Znatok Electronic Construction Set 999connections

Constructor ZNATOK School 999 schemes + - a special version of the electronic constructor for educational institutions, intended for the organization of practical classes in physics as part of studying the "Electricity" course. It will clearly demonstrate the principles of operation of a diode, a transistor, a photoresistor, a radio receiver, and many other devices and appliances. The instruction for the educational and practical part contains a description of 21 practical classes for the school. The original method of connecting parts provides a quick and effective result without the use of soldering. The designer was tested in schools and other children's institutions and received a high rating from experts. Practical classes are coordinated with the existing school program and physics textbooks of the 8th, 9th, 10th and 11th grades.

Tasks are divided into 3 groups of different levels of difficulty:

• Blue - entry level
• Green - medium level
• Red - above average level.

With the help of the designer, you can collect:

FM radio - volume control, automatic tuning to the station.

Measuring circuits (voltmeter, ammeter) - 75 variants of circuits.

Voice recorder (recording / playback).

Lie detector.

Light indicator - letters (upper and lower case) and numbers.

Automatic lights - "reminder" about the onset of darkness, rain sensor, night light.

Musical doorbell with control options.

Sound simulators - 12 variants, 120 variants of schemes.

Security alarms - frightening sounds, sound/light reaction to a wire break.

Adjustable metronome.

The set includes 2 manuals, with the help of which you can assemble more than a thousand electrical circuits, which allow you to learn the basics of controlling light, sound, electricity and water in practice. Categories of child development: fine motor skills, attention, logic, memory, mathematical abilities. 4xAA batteries are required. Recommended for children aged 5 years.
