languages, but also mind-expanding to realize how many different words we have in our own language for sounds.

This isn’t a book that fits neatly into a curriculum anywhere. You couldn’t use it to learn a language. But it’s super fun to read and to think about. This is a book that could easily capture a child’s imagination. I know it captured mine.

The one little thing that I wish it had is a pronunciation guide, since I know in some languages, English letters don’t make the same sounds. Though perhaps they left that out because once they started, it would have gotten tricky with so many languages used. This keeps it light and fun, but still informative.

Create Your Own Secret Language

Invent Codes, Ciphers, Hidden Messages, and More

by David J. Peterson
illustrations by Ryan Goldsberry

Odd Dot, 2020. 144 pages.
Review written November 28, 2020, from a library book
Starred Review

I’ve always liked books about codes, ciphers, and cryptography. In fact, I made a video series for kids this summer while the library was closed about using mathematical concepts to make ciphers.

This book shows us many kinds of codes and ciphers (though not the same ones I used), but takes things a few steps further, showing kids not only how to encode English, but even how to create their own secret language.

It starts as many books on codes do, with letter substitution codes and historical ciphers. But this one goes further by telling you how to design your own glyphs and a whole new writing system. Why should you be confined to the English alphabet?

This all culminates in a section at the back on designing an entire language. It begins by looking at the sounds you may want to use in your language and how they’ll be put together in syllables and word forms. Then it goes on to look at different parts of speech and the ways they vary in English. For example, nouns have singular and plural forms. How do you want your language to do that? English verbs have different forms for singular and plural and ways to show different tenses. Then there are adjectives, adverbs, and pronouns. And you might even want to make related nouns with similar root forms.

That sounds complicated – but this author makes it seem simple, with lots of worksheet space in the book to play with your ideas. (Buy a copy so you aren’t tempted to write in the library book!)

It turns out the author has done this himself, having invented languages for various films and series, including Game of Thrones. Who better to play with these ideas than kids? And they’re going to learn a lot about how language works while they’re at it.

As soon as I read this book, I knew which book I hope wins the 2021 Caldecott Medal.

When I was a child, I had a book from Disney publications that included a chapter on bees with lots of close-up photos. I hated that part of the book and didn’t even want to turn the pages for fear I’d touch the pictures of the bees.

I must have outgrown my squeamishness, because this book is full of oversize close-up paintings of bees, and I think the book is beautiful. Perhaps it’s the fact that they’re paintings instead of photos – Eric Rohmann has made the bee featured here look positively plush and cuddly, while still being completely scientifically accurate.

I learned so much I didn’t know about bees when reading this book. I knew that worker bees have jobs in the hive. But I didn’t know that the same bee gets different jobs as it ages. This book highlights the different jobs a bee goes through. After the bee has emerged from a cell in the honeycomb, here are a couple of early pages:

Crawling to a cell packed with sticky, rich pollen,
Apis eats.
And eats.
And eats some more.
Her wings dry. Her color darkens to a warm yellow orange. Her muscles grow strong.

Strong enough for flying?

Not yet . . . cleaning comes first.
Apis’s first job is to tidy the hive’s nursery.
She hauls away leftover bits,
carts off old wax caps,
leaves each cell ready for a new bee egg.
When she turns three days old, special glands behind her face swell and expand.
Soon she is ready for her next job.

Flying?

No, Apis doesn’t fly yet. First, we see her do the jobs of nursing, queen tending, comb building, food handling, and guarding.

When she finally flies, on the twenty-fifth day of her life, Apis gets a beautiful fold-out section in the middle of the book featuring a wide-open sky.

We do of course learn how she gathers nectar and carries pollen and dances to tell other bees about her finds.

The book goes all the way to our heroine’s death and then comes full circle with a new honeybee coming out of its cell in the hive.

This is another book for which I can’t do the striking pictures justice. I didn’t even think I liked to read books about bees, but I was captivated by this beautiful book. The writing, too, is wonderful. With each job, the writer builds suspense, asking if Apis is finally ready to fly.

Go check this out and see for yourself!
