Design and build an alarmsystem for your bedroom, alight-up Frisbee ® you can useat night, and a fortune-tellingbox that is a new electricversion of the old Magic 8Ball® or the fortune tellersyou see at carnivals. This is avery fun, creative, open-ended challenge that isprobably unlike anything youhave done before. Before you can tacklethese design challenges, youfirst need to learn aboutelectricity, learn how to buildcircuits and switches and howto draw schematics ofcircuits. You will learn how towire series and parallelcircuits, and you need tounderstand how these twodifferent types of circuitswork. You will also learn howto strip and solder wires, aswell as how to use otherbasic tools to build things. Electrical Engineersunderstand how to designand build different types ofcircuits to make electricaldevices, like iPods and TVs,cell phones, kids toys,computers, weather satellites,robotic vacuum cleaners,electric cars, and many otherthings. This workshop willgive you the ability to designand build your own electricalinventions, and give yousome idea of what it is like tobe an Electrical Engineer.

Basic 3™ TrainerElectronic circuits andschematic diagrams can be difficult to understandwhen learning about them.Even simple concepts can bedifficult to grasp! What’sneeded are simple, hands-on activities that explore theconcepts as students learnabout them - KELVIN’s® BASIC 3™ Trainer! The original BASIC 3™ concept and activities were designed and written byEarl D. Gates, the author of Introduction to Electronics: A Practical Approach, 5thEdition, published by Delmar Publishers (see details on page 429). Furtherdeveloped by KELVIN® engineers, the BASIC 3™ Input-Process-Output Trainerintroduces students to electronics in a non-threatening, thematic way. Hands-on activities help students, Gr. 5 & up, explore electronics at their own pace. The compact, assembled trainer features a plug-in motherboard, 6-1/4 x 9-1/4 in. , and built-in sensors. Stackable banana plug leads are used forquick circuitry design and hands-on experiments. The assembled trainer includes: Expandable Motherboard, 9V DC WallTransformer, Stackable Banana Plug Leads, Ten Activity Cards, Design Portfolio,Detailed Teacher’s Guide, and Plug-In Module Ready (additional plug-in modulesfor digital and analog are on the next page).840551 Basic 3™ Trainer ..................................................................$135 or $125 ea./6+840796 Basic 3™ Complete Set (See Details on Next Page)............$895 or $845 ea./3+990136 Stackable Banana Cables ..........................................$29.95 or $26.95 ea./10+

About KELVIN® Electronic Troubleshooting Trainers with Built-In Troubleshooting Teacher Inputs KELVIN’s® Troubleshooting Trainers™ are ideal for middle school students and up. When workingwithin the field of electronics, students should know how to troubleshoot, evaluate, and repairelectronic circuitry. The KELVIN® Troubleshooting Trainers™ are inexpensive and easy to set-upbecause they require no wiring or soldering. Using troubleshooting and problem-solving procedures, KELVIN® Troubleshooting Trainers™

show students how to find a problem on a PC board and then fix it. The trainers were developedto make teaching troubleshooting fast, easy, and effective – with actual electronic equipment,hardware, and pre-wired circuits. According to the experiments, the teacher inserts a problem into the circuit using DIP switches.By following the circuits and measuring the components, students then isolate the trouble andfix it using problem-solving techniques and by resetting the DIP switches.
