Who are we, really? We share traits with our parents, but our genetic makeup is unique. Each one of us is a one-and-only creation. Through colorful photos, diagrams, and text, you can learn about genetics. See how the simple pea plant taught us the rules of inheritance. Find out how our genetic code is unlocking the mystery of where we came from and our connections with all living things.
All life starts with a set of instructions that can turn basic cells into hearts, tails, flower petals, or toenails. DNA is the amazing code of life that is found in every organism. Through colorful photos, diagrams, and text, you can learn how DNA is passed from cell to cell, controlling growth and change in all living things. Find out how we can use the properties of DNA to save endangered animals and even to catch criminals!
From insects to elephants, every living thing on this planet is made up of cells, the tiny building blocks of plant and animal life. Each cell is alive-and each has work to do! What do cells look like? How do millions and billions of cells work together to form one plant, one animal, or one human being? Guided by colorful photos, diagrams, and text, you can take a closer look at the amazing world of cell science-and see what's next.
Why do people migrate to and settle in the places they do? Fascinating examples from history help explain the determining factors of migration. Readers will fascinated to read about the settling the Nile in ancient Egypt; the Industrial Revolution in Britain; the opening up of the American West; the Gold Rush; and the colonization of Australia.
This engaging and informative book explores the science of simple machines and how it relates to the exciting field of mechanical engineering. Readers will learn how mechanical engineers design and innovate machines we use every day. Readers then apply the engineering design process to tackle a design challenge of their own.
Civil engineering is one of the oldest engineering fields. Civil engineers are involved in the design and construction of various structures, including high-rise buildings, sports stadiums, canals, dams, and bridges. This book gives readers a up-close look at the technology used to build various structures around the world, including the ancient pyramids, the Eiffel Tower, the Golden Gate Bridge, and modern skyscrapers. Readers learn about the design process and tools used by civil engineers and are guided through a design challenge to create their own stable structures.
Aerospace engineers work with different kinds of aircraft, from gliders to space shuttles. This book introduces readers to this profession. Readers learn how engineers use the principles of flight to design and innovate airplanes, rockets, and more. Clearly written text outlines the steps in the engineering design process and guides readers through the steps to create their own flying machines.
The plant kingdom contains more than 250,000 species. This colorful book describes the main groups of plants, including mosses, ferns, conifers, and flowering plants. Special sections highlight the role of plants in the environmentas producers in the food chain and producers of the worlds oxygenand their role in climate and the water cycle.
This interesting book features an examination of the four major groups of fungi: yeasts, toadstools, chytrids, and bread molds. Special sections explore varieties that feed on dead and decaying matter, parasites, and species that form relationships with other species. Case histories involving fungi include penicillin and the fight against disease, and genetically modified (GM) products in food technology.
This book examines bacteria that are found in virtually every environmentincluding those that are characterized by extreme heat, cold, and depthand, of course, bacteria that are found inside our bodies. Case studies examine the development of new vaccines against bacterial diseases and the use of bacteria to help fight pollution.
Some Archaea thrive in extreme places such as in thermal pools, hot vents at the bottom of the sea, extremely salty water, and even in underground oil reserves. This book examines the diverse Archaea kingdom and the division of these organisms by their unusual biology into three main groups. It also explains why little in general is known about them, and why further classification of Archaea is so difficult.
How in the world do you classify the more than one million species in the animal kingdom? This fact-packed book divides animals into the major phyla, classes, and critical features. Fascinating case histories examine the discovery of new mammal species, the need to conserve endangered species, and using natural predators to control populations and preserve species and their environments.
The Earth system comprises diverse components that interact in complex ways. Earth science includes the study of the atmosphere, hydrosphere, oceans, and biosphere, as well as the solid earth. The reproducible activity pages supplement earth science textbooks with stand-alone or coordinate one-page lessons. Sample activities include: Cenozoic Era, Comparing Types of Rocks, Eclipses, Formation of Coal, Glacial Landforms, Global Heat Budget, How Minerals Form, Igneous Rocks, Waves, and More!
