There's no need for expensive, high-tech materials to test your engineering skills-you probably have all you need in your home junk drawer. Each hands-on project in this book will challenge you to come up with a unique solution to a specific design problem. Construct a Pasta Bridge strong enough to support a heavy load, using only dry linguini and glue. Build a Marble Roller Coaster from recycled cardboard tubes, in which the marble "e;car"e; jumps a track to land safely at its final destination. Or design an Egg Catch device to safely capture a free-falling egg. Test yourself or use them for friendly competitions-who can come up with the best solution?These 25 open-ended design challenges can be performed for just pennies . . . or less. Each project has a suggested materials list, step-by-step instructions with illustrations for one possible solution, and suggestions on how to adapt each challenge for different ages and skill levels. Educators and parents will find this title a handy resource to teach children problem-solving skills and applied physics, all while having a lot of fun.

Kids of all ages can use recycled and repurposed household items to complete exciting and green ecology experimentsJunk Drawer Ecology is a hands-on guide to saving the planet. Fun, free science activities help kids of all ages learn about the science of our planet's ecology. The environment is changing every day, and we can help slow that change. Using free or low-cost things children already have around their homes, these activities are perfect to stimulate young brains. Readers will learn about the importance of the polar regions without leaving their communities, about new ways to cut our dependence on fossil fuels, about all forms of pollution, and how they can make a difference.Junk Drawer Ecology will give inquisitive kids many hours of fun and help them learn at the same time.

Calling all future Amelia Earharts and Chuck Yeagers--there's more than one way to get off the ground. Author and physics teacher Bobby Mercer will show readers 35 easy-to-build and fun-to-fly contraptions that can be used indoors or out. Better still, each of these rockets, gliders, boomerangs, launchers, and helicopters are constructed for little or no cost using recycled materials. The Flying Machine Book will show readers how to turn rubber bands, paper clips, straws, plastic bottles, and index cards into amazing, gravity-defying flyers. Learn how to turn a drinking straw, rubber band, and index card into a Straw Rocket, or convert a paper towel tube into a Grape Bazooka. Empty water bottles can be transformed into Plastic Zippers and Bottle Rockets, and ordinary paper can be cut and folded to make a Fingerrangs--a small boomerang--or a Maple Key Helicopter. Each project contains a material list and detailed step-by-step instructions with photos. Mercer also includes explanations of the science behind each flyer, including concepts such as lift, thrust, and drag, the Bernoulli effect, and more. Readers can use this information to modify and improve their flyers, or explain to their teachers why throwing a paper airplane is a mini science lesson. Bobby Mercer has been sharing the fun of free flight for over two decades as a high school physics teacher. He is the author of several books and lives with his family outside of Asheville, North Carolina.

Algebra as a hands-on subject? With this helpful resource, you can simplify equations using pennies and nickels, use aluminum foil to multiply polynomials (the FOIL method), create coordinate graphs with candy, examine exponential decay functions with a bouncy ball, and much more. Junk Drawer Algebra proves that you don't need high-tech equipment to comprehend math concepts-just what you can find around the house or in your recycling bin. Each of this book's fifty creative algebra projects includes a materials list and detailed, step-by-step instructions with illustrations. The projects also include ideas on how to modify the lessons for different age and skill levels, allowing anyone teaching children to use this to excite students. Educators and parents will find this title a handy guide to teach problem-solving skills and algebraic equations, all while having a lot of fun.

For many children, geometry is best understood as a hands-on subject. What better way to explore concepts such as area, perimeter, and volume than actually measuring area, perimeter, and volume? With this handy resource, children will build polygons out of pipe cleaners and flexible drinking straws, explore Mobius strips made from index cards, and model the Pythagorean Theorem using cheese crackers. These activities and more can be found in Junk Drawer Geometry , which demonstrates that you don't need high-tech equipment to comprehend math conceptsjust what you can find around the house or in your recycling bin. Educator Bobby Mercer provides readers with 50 creative geometry project ideas for engaged learning. Each activity includes a materials list and detailed, step-by-step, instructions with illustrations. The projects introduced here include ideas on how to modify the lessons for different age groups, allowing anyone teaching children to use this to excite any classroom. Educators and parents will find this title a handy resource to teach children problem-solving skills and applied geometry, all while having a lot of fun.

A children's instructional book on how to use readily available materials to turn the house into a science lab Physics teacher Bobby Mercer provides readers with more than 50 great hands-on experiments that can be performed for just pennies, or less. Turn a plastic cup into a pinhole camera using waxed paper, a rubber band, and a thumbtack. Build a swinging wave machine using a series of washers suspended on strings from a yardstick. Or construct your own planetarium from an empty potato chip canister, construction paper, scissors, and a pin. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated. Junk Drawer Physics also includes sidebars of fascinating physics facts, such as did you know the Eiffel Tower is six inches taller in summer than in winter because its steel structure expands in the heat? Educators and parents will find this title a handy resource to teach children about physics topics that include magnetism, electricity, force, motion, light, energy, sound, and more, and have fun at the same time.

A children's instructional book on how to use readily available materials to turn the house into a science lab Science teacher Bobby Mercer provides readers with more than 50 great hands-on experiments that can be performed for just pennies, or less. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated. From turning three pennies and two galvanized washers into a simple battery to crushing a soda can using atmospheric pressure, the experiments in this book call for materials that are recycled or repurposed—crayons, plastic drink bottles, balloons, ice cubes, and other basic items found around the house. Junk Drawer Chemistry also includes sidebars of fascinating chemistry facts. Educators and parents will find this title a handy resource to teach children about chemistry topics that include atoms, compounds, solutions, mixtures, reactions, thermodynamics, acids and bases, and more, while having fun at the same time.
