Let your child have endless fun learning to build circuits with these colorful electronic Snap Circuits. Each one features more than 60 parts that easily snap together. The Snap Circuits Classic can be used to make interesting circuits, encouraging educational play that teaches your future engineer about electricity. All of the parts have colored graphics that represent their real electronic names and symbols. This educational toy comes with a complete instruction manual and project guide that helps you to guide your child through exploring over 300 experiments. Some of the projects include making circuits for doorbells, radios, alarms, flash lights, laser light, street lamps, a lie detector and a fan Modulator. This kids' Snap Circuits toy runs on four AA batteries that are sold separately. It is ideal for children age 8 years and older. Snap Circuits Classic comes with over 60 parts to create 305 different electronic projects. The parts, which include snap wires, a slide switch, a resistor, a microphone, and capacitors, snap together easily onto the included plastic grid-no soldering required. Each part is numbered and color-coded to make identifying them easy. These parts combine to create working circuit boards just like the ones found inside televisions, radios, and other electronic devices. With its easy-to-follow instructions, Snap Circuits gives your child a hands-on education in how electrical circuits run the everyday devices that they're familiar with. They'll also gain valuable lessons in building and in following instructions. The project manuals include large color illustrations and simple directions for each project. the projects are arranged in order of complexity, kids can build on their skills as they progress through the manual. The lessons start out with a simple electric light and switch project that demonstrates how electricity is turned on and off with a switch. Further along, kids can put together a fire fan symphony, a water-detection alarm, a delayed-action fan, and more. Once children have mastered several of the techniques introduced in this kit, They can use the parts to experiment and create their own customized circuits and electronic devices. Snap Circuits SC-300 requires four AA batteries, which are not included. What's in the box: plastic snap-grid, 61 electrical parts, and 1 Project manual containing projects 1-150.
