review 1: Consider this for a twist on a mystery assignment for nonfiction readers in grades 1-4. Great nonfiction pleasure reading, too. I love this sentence in the author's note: "Perhaps, one day, one of you will become the science detective who stops this [amphibian] killer." I love that this book takes budding readers/budding scientists seriously and gives them a little bit of guidance and inspiration for the future.
review 2: Why are the Golden Frogs of Panama disappearing? Let's research! Great junior nonfiction. The book's respectful to it's readers and well organized. I especially like that Markle includes the various theories considered by Karen Lips as she tried to figure out what was killing the frogs. Yes! Let's show scientific methods and processes and get ... moreaway from Eureka moments.The things you want in NF -- index, glossary, table of contents, author's note, how to help local frogs, a digging deep list of books and websites, and great photos -- are included. Interesting Things:- Golden frogs are considered good luck in Panama. Ancients used to bury golden statues of golden frogs with the dead for good luck in the afterlife. Even today they're considered lucky; people keep frog figures in their homes.-Amphibian means "living two lives" how great is that? (Should I have learned that in bio? Oh well.) -This one made me very sad, but here we go -- in the 1930s a South African scientist figured out a way to test for pregnancy by injecting African Clawed frogs with a woman's urine. If the frog either laid eggs or produced sperm in 12 hours, the woman was pregnant. Huge pregnancy testing centers used to keep thousands of frogs just for this purpose. This continued until the 1960s when other methods were developed. Jeeze, right? This is why humans don't deserve nice things. Even worse, after new methods were developed, they just released these frogs back into ponds. Yeah, humans are to blame for the frog dying -- the BD fungus killing frogs is either from this or from transporting bullfrogs around for eatingSorry to have made you sad. Book's a winner, though. less
