Discusses the discovery and analysis of Archaeopteryx, a feathered dinosaur which may have been an ancestor of modern birds.

A mountain might be thousands of feet high, but it can still grow taller or shorter each year. This classic picture book explores how mountains are made-including how Mount Everest grew from a flat plain under an ocean to become 29,028 feet tall! Now rebranded with a new cover look, this book features simple activities and fascinating cross-sections of the earth's moving crust that clearly explain plate tectonics. Both text and artwork were vetted for accuracy by an expert in the field. This is a Level 2 Let's-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let's-Read-and-Find-Out Science is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.

Describes what fossils tell us about the physical characteristics and behavior of the large carnivorous Tyrannosaurus rex.

Animals find many kinds of shelter--bears live in caves, birds make nests, and ants tunnel under the ground. Snails and turtles and scallops and other crustaceous creatures don't need to make homes for themselves--nature has provided them with permanent homes. Zoehfeld describes how, for each animal, a shell is also the perfect protection from predators. Full color.

With colorful illustrations and engaging text, Phones Keep Us Connected is a fascinating look into the science, technology, and history of how phones work! Before telephones were invented, there was no way for you to sing "Happy Birthday" to your friend if she wasn't in the room with you. Now you can call anyone, anywhere in the world! How was the phone invented? How has it changed? Read and find out how a telephone can carry your voice across oceans, and how phones have changed the world. Featuring rich vocabulary bolded throughout the text, this book includes a glossary, a find out more section with an activity about building a string telephone, and an infographic about the history of the phone. Both the text and the artwork were vetted by Dr. Jerry D. Gibson, Professor of Electrical and Computer Engineering at University of California, Santa Barbara. This is a Level 2 Let's-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards.
