Praying Mantises

praying mantisesPraying Mantises: Hungry Insect Heroes (Insect World) by Sandra Markle

Finally, a book about praying mantises that doesn’t perpetuate the myth that female praying mantises always eat their mates. Sandra Markle writes in Praying Mantises: Hungry Insect Heroes, “Scientists report that mantises rarely do this in the wild.” It turns out that the myth was started when people kept praying mantises indoors to observe them. Female mantises require a lot of food to produce eggs and the people who fed them rarely supplied enough. The ravenous females ate anything presented to them at that point. When kept outside, the praying mantis often has enough to eat and her mate doesn’t become lunch.

Sandra Markle starts with a detailed look at the outside and the inside of a praying mantis. This is helpful for someone who has never looked closely at a praying mantis. Throughout the book are fabulous photographs and quick “mantis facts” that help capture a reader’s attention as he or she skims through. At the end, between “Digging Deeper” and the index, there are two activities. The first, strike time, relates to how extremely fast a praying mantis can grab its prey. The activity is easy to do and doesn’t require a mantis. The second is to observe a mantis up close in a jar for a day or two and then let it go. Just remember from above, it is hard to keep a praying mantis well fed.

We have had a praying mantis on the same plant for weeks now. Every morning we check to see that it is still there, and we’ve developed a fond feeling towards it. After reading this book we can now take our observations to another level.

Penguin Secrets Revealed

secret-of-the-puking-penguinsSecret of the Puking Penguins . . . and More! by Ana María Rodríguez

Secret of the Puking Penguins and the other books in the Animal Secrets Revealed! series are actually well kept secrets themselves. Hidden behind the blaring, attention-grabbing titles are serious books for kids interested in real science. Ana María Rodríguez interviews five actual scientists about their research and describes new and interesting discoveries that they have made.

In the first chapter, scientists Anthony Herrel and Jay Meyers investigate how chameleons’ incredible tongues work. The tongues are not only sticky, as many of us already knew, but also are physically shaped to act like a suction cup. As the activity at the end of the chapter demonstrates, the suction cup action works much better at grabbing prey than stickiness alone.

The second chapter is about sensory apparatus in alligators. It isn’t until the third chapter does the reader find out about the “puking penguins.” As anyone who lived through the penguin craze of a few years back knows, penguins regurgitate food to their chicks. Rodríguez discusses how three French physiologists are so fascinated by the king penguins’ ability to hold food in their stomachs for long periods that they decided to study it further. By taking samples, the scientists revealed the penguins produce numerous antimicrobial substances (antibiotics) in their stomach to help preserve the food, including one completely new substance that no one had discovered before! How cool is that?

The final two chapters are about research of cuckoos, a bird that lays its eggs in the nests of other birds, and about how peacock feathers create their iridescent colors. “Chapter Notes” at the end are numbered references from each chapter. This is a nice touch that parallels how literature would be cited in an actual scientific paper, getting budding scientists ready to produce the real thing.

Other than the author should have included a few more activities to reinforce learning (there is just one), this book is fascinating and informative for young readers interested in science. Now let’s get the secret out.

Bouncing Baby Spiders

Babies are always cute, but some people might have trouble with using the words cute and spider in the same sneakyspinning-baby-spiderssentence. Those readers may change their minds after picking up Sneaky, Spinning Baby Spiders by Sandra Markle. In this book Markle has combined spectacular photographs of baby and adult spiders with carefully crafted text. For example, the photograph on page five of a jumping spider flying through the air as it pounces is amazing.

The accompanying text is exactly the right balance of factual and lively to make it informative and fun to read. It must have been difficult not to slip into anthropomorphism when the subject is babies, but the author kept just the right tone. Markle writes “mother spider,” but not “mom.” She also uses feminine pronouns instead of the neutral “it.” Those touches draw the young reader in.

Although the author has done a great job with the text, I did find one inaccuracy. Whenever an author is not an expert on a topic and has to rely on others for photographs, a chance for errors creeps in. In this case, the spider identified on page 24 as a “slender sac spider,” genus Chiracanthium, is actually a giant crab spider, genus Olios. One the plus side, the photographs also represent spiders from throughout the world, instead of from only one area or continent as so often is the case.

At the end of the book, the map of where the spiders are found is a nice touch. I also like Markle’s paragraph about how she was inspired to write this book by finding a spider’s web intact after a severe storm. It is a warm, personal note that sets the tone for the entire book.

All in all, Sneaky, Spinning Baby Spider is a wonderful addition to any library.

Wonderful Windmills

Wind and windmills were “hot” topics at our house last week, and therefore I was pleased to find The Wind at Work: An Activity Guide to Windmills by Gretchen Woelfle. Even though it is an older book (1997), it virtually stands alone on the topic of wind power and windmills for children.

Wind at Work covers the history and social aspects of using wind as a power source in great detail. From the early Persian windmills, through the use of windmills to pump water in the American West, Gretchen Woefle has done her homework. She provides many fascinating historical tidbits, such as how the saying “rule of thumb” came about. Who knew that the official seal of New York City has a windmill on it because windmills were so critical to early New Yorkers? In the final chapter, titled “Fulfilling the Promise,” Woefle explores the future potential of wind turbines as a renewable energy source. Even if you had some inkling of about wind power, Woelfe really brings home how important windmills and wind turbines were to our past and are to our future.

The chapters in this book are well-researched and clearly written. The accompanying activities, however, are a bit of a disappointment. Rather than emphasizing and/or clarifying concepts from the text of the chapter where they are included, the activities often seem to fit awkwardly. For example, for the chapter on ancient wind machines, the activity is to make a weather vane and wind sock. I think those would have fit better with the chapter on “A Windmiller’s Life” where the author says that the windmillers were the village weathermen. The “A Windmiller’s Life” chapter contains an activity to draw a landscape. The examples shown are landscapes with windmills, but the activity doesn’t suggest to draw windmills or even try to incorporate the idea of wind, simply draw a landscape. Surprisingly, the book does not contain a single activity for making a pinwheel, model windmill or even a kite that moves by wind.

Weaknesses with the activities aside, Wind at Work brings deserved attention to an often-overlooked topic. For those interested in wind as a power source, in history and/or in some of the modern environmental issues concerning wind power, this book stands out from the rest like a proud windmill at the top of a hill.
