It is hot and dry in California’s desert. Under a tent, scientists dig in the sand. They are looking for mammoths, giant elephant-like creatures. But the scientists are not looking for living mammoths. Mammoths died out about 4,000 years ago. These scientists are paleontologists. They study past life on Earth. They learn by looking at fossils, the hardened tracks or remains of animals. Paleontologists have studied fossils of mammoths found all over the world.
How the Earth Works - 60 Fun Activities for Exploring Volcanoes, Fossils, Earthquakes, and More
Earth science comes alive for children 6 to 9 through 60 engrossing games, activities, and experiments. Kids core sample a filled cupcake and discover plate tectonics by floating graham cracker continents on a molten mantle of molasses. They learn how heat changes rocks by seeing how separate ingredients disappear when they bake Rice Krispie Treats. More activities show what causes earthquakes and what kinds of buildings resist their force. Growing sugar and salt crystals, fossilizing plastic insects, and modeling a variety of volcanoes add to the learning and the fun. Eight of the activities are tasty as well as informative.
Here is a spectacular guide to the amazing world beneath our feet. Color photographs of rocks, fossils, minerals, precious metals, crystals, jewels and gemstones give the reader a unique insight into the evolution and composition of the Earth. See rocks that have come from outer space, stalactites as old as dinosaurs, and nuggets of gold, silver and platinum. Learn what the Earth is made of, how its rocks were formed, and how diamonds and precious stones are cut and made into jewelry. Discover how prehistoric animals are preserved today as fossils, how volcanoes work, how minerals and metals are mined and how pebbles on the seashore are worn down into sand, and much, much more.
Excavating Victorians examines nineteenth-century Britain's reaction to the revelations about time and natural history provided by the new sciences of geology and archaeology. The Victorians faced one of the greatest paradigm shifts in history: the bottom dropped out of time, and they had to reinvent their relationship to the earth and to time and history. These new sciences took the Victorians by storm, inundating them with fossils, skeletal remains, and potsherds-artifacts, or traces, that served at once as relics from the past, objects in the present, and markers of time's passage.
How do fossils form? Where were some of the most unique fossils discovered? How have fossils helped paleontologists learn about dinosaurs? Readers will find the answers to these questions and more in Fossils. Students can discover the fascinating planet we live on as they explore the Earth Science Series. Packed with informative charts, diagrams, maps, and sidebars, this series facilitates learning and encourages higher-level thinking. Earth Science is an informative and visually appealing series that will inspire a new understanding of geology and our world.
