The snap circuit kit uses building blocks with snaps to build the different electrical and electronic circuits in the projects. Each block has a function: there are switch blocks, lamp blocks, battery blocks, etc. These blocks are in different colors and have numbers on them so that you can easily identify them.
The circuit you will build is shown in color and numbers, identifying the blocks that you will use and snap together to form a circuit. The Snap Circuits 300 set contains over 60 parts so you can build over 300 exciting projects or create your own exciting experiments. An instructional manual is included with complete directions to build Projects #1- #305.
Have fun learning about electronics while you build an amplified musical bell, a screaming fan, a voice controlled burglar alarm, an AM radio and much more! Four "AA" batteries and a 9V battery are required (not included). Recommended for ages 8+.
