Gizmos & Gadgets: Creating Science Contraptions That Work (& Knowing Why) (Williamson Kids Can Books)by Jill Frankel Hauser
Synopses & Reviews
Kids will have a blast investigating the hows and whys of motion, friction, gravity, balance, spinning, and energy by constructing awesome working contraptions.
Find out how parachutes, catapults, and whirligigs work, why cars need friction (so the brakes work!), and how a hovercraft "hovers" — and more!
Gear up to discover science by constructing weird, wacky contraptions. With this guide, children can start building, questioning, creating, and inventing--all the while learning fun physics principles and good science practices. 150+ illustrations.
The fun of physics principles is revealed as kids invent over 75 safe science contraptions. Fly wheels, gears, pulleys, and spin lifters become Action Reaction Rockets, Inertia Zoom Balls, Marshmallow Catapults, and more. 150+ illus.
