ScienceWiz(R) This children's classic, with its touch of whimsy, should be your child's FIRST electricity book . The Electricity kit includes a highly visual, full color, step-by-step, 40 page science book. It enables young children (5-10 years old) to independently discover basic concepts in electricity. Materials are included except for the battery. There are 18 projects in Electricity . These include building circuit loops to light lights, buzz buzzers and spin pinwheels . Using the motor and paper discs, children also explore spin art . They build a switch to open and close circuit loops and use the switch to send coded messages to a friend. Children also test which materials conduct electricity and which do not. Thus they learn which materials make good conductors and which make good insulators . By comparing one loop circuits to two loop circuits, they discover the differences between series and parallel circuits . The kit includes a 40 page book, a bulb and holder, an LED, a motor, a buzzer, 4 color coded alligator leads, components to make a switch, a pinwheel, a battery band, cutouts and other parts. The projects require a 1.5 Volt alkaline battery, which can be a AA, AAA, C or D cell. The battery is not included.
