There's not need for expensive, high-tech lab equipment to perform physics experiments-you probably have all you need in your home junk drawer. 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. Use a cork, string, and water-filled plastic bottle to create a simple accelerometer. Or construct your own planetarium from an empty potato chip canister, construction paper, scissors, and a pin. Physics 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. Junk Drawer Physics also includes sidebars of fascinating physics facts: 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. Bobby Mercer has been a high school physics teacher for over two decades. He is the author of The Flying Machine Book, The Racecar Book, and Smash It! Crash It! Launch It! and lives with his family outside of Asheville, North Carolina.

Kids of all ages can use recycled and repurposed household items to complete exciting and green ecology experiments Junk 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.

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.

The projects in Junk Drawer Engineering demonstrate that you don't need high-tech equipment to make learning fun—just what you can find in your recycling bin and around the house. 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.

Fatal Forces is packed with the most amazing things about physics. Readers can find out how gravity can make them lose their heads, how they can get walloped by a lamppost, what can make fillings explode and how to reach terminal velocity. Eeek! Redesigned in a bold, funky new look for the next generation of HORRIBLE SCIENCE fans.

Geometry is a hands-on subject. What better way to explore the concepts of area, perimeter, and volume than actually measuring area, perimeter, and volume? With this helpful resource, you will build polygons out of pipe cleaners and flexible drinking straws, explore Mobius strips made from index cards, model the Pythagorean theorem using cheese crackers, and much more. Junk Drawer Geometry 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 50 creative geometry 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 applied geometry, all while having a lot of fun.

Why is there eight times more ice in Antarctica than in the Arctic? Why can you warm your hands by blowing gently, and cool your hands by blowing hard? Why would a pitcher scuff a baseball?Which weighs more-a pound of feathers or a pound of iron? Let science experts Christopher Jargodzki and Franklin Potter guide you through the curiosities of physics and you'll find the answers to these and hundreds of other quirky conundrums. You'll discover why sounds carry well over water (especially in the summer), how a mouse can be levitated in a magnetic field, why backspin is so important when shooting a basketball, and whether women are indeed as strong as men.
