Follow scientists as they scan the Alaskan wilderness for these magnificent creatures. It is springtime on the North Slope of Alas...ka, and the U.S. Geological Survey team?the polar bear biologists Kristin Simac and Mike Lockhart?is gearing up for polar bear capturing. During a capture, all information is collected on the sea ice. The scientists locate bears from a helicopter, tranquilize them, give them tattoo ID numbers and tags, and collect data such as height, weight, and body fat measurements and samples such as blood, hair, feces, and even teeth. All this information goes into a large database studied by scientists such as Drs. Steven Amstrup and George Durner, the former and current leaders of the Polar Bear Research Project. For more than forty years, scientists have been capturing bears in order to get information. What has this information been telling scientists about polar bears and global warming?

A lively text and captivating images tell the story of the ever-curious boy who grew up to make one of the most significant discov...eries of our time. From the time Charles Darwin was a boy, he was happiest when he was out alone collecting specimens (especially beetles). And despite his fathers efforts to turn young Darwin ? a poor student ? into a doctor or clergyman, the born naturalist jumped instead at the chance to sail around South America, observing and collecting flora and fauna all the way. In a clear, engaging narration, Kathryn Lasky takes readers along on Darwins journey, from his discovery of seashells on mountaintops that revealed geological changes to his observations of variations in plants and animals, suggesting that all living things are evolving over time. Matthew Truemans striking mixed-media illustrations include actual objects found in nature, enhancing this compelling look at the man behind the bold theory that would change the way we think about the world ? and ourselves.
