Electricity provides the power for many things in our lives--computers, ovens, TVs, hair dryers, and much more. Learn about electricity and how it flows through a circuit to power things. Use your new knowledge about electricity to build a potato battery to power a light bulb.

If you want to look good, perform at your peak and be in tip-top shape, you must choose smart fuel for your body, not the processed “food” found on the shelves of every supermarket. Many have turned to Paleo and a low-carb way of life to avoid the effects of these food impostors we were never designed to eat. Low-carb diets, however, can leave you feeling as though you don't have enough gas in the tank. Low carbs need to be smart carbs. Lucky for us, nature has given us the nutritious, delicious sweet potato. This super food gives all the benefits of other high energy foods with more nutrition and without spiking blood sugar. Plus, this humble tuber tastes great and is easily incorporated into your diet in seriously good ways. Sweet Potato Power gives you the tools to run your own tests to determine the diet rules that work specifically for you and your unique biology. Through self experimentation, you can cut through diet mumbo jumbo, and let science and your numbers speak for themselves to answer questions such as: • How many carbs should I eat to make me look, feel and perform at my best? • What foods spike my blood sugar the most and make me fat? • How do I eliminate craving? • How can I avoid mental fogs and post-lunch energy slumps? • How can I optimize my carbs with my athletic pursuits?How can I get fit without getting fat?What exercise is best for my body? • How can my kids become the most delightful version of themselves? • How can my doctor be a well-care provider instead of a sick-care provider? Understanding a bit of science and incorporating new tools in your arsenal will make you an active participant in your health. Applying what you learn brings you closer to the ideal version of you. All of this and easy sweet potato recipes so you can incorporate this power food into your everyday life—making Sweet Potato Power a force to be reckoned with!

Developments in potato chemistry, including identification and use of the functional components of potatoes, genetic improvements and modifications that increase their suitability for food and non-food applications, the use of starch chemistry in non-food industry and methods of sensory and objective measurement have led to new and important uses for this crop. Advances in Potato Chemistry and Technology presents the most current information available in one convenient resource.The expert coverage includes details on findings related to potato composition, new methods of quality determination of potato tubers, genetic and agronomic improvements, use of specific potato cultivars and their starches, flours for specific food and non-food applications, and quality measurement methods for potato products. - Covers potato chemistry in detail, providing key understanding of the role of chemical compositions on emerging uses for specific food and non-food applications - Presents coverage of developing areas, related to potato production and processing including genetic modification of potatoes, laboratory and industry scale sophistication, and modern quality measurement techniques to help producers identify appropriate varieties based on anticipated use - Explores novel application uses of potatoes and potato by-products to help producers identify potential areas for development of potato variety and structure

Remember: Science fair projects are due...NOW! It’s no secret that kids sometimes put off doing their assignments, especially if they get busy or don’t know where to begin. But with this compilation at hand, their science fair problems are over, because it’s full of super-quick ideas sure to wow the crowd and the judges. All the experiments use common, easy to find materials, and there’s valuable advice on creating an appealing presentation and writing an accompanying report. Construct a "Juice Rocket”; grow crystals along a piece of string; build a biosphere; and mummify an orange. And here’s one for the birds: an experiment to determine if our avian friends prefer one type of food over another. Every project is smart and fun!

See science in action through these simple, fun electricity experiments. From making a simple motor to a homemade flashlight, step-by-step instructions illustrate experiments and the the science behind them.

Prior to 1862, when the Department of Agriculture was established, the report on agriculture was prepared and published by the Commissioner of Patents, and forms volume or part of volume, of his annual reports, the first being that of 1840.
