Might it be a result of climate change? Follow a team of scientists working to save these frogs and protect frog populations worldwide in this real-life science mystery.

A frog full of tadpoles? Impossible! Here, for the first time, is the strange but true story of Darwin's frog. After Charles Darwin discovered the frog in 1834, other researchers found that one of his specimens was packed full of tadpoles. Was the frog a cannibal, or perhaps a rare species that gave birth to live young instead of laying eggs? No. He was a male, holding the tadpoles safe in his vocal sac while they morphed into froglets. And the surprises didn't stop there. Author and frog scientist Marty Crump mines her firsthand experiences studying Darwin's frog to tell the fascinating story for young readers. Award-winning illustrators Steve Jenkins and Edel Rodriguez lend their art to a mix of beautiful photographs. Young readers will be enthralled by this story of real science, full of strange surprises.

Presents facts about the ongoing investigation into the decline of honey bees around the world from colony collapse disorder, as scientists look at the impact of such factors as pesticides, farmer transportation of bee hives, fungal infections, and climate change.

On July 28, 1996, two young men stumbled upon human bones in the shallow water along the shore of the Columbia River near Kennewick, Washington. Was this an unsolved murder? The remnants of some settler's or Native American's unmarked grave? What was the story behind this skeleton? Within weeks, scientific testing yielded astonishing news: the bones were more than 9,000 years old! The skeleton instantly escalated from interesting to extraordinary. He was an individual who could provide firsthand evidence about the arrival of humans in North America. The bones found scattered in the mud acquired a name: Kennewick Man. Authors Sally M. Walker and Douglas W. Owsley take you through the painstaking process of how scientists determined who Kennewick Man was and what his life was like. New research, never-before-seen photos of Kennewick Man's remains, and a lifelike facial reconstruction will introduce you to one of North America's earliest residents. But the story doesn't end there. Walker and Owsley also introduce you to a handful of other Paleoamerican skeletons, exploring their commonalities with Kennewick Man. Together, their voices form a chorus to tell the complex tale of how humans came to North America—if we will only listen.

The Classroom Go-To Guide for the Common Core is the first in a series of comprehensive tools to tap into the vast flow of recently published books for children and teens, offering recommendations of exemplary titles for use in the classroom. Currency meets authority, brought to you by the editors of the highly regarded review sources, School Library Journal and The Horn Book Magazine. This guide includes approximately 200 selections published since 2007 for grades 4-6 recommended by The Horn Book Magazine. The titles are grouped by subject and complemented by School Library Journal’s “Focus On” columns, which spotlight specific topics across the curriculum. Providing context for the guide, and suggestions on how to use these resources within a standards framework, is an introduction by Common Core experts Mary Ann Cappiello and Myra Zarnowski. These experts provide perspective on the key changes brought by the new standards, including suggestions on designing lessons and two samples plans. Following the introduction, you’ll find a wealth of books, by category. Each section includes a listing of the top titles with brief, explicit annotations, and key bibliographic data. “Focus On” articles are appended to appropriate categories to support in-depth curricular development. Each of these articles includes a topic overview and list of current and retrospective resources (including some fiction), and multimedia, that will enable educators to respond to Common Core State Standards call to work across formats.
