1 WANT TO LEARN MORE ABOUT ELECTRONICS USING SNAP CIRCUITS? The project manuals include a brief description of how your parts work (the About Your Snap Circuits Parts page) and the projects you build are great for learning about electricity, electronics, and science. But for anyone who wants to learn more Elenco Electronics also offers a complete lesson in basic electronics, called the Student Guide. The Student Guides for the Snap Circuits product are a tool for opening the exciting world of electronics. Following the Learn by Doing concept, electronics will be easy for students to understand by using Snap Circuits to build circuits as they learn about them. The Student Guides emphasize the practical applications of electronics, without bogging down in mathematics. The lessons are as much about science as about electronics. Why should students learn about electronics? Electronics plays an important and increasing role in their everyday lives, and so some basic knowledge of it is good for all of them. Learning about it teaches how to do scientific investigation, and the projects develop basic skills needed in today's world. Several Student Guides are available, depending on which Snap Circuits product you have. The table of contents for each is listed below, along with a sample page. Student Guides Educational Series - Teaches about Basic Electricity & Electronics in the everyday world using our Learn By Doing Ò concept! Student Guide Junior $ full color pages (for use with SC-100 set) Student Guide $ full color pages (for use with SC-300/500/750 sets) [does not require Student Guide Jr.] These may be purchased using the Replacement Parts Order Form on the Snap Circuits website ( -1-

7 Water flowing under pressure in a pipe or a fastmoving stream can be used to turn a paddlewheel. If the paddlewheel was linked to a fan blade then you could use the water pressure to turn the fan, perhaps to cool yourself on a hot day. If the water was flowing very fast due to high pressure, then you could get the fan moving fast enough it might create a strong airflow like a propeller on a plane. TYPICAL PAGE IN A STUDENT GUIDE A similar thing happens in a motor, with electricity instead of water. A motor converts electricity into mechanical motion. Snap Circuits includes one motor, shown here with its symbol. Snap Circuits also includes a fan, which is used with the motor. An electric current in the motor will turn the shaft and the motor blades, and the fan blade if it is on the motor. Motor Symbol Motor (M1) Fan Blade How does electricity turn the shaft in the motor? The answer is magnetism. Electricity is closely related to magnetism, and an electric current flowing in a wire has a magnetic field similar to that of a very, very tiny magnet. Inside the motor is a coil of wire with many loops, if a large electric current flows through the loops the magnetic effects become concentrated enough to move a small magnet. The motor also has a small magnet, on a shaft. When electricity moves the magnet, the shaft spins. If the fan is on the motor shaft then its blades will create airflow. Consider this circuit (which is project 2): Power Contacts Magnet Shaft Electromagnet -17- When the switch is on, current flows from the batteries through the motor making it spin. The fan blades will force air to move past the motor. Be careful not to touch the motor or fan when it is spinning at high speed.
