2 Table of ContentsWARNING: Always check your wiringbefore turning on a circuit . Never leavea circuit unattended while the batteriesare installed. Never connect additionalbatteries or any other power sourcesto your circuits. Discard any cracked orbroken Supervision:Because children sabilities vary so much, even with agegroups, adults should exercisediscretion as to which experiments aresuitable and safe (the instructionsshould enable supervising adults toestablish the experiment s suitabilityfor the child). Make sure your childreads and follows all of the relevantinstructions and safety procedures,and keeps them at hand for product is intended for use byadults and children who have attainedsufficient maturity to read and followdirections and modify your parts, as doing somay disable important safety featuresin them, and could put your child atrisk of FOR ALL PROJECTS WITH A SYMBOL- Moving parts.

3 Do not touch the motor or fan during not lean over the motor. Do not launch the fan at people, animals, or objects. Eye protection is recommended.!!!WARNING: CHOKING HAZARD-Small parts. Not for children under 3 years.!Conforms toASTMF963-96A Use only AA type, alkalinebatteries (not included). Insert batteries with correct polarity. Non-rechargeable batteries should notbe recharged. Rechargeable batteriesshould only be charged under adultsupervision, and should not berecharged while in the product. Do not mix old and new batteries. Do not connect batteries or batteryholders in parallel. Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium)batteries. Remove batteries when they are used up. Do not short circuit the batteryterminals.

4 Never throw batteries in a fire orattempt to open its outer casing. Batteries are harmful if swallowed, sokeep away from small :!Note:If you have the more advanced Models SC-300, SC-500, or SC-750, there are additional part lists in the other project :If any parts are missing or damaged, DO NOT RETURN TO RETAILER.

5 They aresimple to build and snap circuits kit uses building blocks with snaps to buildthe different electrical and electronic circuits in the block has a function: there are switch blocks, lampblocks, battery blocks, different length wire blocks, etc. Theseblocks are in different colors and have numbers on them sothat you can easily identify them. The circuit you will build isshown in color and with numbers, identifying the blocks thatyou will use and snap together to form a Example:This is the switch block which is green and has the markingon it as shown in the drawings. Please note that the drawingdoesn t reflect the real switch block exactly (it is missing the ONand OFF markings), but gives you the general idea of whichpart is being used in the is a wire block which is blue and comes in different one has the number , , , , or on itdepending on the length of the wire connection is also a 1-snap wire that is used as a spacer or forinterconnection between different build each circuit , you have a power source blocknumber that needs two (2) AA batteries (not includedwith the snap circuits kit).

6 A large clear plastic base grid is included with this kit to helpkeep the circuit blocks properly spaced. You will see evenlyspaced posts that the different blocks snap into. You do notneed this base to build your circuits, but it does help inkeeping your circuit together neatly. The base has rowslabeled A-G and columns labeled to each part in every circuit drawing is a small numberin black. This tells you which level the component is placedat. Place all parts on level 1 first, then all of the parts on level2, then all of the parts on level 3, when the motor is used, the fan will usually beplaced on it. On top of the motor shaft is a black plastic piece(the motor top) with three little tabs. Lay the fan on the blackpiece so the slots in its bottom fall into place around thethree tabs in the motor top.

7 If not placed properly, the fan willfall off when the motor starts to circuits use the jumper wires to make unusualconnections. Just clip them to the metal snaps or :While building the projects, be careful not toaccidentally make a direct connection across the batteryholder (a short circuit ), as this may damage and/or quicklydrain the To Use ItS123456M1B1(Part designs are subject to change without notice).Note:If you have the more advanced Models SC-300, SC-500, or SC-750,there is additional information in your other project manual(s).The base gridfunctions like the printed circuit boards found in mostelectronic products. It is a platform for mounting parts and wires (though thewires are usually printed on the blue snap wiresare just wires used to connect other components, theyare used to transport electricity and do not affect circuit performance.)

8 Theycome in different lengths to allow orderly arrangement of connections on thebase red and black jumper wiresmake flexible connections for times whenusing the snap wires would be difficult. They also are used to makeconnections off the base grid (like the projects using water).The batteries (B1)produce an electrical voltage using a chemical voltage can be thought of as electrical pressure, pushing electrical current through a circuit . This voltage is much lower and much safer thanthat used in your house wiring. Using more batteries increases the pressure and so more electricity slide switch (S1)connects (ON) or disconnects (OFF) the wires in acircuit. When ON it has no effect on circuit press switch (S2)connects (pressed) or disconnects (not pressed) thewires in a circuit , just like the slide switch , such as the 100 resistor (R1), resist the flow of electricity andare used to control or limit the electricity in a circuit .

9 Increasing circuitresistance reduces the flow of photoresistor (RP)is a light-sensitive resistor, its value changes fromnearly infinite in total darkness to about 1000 when a bright light shines on light bulb, such as in the lamp (L1), contains a special wire that glowsbright when a large electric current passes through it. Voltages above thebulb s rating can burn out the motor (M1)converts elecricity into mechanical motion. Electricity isclosely related to magnetism, and an electric current flowing in a wire has amagnetic field similar to that of a very, very tiny magnet. Inside the motor isthree coils of wire with many loops. If a large electric current flows throughthe loops, the magnetic effects become concentrated enough to move thecoils.

10 The motor has a magnet inside so, as the electricity moves the coils toalign them with the permanent magnet, the shaft speaker (SP)converts electricity into sound. It does this by using theenergy of a changing electrical signal to create mechanical vibrations (usinga coil and magnet similar to that in the motor), these vibrations createvariations in air pressure which travel across the room. You hear soundwhen your ears feel these air pressure whistle chip (WC)contains two thin plates. When an electrical signal isapplied across them they will stretch slightly in an effort to separate (like twomagnets opposing each other), when the signal is removed they come backtogether. If the electrical signal applied across them is changing quickly, thenthe plates will vibrate.
