Fun Circuit Building Experiments for Beginners Construct circuits with colorful electric building blocks to learn about electricity and how electronic devices work. With the innovative snap-together blocks in this kit, children eight and up can safely and easily begin experimenting with electronic circuits. These building blocks are specially designed to make learning electronics fun and accessible. Because the blocks are brightly colored and have unique shapes, it is easy to follow the assembly diagrams to construct functional circuits. And because the circuit symbols are printed directly onto the blocks, you can quickly become familiar with the symbols and learn how to read circuit diagrams. The fun building projects include an alternating blinker, a police siren, an ambulance siren, an alarm system, a light detector, a conductivity tester, a rain warning system, a timer, and logic circuits. The electronic components in this kit include capacitors, resistors, transistors, LEDs (light emitting diodes), a phototransistor, a switch, 30 contact blocks, cable blocks, a battery holder, a speaker, and a sound integrated circuit. The 64-page, full-color experiment manual guides you through 70 circuit building experiments with easy-to-follow diagrams. This kit provides kids with the tools and instructions they need to experiment with their own hands and learn firsthand how electronics work.

• Install a sound module to generate the sounds of police cars
• Learn the important role resistors and potentiometers
• Use a multimeter to measure invisible voltage and current
• Use a FM radio module to build an alarm clock
Tap into the awesome world of electronics with this advanced system of snap-together electric building blocks. Start out by experimenting with colorful light-up circuits as you dive into the basics of electricity. Install a sound module to generate the sounds of police cars, ambulances, or fire engines. Learn the important role resistors and potentiometers (variable resistors) play in an electronic circuit. Use a multimeter to measure invisible voltage and current flowing through your circuit. Investigate transistors in switches and amplifiers to learn how the logical circuits in computers work. Build circuits that use sensors to detect moisture, temperature, and visible light. Incorporate capacitors in your circuits to store and discharge electricity for specific functions, such as a countdown clock and a red-green alternate flasher. Test out the indispensable 555 timer to build some complicated circuits. Use an operational amplifier and an FM radio module to build an alarm clock. This kit uses the same unique electric building blocks as our other electronics kits, with the addition of many new advanced components, allowing you to build more complex circuits. The more than 140 electronic components include capacitors, resistors, transistors, LEDs (light emitting diodes), phototransistor, switches, speaker, integrated circuit, infrared LED, diodes, FM tuner, 555 timer, operation amplifier, two potentiometers, electrodes, voltage and current meter, microphone, and 9-volt battery pack.
The manual contains detailed illustrations and explanations of 24 hands-on experiments that can be conducted using the GENECON and the GENECON Kit. Concepts covered range from circuit types to principles of electromagnetism. This is a must-have manual for every science curriculum.
Two plates 250mm in diameter are supported in two rigid uprights and driven by hand in opposite directions. They are heavy, high-resistance plastic with sectors of aluminum sheets. Leyden jars (condensers) made of borosilicate glass and aluminum foil store electricity until discharged by the dischargers. The whole unit is mounted on a wooden base.
This pre-assembled DC motor is designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current. The DC motor can stand vertically or horizontally and operates on a 1.5V battery (not included). It comes in a sturdy plastic storage case with a student activity manual Shipping weight: 11.45 oz., dimensions: 5.5" x 4.5" x 2.5".
