"Shows readers how to turn rubber bands, paper clips, straws, plastic bottles, and index cards into amazing, gravity-defying flyers. 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"--Provided by publisher.

There's no need for expensive, high-tech lab equipment to conduct chemistry experiments -- you probably have all you need in your home junk drawer. Turn three pennies and two galvanized washers into a simple battery. Crush a soda can using atmospheric pressure. Convert an LED flashlight into a simple electrolyte tester. Split liquid water into two unique gasses, or use cornstarch to create a gooey, mysterious, non-Newtonian fluid. And model radioactive...

"Biology is the study of life, and all the wonderful, squishy, messy parts that living things are made of. And children love messy science, especially hands-on experimentation! Junk Drawer Biology will 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. Aspiring doctors can build a model of human lungs with balloons and a soda bottle, and a homemade stethoscope...

Examines some fun science experiments. Crash, boom, bang: destroy! There's nothing children love more than the satisfying smashing and bashing of things being demolished. They always do it for sheer amusement; now they can do it in the name of science. And they'll enjoy it so much that they won't even think they're learning physics as they're wrecking stuff. Just imagine the expression on kids' faces as they watch a microwaved marshmallow grow bigger...and...
