KOSMOS Elektro & Co. Electronic Circuit Building Kit (60 Experiments) - An essential STEM tool to inspire children's scientific potential.

Want your child to grasp the core mysteries of physics through play? Developed by KOSMOS , a century-old German science education brand, the "Elektro & Co." electronic circuit building kit is a deep science exploration platform designed specifically for children aged 8 to 14. This curriculum visualizes abstract electrical and magnetic concepts, allowing children to build their own electronic world through intuitive, pluggable building blocks.

🔧 Assembly difficulty:

🔧 Assembly difficulty: Medium to high (Suitable for ages 8 and up or for parents and children to explore together, challenging logical thinking)

Core Educational Values: In-depth Exploration of Four Knowledge Systems

This set is more than just a simple toy; it's a systematic physics curriculum covering the four most fundamental areas of modern technology:

Knowledge domain Learning Focus and Practice
Electrical Engineering Learn the basic logic of series and parallel circuits, master the principle of switch control, and practice basic communication technologies such as Morse code transmission.
Motors Explore how electric current is converted into kinetic energy. Through building a small fan and an automatic alarm system, understand the advanced applications of motor rotation and lighting linkage.
Magnetism Experience the invisible magnetic field firsthand. Experiments cover the principles of the compass, magnetic levitation, and magnetic fishing, establishing the concepts of magnetic poles and magnetic field lines.
Electromagnetism Revealing the interaction between electricity and magnetism. Building an electromagnet and testing its penetrating power to understand the key role of electromagnetic induction in navigation and horn devices.

60 Heuristic Experiments: A Scientific Journey from Basic to Advanced

The set includes 60 carefully designed experiments, each aimed at developing children's observation and problem-solving skills:

Starting with the most basic "two-light experiment," children will gradually challenge themselves with "burglar alarm systems" and "two-way control switches in corridors." These experiments are not just about assembling parts, but about applying physics textbook theories to real life. For example, through "lights emitting Morse code," children can understand the principles of early long-distance communication; while the "electric motor and light bulb" experiment demonstrates the amazing process of energy conversion.

Product Features and Modular Design

To ensure a smooth and safe learning process, KOSMOS's design reflects the meticulousness of German craftsmanship:

  • Plug and play connectors: Unique cross, L-shaped, and T-shaped connection modules with clear line indicators significantly reduce the risk of incorrect connections and enhance the sense of accomplishment in assembly.
  • Inquiry-based learning: Accompanied by a 64-page bilingual (Chinese and German) instruction manual, it guides children through the complete scientific process of "formulating hypotheses → conducting hands-on experiments → analyzing data → drawing conclusions".
  • Authoritative Certification: Awarded the Parents' Choice Gold Award in the United States , its educational value and product quality have been highly recognized by international professional organizations.

How to Choose Age-Appropriate Toys?

Struggling to find the right toy or birthday gift? Kidrise has the perfect guide for you!

Toys are essential partners for children to learn while playing. Regardless of the type, they hold educational value.
However, choosing toys that do not match a child's age may lead to disinterest or safety concerns.

Kidrise Expert Advice:
Match the child's developmental age (intelligence, motor skills, and physical ability). Choosing 'slightly challenging' toys can better stimulate a child's potential.
