There's no need for expensive, high-tech lab equipment to perform biology experiments—you probably have all you need in your home junk drawer. Use balloons, drinking straws, and empty plastic bottles to construct working models of hearts and lungs. Investigate plant transpiration and photosynthesis with leaves and resealable bags. Build a candy DNA model using gumdrops, toothpicks, and licorice rope. Study capillary action in plant xylem using colored water and paper towels. Extract DNA from a banana using a simple chemical process. Or learn how to turn a smartphone into a photographic microscope. Here are 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—seed germination, osmosis, human senses and systems, chromosomes, mitosis and meiosis, and more.

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.

"Children love challenges, especially ones that involve hands-on experimentation and friendly competition. Can they build a bridge using only pasta and glue, one that a toy car can drive both under and over, and is sturdy enough to carry a considerable weight? Can they construct a "roller coaster" from recycled cardboard tubes in which the marble "car" jumps a track to land safely at its final destination? And can they create a device to safely catch a freefalling egg? These projects and more can be found in Junk Drawer Engineering, which demonstrates 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. At its heart, engineering is the application of science to solve a design problem. Science teacher Bobby Mercer provides readers with 25 open-ended design challenges for children of all ages. The projects can be modified to meet the skill levels of the children doing them, from elementary school kids to teenagers. Though each challenge includes suggested materials and one step-by-step, illustrated solution, children are encouraged to modify and improve on the basic design, and come up with new and more complicated design parameters. 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."--

Finalist for the 2015 AAAS / Subaru SB&F Excellence in Science Book exemplify outstanding and engaging science writing and illustration for young readers 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.

Lay a solid foundation of algebra proficiency with over 155 hands-on games and activities. To complement the natural process of learning, each activity builds on the previous one-- from concrete to pictorial to abstract. Dr. Thompson's unique three-step approach encourages students to first recognize patterns; then use diagrams, tables, and graphs to illustrate algebraic concepts; and finally, apply what they've learned through cooperative games, puzzles, problems, and activities using a graphic calculator and computer. You'll find each activity has complete teacher directions, lists of materials needed, and helpful examples for discussion, homework, and quizzes. Most activities include time-saving reproducible worksheets for use with individual students, small groups, or the entire class. This ready-to-use resource contains materials sufficient for a two-semester course in Algebra I and can be adapted for advanced students as well as students with dyslexia.
