A pygmy shrew is small—it's among the littlest mammals! A ladybug is even smaller, but it hardly seems tiny when you compare it to a protozoa! And there are many things smaller still—so small that we can see them only with a microscope. Would you believe there are particles that are so tiny that we can't measure their exact size? Explore the huge world of the very small!

What's faster than a cheetah?—no animal on earth can run faster. But a peregrine falcon can swoop faster than a cheetah can run. And the falcon can't compare to an airplane, a rocket, or the speed of light. Lively text and watercolors will make children laugh while they learn all about speed.

Over the recent years, identity has become one of the most central theoretical concept and topics of scholarship in a number of disciplines, including science education. In this volume, leading science educators articulate in carefully prepared case studies their theoretical perspective on science, learning, and identity. More importantly, the authors of the chapters that in the different parts of the book engage each other in a collaboratively written chapter concerning some of the central issues that have arisen from their individual studies; and in particular they engage each other over the similarities and differences between their approaches. This book, which features detailed case studies of identity as both resource and outcomes of learners in a variety of settings, will be of interest to anyone concerned with learning science in and out-of schools. The book also caters for readers who have wondered about how identity mediates science learning and, simultaneously, how engagement in science-related tasks and activities mediates the emergence and development of identities. The general tenor of all chapters is a cultural-historical and sociocultural framework that is brought to issues of identity, thereby inherently transcending the individual person and linking identity to cultural possibilities.

The blue whale is the biggest creature on Earth. But a hollow Mount Everest could hold billions of whales! And though Mount Everest is enormous, it is pretty small compared to the Earth. This book is an innovative exploration of size and proportion.

You asked for it---now you've got it In a focus group at a recent NSTA convention, teachers of prekindergarten through second grade clamored for help. They do want easy-to-do science activities they can use for everyday teaching. But they don't want to be forced to adapt material meant for older children. So here's the solution. Start Young offers a wealth of simple educational activities designed to use right away with even the littlest scientists. The book includes a chapter of helpful background on the latest thinking about effective ways to introduce science in early childhood. But the bulk of the book is two dozen articles compiled from Science & Children, NSTA's award-winning journal for elementary school teachers
