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 “car” 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?

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.
