A capitivating and beautifully photographed Scientists in the Field title about a man trying to discover the effects pesticides have on frogs and, in turn, on us.

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

Frog Scientist tells the story of a particular frog scientist, Tyrone Hayes, who began with an interst in frogs as a child, attended Harvard where he met his wife, and earned a doctorate at Berkely. This book outlines the scientific steps involved in the investigative process and shares personal bits of information about Tyrone, his students and his family. Incredible pictures of many frogs and toads. Of interest to those interested in the amphibians and the scientific process.

This is a very informative non-fiction book that portrays the studies of Dr. Tyrone Hayes. Growing up, he just loved frogs and science, which led him to Harvard University. Struggling at first, he eventually found his way into the amphibian lab and started to flourish. He started studying reasons why the American frogs were dying out and found that a particular chemical called atrazine was making male frogs produce eggs instead of sperm. It is because of his research that the frogs were saved. Students will enjoy this book, especially if they are like Dr. Hayes and likes amphibians. The book includes amazing color photos of different frog species.For the classroom, I would have students study the life cycle of a frog and make a poster demonstrating it. They will either draw pictures or find pictures online to use on the poster.

This book is about an African-American scientist named Tyrone Hayes. He studies amphibians and is currently trying to find out the effects of pesticides on amphibians, frogs in particular. He knows that pesticides have harmful effects on animals and wants to find out exactly what is killing some frog species. Dr. Hayes decides to conduct an experiment on juvenile leopard frogs. He contaminates some water with atrazine and the other group of frogs is not contaminated. He has noticed that some frogs are feminized, meaning the male frogs have produce both eggs and sperm. He hopes this experiment will clear up his confusion. However, after the experiment, the results are not what he expected. The frogs from the contaminated pond are feminized;however, the frogs from his experiment groups were not feminized. He feels the results are due to the fact that he could not determine the exact ages of the frogs used. This book also tells the story of Tyrone's childhood and how he made it through Harvard. This book discussed many important topics including experiments and various frog species. A teacher could use this book to teach students about experiments. When Tyrone conducts his experiment he talks about his hypothesis, control group, variables, etc. He uses terminology that students must be familiar with in order to understand experiments. Therefore, it is important for a teacher to discuss experiments with the class. This book provides a perfect opportunity for a teacher to conduct an experiment in the classroom to give students a hands-on learning experience. Another topic that is important is the effects of pesticides on animals. Today, so many farmers spray their crops with pesticides, and they have harmful effects on wildlife. Therefore, it is important that teachers discuss with their students how harmful these effects can be. Students need to be knowledgeable and pesticides and nature.This book provides a prime example of how pesticides can affect animals. Therefore, teachers could have students discuss other animals that have been affected by pesticides or other man-made materials.Overall, I enjoyed this book. I feel like it is great for grades 4-6. This book is nonfiction and talks about the effects of pesticides on frogs. This book is also interesting because it also tells the life story of the scientist conducting the experiment, Tyrone Hayes. This book also has beautiful pictures of numerous types of frogs. I feel like this book would be great to have in my classroom library and would be very beneficial when my class is discussing frogs, amphibians, or experiments. This book reminds me of other scientific nonfiction books; however, I found this book more interesting because it was not only about frogs. It also tells about the scientist's life and how he came to love amphibians and science.

I'm a girly kind of girl so books about bugs and slimy creatures and such really don't interest me too much. However books with pictures like the ones in this book are kind of hard to ignore!! They aren't even pictures technically, they are photos. This book is about a frog scientist named Dr. Tyrone Hayes and all his experiments and adventures in grave detail. This book would be a great book to show in the classroom to students when they learn about cold blooded animals or amphibians. Children of young ages could benefit from this book as well as well as children of all ages! I recommend this book for anyone interested in learning about frogs or anyone who wants to see them up close, in book form.

This book is very fascinating. It really shows you the beauty of frogs. Surprisingly, when I look at the pictures in this book the frogs actually looked pretty! I know I wouldn't say that if I saw them in my front yard but the pages of this book are just rich in color and very amazing. The author did a wonderful job of having bold writing and made it easy to understand the facts about the different types of frogs. The book is mainly about Dr. Tyrone and his students exploring different types of frogs. Great book!

Frogs are cool, and so are scientists. Put them together, as written in Turner's clear, reader-friendly prose, and you have a winner. Literally--this book has been winning awards, it's so well done. Follow a real scientist as he grows up to become a frog specialist. Learn why his experiments are planned the way they are, and what they tell us about the environment. This book is lavishly illustrated with photos. When I recommended Frog Scientist to another teacher for her homebound student, she took a whole stack for him to choose from, and this is what he picked.
