Nonfiction Monday – The Dirt on Dirt

dirt1.jpg

As a child who lived in the sandbox, played in the mud, dug for worms and other creatures, I find books about this topic appealing. The back cover of the book begins with the words, “Muck around in the dirt!” Yes, this is the book for me! As for the rest of the world, how can anyone not like a book in which the table of contents opens with You and Dirt?

The Dirt on Dirt, by Paulette Bourgeois, is an interesting mix of information and activities (labeled FUN with Dirt). In the categories of You and Dirt, Dirt Matters, Buried!, Building with Dirt, and Dirt for Gardening, readers learn everything under the sun about dirt. Here are a few interesting facts.

Some animals, like elephants and pigs, wallow in mud to get rid of ticks and fleas. The dried mud then helps protect the animals from the heat of the sun.

There are more than a million dust mites in an average bed. They don’t eat dust, but rather flakes of skin. Since we shed skin flakes every minute, they never go hungry!

It can take from 100 to 10,000 years to make 2 cm (0.8 inches) of good topsoil from crushed rock.

In 1974, archaeologists uncovered 7,000 life-sized, clay soldiers while digging on a peasant’s farm near the city of Xi’an.

Earthworms turn rotting plants and animals into fertilizer and create spaces for air and water to flow through the soil.

Using vivid photographs and inviting illustrations, this text captures the imagination of readers. My seven year old son was enamored of the section on building with dirt, which looks closely at the world that lies beneath our feet and the animals who inhabit it. There is a wonderful true or false quiz that asks readers to test their knowledge of earthworms. The book also contains a glossary and extensive index.

Throughout the text readers are encouraged to try activities related to dirt science. They can experiment to see how soap and detergents work, bake a mud cake, make the world’s greatest dirt (from a homemade composting box), make a dirt shake to see what’s in dirt, learn about erosion, and more. On the Kids Can Press web site you can download a free activity.

I love just about about everything about this book, save for one thing. On the back cover of the book, is the sentence, “Earth, mud, grime, soil–whatever you call it, dirt is everywhere, even where you don’t expect it.” The scientist in me really bristles at the use of the word dirt, and I am disappointed that the word soil wasn’t used more often. I know this is picky, and that for some of you, this is simply a matter of semantics. However, I work very closely with teachers and kids in classrooms to define and study soil. Calling it dirt is akin to calling insects bugs.

Despite this one tiny complaint about the use of the word dirt instead of soil, I found this book to be extremely entertaining and informative. I highly recommend it.

Pi Day

Tomorrow, March 14th, is Pi Day. No, that’s not a typo. It is Pi day, as in 3.14159… you get the idea. The first Pi Day celebration was held at the San Francisco Exploratorium in 1988. That means tomorrow is the 20th anniversary of Pi Day.

What is pi anyway? I’m sure you remember it from math in some formula you memorized, but do you really know what it is? Pi represents the relationship between a circle's diameter (its width) and its circumference (the distance around the circle). Pi is always the same number, no matter the circle you use to compute it. In school we generally approximate pi to 3.14 in school, but professionals often use more decimal places and extend the number to 3.14159.

One activity I loved doing with students was to ask them to bring in a can and lid that would soon be recycled. I always brought in a few extras so that there would be a variety of sizes. Each student was given a lid and directed to measure the diameter and circumference. Students then divided the circumference by the diameter. We recorded the results on the overhead and discussed them. Most were amazed to find that the results were nearly the same, allowing for some margin of error in measurement. This is a quick and fun and provides a meaningful way to introduce the concept of pi.

What will you be doing for Pi Day? I hope you’ll be celebrating in some small way. Perhaps you could make a pi necklace. If you’re looking for ideas, visit the Exploratorium pi site. Since tomorrow will be poetry Friday, I just may write some pi poems.

Computation Podcast – One Grain of Rice: A Mathematical Folktale

rice.jpg

In this podcast, Laura Bradlee introduces listeners to the book One Grain of Rice: A Mathematical Folktale by Demi.

Introduction
The book I chose, One Grain of Rice, is another example of children's literature that exposes students to another culture. This classic mathematical folktale allows children a glimpse into another era of time through incredible illustrations that are full of exquisite detail and beauty that portray life in ancient India. This book would be an excellent way to begin a lesson about the concept of doubling and exploring large numbers. I hope that this book, along with my other book choices, will encourage children to become interested in different countries and cultures, opening their eyes to the great big wondrous world that we live in.

Outstanding Science Trade Books 2008

The NSTA list of Outstanding Science Trade Books for K-12 Students is out. The introduction to the list includes this excerpt about the books selected.

Each of these outstanding selections defies the traditional image of a child "curling up with a good book." Yes, they can be a source of great personal reading, encouraging students of all ages to stretch their skills and their imagination as they interact with the printed page. But these journeys of the scientific imagination seldom end with the final chapter. They have the capacity to draw the reader out from that cozy seat and into the natural world€”to observe, investigate, and continue the process of discovery that has characterized scientists from Aristotle to Hawking. The adventures begin here.

The list of books is below. Each title was assigned a reading level by the reviewers. These suggested levels are intended as guidelines and are not meant to limit the potential use of titles. Reading levels include: P = Primary (K–2); E = Elementary (3–5); I = Intermediate (6–8); A = Advanced (9–12). Finally, titles marked with a * are books that individual reviewers responded to with particular enthusiasm.

Archaeology, Anthropology, and Paleontology

Biography

Earth and Space Science

Environment and Ecology

Health and Science

Life Science

Physical Science

Technology and Engineering

Back in January I created my own list of outstanding science books published in 2007, and even used some of the NSTA categories. A few of my selections made this list. You should also recognize some of these titles as Cybils nominees and finalists.

Nonfiction Monday – On Matters Evolutionary

My Foundations of Education class has been studying religion in public education. Before we left for break, we spent time considering the evolution debate. This is a topic near and dear to my heart, and one in which I have a hard time buying the “teach all sides” argument, since my undergraduate degree was in biochemistry, and my masters and Ph.D in science education. That said, I do not believe the theory of evolution and my religious beliefs are mutually incompatible. One is faith, the other science, and I don’t believe my faith, or that of anyone else, belongs in a public school classroom.

For students who struggle with the notion of evolution, how it works, what it means, and other aspects, I like to share books that clearly present the science. I’m also interested in having them understand its historical roots. Here are two books I find to be valuable resources in discussing this topic.

lifeonearth.gif darwin.JPG

Life on Earth: The Story of Evolution by Steve Jenkins, explores the history of life on earth and Darwin’s revolutionary theory. It includes a timeline of life on earth in which the history of life is compressed into a 24 hour day so that readers can understand just how old our planet is, and for how long we humans have lived on it. The text begins:

The earth is more than 4 1/2 billion years old. For a long time, life couldn’t exist here. The ground was hot enough to melt rocks. There was not liquid water. Comets and asteroids frequently crashed into the surface, and volcanoes erupted constantly, filling the air with poisonous gases.

From here we learn about the first forms of life (microscopic bacteria) and the organisms that sprang up in their wake. Using his highly skilled cut/torn paper collage technique, we meet early sea life, plants, a T. Rex, other animals which are now extinct, and finally get a look at early man. The next page shows a small ground-level reptile, a larger reptile walking on its hind legs, a large bird on the ground, and lastly, a bird in flight. Beneath this sequence is the question, “Why have so many different forms of life development on earth?” From here, Jenkins launches into an introduction to Darwin and the theory of evolution. The text is packed with information, elucidated in meaningful ways by the illustrations. When describing survival of the fittest, 10 frogs appear on a page in which their strengths and weaknesses are described, and the mechanism by which they pass on their strongest traits is highlighted.

Overall, this is a gorgeous text that provides a strong introduction to the theory of evolution.

While Jenkins’ book provides a brief introduction to Darwin, The Tree of Life: A Book Depicting the Life of Charles Darwin: Naturalist, Geologist & Thinker by Peter Sís provides a more intimate look at the man. Who was Charles Darwin? We know him today as a naturalist, geologist, and the father of modern evolutionary biology. But did you know that Charles Darwin was a man who always regretted not learning how to draw? Even though he did not fancy himself an artist, he took “dense and vivid” written notes of all he observed. From these notes, Peter Sís has created a book of intricately drawn pen-and-ink and watercolor illustrations that depict Darwin's life as he developed his theories about the origins of life and natural selection. In what may be one of the best nonfiction introductions EVER, this book begins:

Charles Darwin opens his eyes for the first time! He has no idea that he will (a) start a revolution when he grows up, (b) sail around the world on a five-year voyage, (c) spend many years studying nature, and (d) write a book that will change the world. Luckily, he is unaware that (e) not everyone will see things his way, and that (f) he himself will have doubts about revealing his grand conclusions. This is his story.

If that introduction doesn’t grab you, then nothing will. From here readers will find tidbits from Darwin's extensive and legendary voyage on the Beagle, notes on Galapagos tortoises, bloodsucking benchuca bugs, Toxodon skeletons, and much more. Perhaps even more interesting is the way the text is set up. Beneath each 3/4 page illustration the text is divided into sections on public life, private life, and secret life. There is much to love about this biography, and much more to learn.

I highly recommend both of these books, particularly for middle school teachers tackling the topic of evolution.
