The critically acclaimed Scientist in the Field book about how one boy’s interest in backyard science inspired a career in scientific discovery.

When Tyrone Hayes was growing up in South Carolina, he didn’t worry about pesticides. He just liked to collect frogs. Tyrone’s interest in science led him to Harvard University, and though he struggled at first, he found his calling in the research lab of an amphibian scientist.

Meanwhile, scientists discovered that all around the globe, frogs were dying. The decline has many causes, including habitat loss and disease. Tyrone discovered that the most commonly used pesticide in the United States, atrazine, may also play a role. Tyrone tested atrazine on frogs in his lab at Berkeley. He found that the chemical caused some of the male frogs to develop into bizarre half-male, half-female frogs. What was going on? That’s what Tyrone wants to find out.

What People are Saying About This

From the Publisher

"Hayes comes across as both a dedicated scientist and a regular person, willing to work hard in pursuit of his scientific work yet quick to laugh and joke with his family and the graduate students he mentors. The result is one of the most compelling portraits of a scientific career the series has produced. Sharp, vivid photographs alternate between portrayals of the scientists—at work in field and laboratory settings, as well as relaxing at lab picnics and at home—and the frogs they study. The abundant images of many different frog species allow readers to observe in detail each animal’s characteristics, including size, anatomy, and habitat."—Horn Book, starred review
  ". . . lively volume . . . Well organized and clearly written, the text goes into detail about the process of analyzing the chemical’s affects on the frogs, but pulls back from specifics to show how the experiment fits into the larger picture . . . Excellent color photos offer clear pictures of frogs and of this scientific team at work in the field and in the lab . . . Throughout the book, Turner portrays Hayes as both a colorful personality and a dedicated scientist: the final chapter opens with a discussion of his four ear piercings and concludes with an overview of his research. A vivid, realistic view of one scientist at work."—Booklist, starred review

". . . a nifty narrative that conveys science in action, offers some insight into environmental damage, and provides a vivid portrait of an energetic and charismatic (and hunky) young scientist who's clearly inspiring students to take an interest in the field. The visually appealing layout is thick with images of people, making it easy to envision the realities of biological work, and of frogs, from hopping to undergoing dissection . . . useful as an introduction to the creation and execution of an experiment, and it will therefore be invaluable in science classes."—The Bulletin of the Center for Children's Books, starred review

"Of the same sterling quality as Sy Montgomery's engaging The Tarantula Scientist (2004) or her exciting Quest for the Tree Kangaroo (2006, both Houghton), this new addition to a stellar series opens an upbeat window to the adult application of youthful enthusiasms."—School Library Journal, starred review

Having used this book in my classroom this semester for a large unit on frogs, I highly recommend this book. My middle school students loved it, and I am positive that high school students would also find it rather interesting. It is a great aid in a science classroom, especially with the topics of environmentalism and frogs. The book is great because it focuses on a scientist who has spent his life learning about frogs, and it explores the current research that the scientist is doing on the effects of a chemical, atrizine, on leopard frogs.

This book is part of the "Scientists in the Field" series, which profiles different scientists to introduce science careers to children. This is the second book in the series that I have read, and I have been very impressed so far.This book gives students a glimpse intot the life of Tyrone Hayes, a herpetologist at UC Berkley. This book introduces students to both lab and field work, hypothesis testing, and science. Instead of shying away from complex issues and the controversy surrounding science, the book confronts them head on in an easy to read and informative manner. The book also goes into Tyrone's personal life, telling of the struggles he had as a bright young African American during college, and touches on his unique personality. this book really breaks down the stereotype of the scientist in the lab coat. I am currently loaning this book to a friend of mine who has a child interested in herpetology, and I would recommend it to any young student interested in the natural sciences.

This is the story of Tyrone Hayes, a passionate frog scientist. Dr. Hayes was contracted by a chemical manufacturer to study the effects of the pesticide atrazine on frogs. When he found that only an infinitesimal amount of the chemical caused the feminization of frogs, the chemical manufacturer tried to block Dr. Hayes' research from being published. Dr. Hayes fought the company so that he could share his findings with the scientific community and after much perseverance, emerged triumphant. Dr. Hayes' family life and his career as a university professor are detailed as well as information about specific frog species and what is being done globally to save them. This book would be very informative in a middle or high school science classroom. Students could read about a challenges that scientists face when the funding they receive comes from private interests, one man's path to becoming a scientist, what it is like to do field research and work in a lab, and frog facts. The photographs are beautiful and illuminating.

The Frog Scientist brings children straight into the research lab. There are captivating pictures of frogs being dissected, and all types of situations with frogs. The whole book is very educational and detailed information. The book would be great to use before a science lesson that had to do with dissecting. I would definitely use this book in my classroom. I love the details and the quality of the pictures. The book is well organized and clearly written, the text goes into detail about the process of analyzing the chemical's affects on the frogs, but pulls back from specifics to show how the experiment fits into the larger picture. The book is basically a guide to dissecting a frog, with great illustration. bc3301
