Teenii Electricity and Magnetism Kit for Kids, STEM Science Experiments with Electric Circuits, Educational Physics Toy, Science Discovery Game for Boys and Girls 8+, 50 Pieces

I'm an electrical engineer, and when I began with electronics around age 10, I used a simple kit that included basic switches, wires, resistors and electromagnets. It was old school, ... but old school taught the basics in a very lucid manner that made the concepts of voltage, current, and resistance stand out. In today's world, there are sets like Snap Circuits, but the only lesson that most children take away from those kits, ... is how to snap stuff together. They are not learning the proper conceptualization behind V= IR. Snap Circuits teaches nothing about the total flowing number of electrons per unit time (the current), .. nor does it give children a good idea of how watts actually means the amount of electrical work done (or how this can be expressed as an easy integral). This kit begins with the most basic of basics, ... one battery, one wire and one light bulb. From there it progresses through 17 different important aspect of simple circuits. And the components are high quality and arranged neatly. Each experiment demonstrates a clear concept even to children who typically find electronics and electricity confusing. I have used this set with my son for almost two years now, and I would rate it five stars. Good for parents and excellent for schooling supplementation.

I bought this for myself so I can learn more about electrical circuit’s & components. I am a 100% hands on learner so books & online classes are no help to me. I am a 26 year old mechanic. Electrical work has never been my specialty so I bought this to learn and better my skills. This kit is absolutely amazing and worth every penny, by far the best kit to buy.

The parcel was partially damaged (or have been opened by the PostOffice?) but all the items were complete. The booklet is in English which surprised me a bit but the text is clear and easily comprehensible. All the items are of good quality and conform with the description. The goal of the kit should be satisfying.

Very nice clear and basic STEM kit. The instruction book was surprisingly well written with clear experiments and exercises. For the younger kids, it offers them their first opportunity to see the value of a data table and learn how to create and interpret a simple graph. My set came with a malfunctioning compass and was missing the horseshoe magnet. This issue was addressed by Teenii within 24 hours. Great customer service/support. Will probably be buying their associated optics kit after we finish with the electronics and magnetism kit.

Looks like child intent but is very suitable for adult. The components are large and colorful which makes them look toyish but they are easy to handle. I chose it for simplicity in basic Ohms law to begin to train my teenage grandson before robotics. I had fun reviewing the manual which is comprehensive but easy on the eyes and brain. The schematics are large and plainly drawn. Math formulas are plainly presented and well instructed. The separate volt-meter and ammeter, and that they are analog rather than digital, is a plus.

The parts aren’t all there. I have a missing piece a solenoid. And the copper tube is not copper it resembles brass and as a result it doesn’t work.

It is very useful and funny and good made kite

My son got set for his 7th birthday. Is not yet in the age recommendation but good. He is interested in switches and the meters. He has a lot of fun connecting the elements. He does not use the book in a grand manner. He did not use the magnet that great, though. He can work on it for hours and build circuits and have fun with it. I can also explain a lot to him. Nice set and a nice toy for my son.

A very good educational kit with many experiments on the cause and effects of various electrical components. . .

We received our kit and all components were accounted for and were high quality. Not cheap flimsy plastic. Magnets are strong and responsive. Unfortunately, our instruction manual was misprinted and we couldn’t read a lot of the instructions, so I contacted the Teenii company directly and they sent out another full kit immediately. Very pleased with their prompt customer service.

以下の長所・短所を勘案、日本の子供向けにきちんと書かれた電気・磁気に関する別の解説書に従って、この商品で提供されるパーツを用いて実験を行うというのが現実的な使い方と思う。 長所：小中学生が電気・磁気の働きについて実験し、理解するために必要なパーツを6,000円以下という低価格で概ね一通りそろえている。（エナメル線を別途購入すると実験の範囲が広がる。）発光装置がLEDではなく豆電球、抵抗器の導線がむき出し等、原理が理解しやすい部品構成となっている。付属の磁石の磁力も強力で各種の実験を確実に行うことができる。 短所：電圧計・電流計や各部品の精度の問題か、端子と導線の接続精度の問題か当方にツールの持ち合わせがなく判定できないが、各種の測定精度が低い。定性的な理解は可能だが、定量的な考察は難しい。あくまでおもちゃの域を出ない。また、「実験マニュアル」が日本の子供向けではない。特に本マニュアルではフレミングの「右手」の法則を扱っているが、日本で中学生までで教えるのはフレミングの「左手」の法則。一方、マニュアルには「左手」の法則への言及がない。また、解説の日本語はかなり自然な日本語になってはいる（漢字の一部は日本語の漢字になっていないけれど）が、8+歳の子どもが理解しやすい文章になっていない。（マニュアルの品質が改善されれば★4つの可能性あり。）

Articolo adattissimo per un bambino di 9 anni, sviluppa concentrazione, attenzione e interesse. È più che un gioco. Ottimo prodotto

A good set enjoyed by my 10 year old electronic loving son. We bought a buzzer to go with it and some crocodile clip wires so he has more flexibility. He used some wire to make a buzz wire challenge. There are a few elements he doesn’t understand yet. It’ll keep him busy for a couple of years. Recommended.
