"This book contains sixty activities, many of which can be used by teachers of all grades. Teachers and parents with little or no background in science or chemistry can understand and conduct these activities. Students can do them, too, if supervision is provided. The catchy title of each activity and the 'magic show' approach are meant to capture attention, arouse curiosity, and dispel chemophobia"--Preface, v

The most comprehensive state project of its kind, the Dictionary provides information on some 4,000 notable North Carolinians whose accomplishments and occasional misdeeds span four centuries. Much of the bibliographic information found in the six volumes has been compiled for the first time. All of the persons included are deceased. They are native North Carolinians, no matter where they made the contributions for which they are noted, or non-natives whose contributions were made in North Carolina.
How do soaps and detergents clean? Why do metals conduct electricity? How does burning fossil fuel contribute to global warming? The answers to these questions are found by examining the properties and behaviors of atoms and molecules. Insightful explanations and hands-on science activities simplify complicated chemistry principles into pieces of information that are more easily grasped. Sidebars include discussions on animals that can live thirty years without water, the Maillard reaction responsible for the taste and texture of french fries, the increase of carbon dioxide in the atmosphere, and how tires provide a cushion of air to smooth our rides. This book allows students to appreciate that when it comes to understanding the world around us, tiny molecules can provide big explanations.
Focuses on Earth energy resources, such as renewable power from water, ocean energy, solar energy, wind energy, and biofuels, as well as non-renewable sources.
Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.
How does a city obtain water, gas, and electricity? Where do these services come from? How are they transported? The answer is infrastructure, or the inner, and sometimes invisible, workings of the city. Roads, railroads, bridges, telephone wires, and power lines are visible elements of the infrastructure; sewers, plumbing pipes, wires, tunnels, cables, and sometimes rails are usually buried underground or hidden behind walls. Engineering the City tells the fascinating story of infrastructure as it developed through history along with the growth of cities. Experiments, games, and construction diagrams show how these structures are built, how they work, and how they affect the environment of the city and the land outside it.
