Perfect for STEM education homeschool science classroom learning science fairs Part 1 - Electricity CHAPTER 1 - Get a lightbulb to light In this chapter, you are asked to try to get a lightbulb to light with only one AA battery and one wire. From this experiment, you will learn what a circuit is and how it is formed. Introduced with this project which seems easy but actually requires thinking, users will learn about the conditions of creating current in an electric circuit. CHAPTER 2,8 - Series Circuits & Parallel Circuits In these chapters, you will be guided to hook up a Series Circuit and a Parallel Circuit with batteries, lightbulbs, switches and wires. By making the circuits, you will learn about the difference between Series Circuits and Parallel Circuits, the basic rules they obey and how they are used in real-world physics. CHAPTER 3,7 - Use of an Ammeter and a Voltmeter In these chapters, you will be guided to measure the current in a circuit and the voltage drop across a portion of a circuit. From these activities, you will learn about how to use an ammeter and a voltmeter, how to read the reading, how to draw a circuit diagram and what a short circuit is. CHAPTER 5,6,9,10 - Voltage, Current, Resistance In these chapters, you will be introduced to Resistance and Potentiometers. By doing experiments and recording the results by making diagrams, you will investigate the mathematical relationships between voltage and current and between resistance and current. Finally we come to the introduction of Ohm's law and finish these chapters with a measurement of an unknown resistance by the Current-Voltage method. Part 2 - Magnetism CHAPTER 11 - Learning about magnets You may have observed some effects of magnetism by playing with a magnet. In this chapter, you will learn about the general properties of magnets. When a magnet touches a nail, smaller metal pieces can be attracted to the nail, as shown in the picture. The nail itself becomes a magnet which causes the nail to become polarized. If you pull away the magnet, the nail loses some of its magnetization and will no longer exhibit as much attraction for other metal objects. If you touch a magnet to a piece of soft iron (iron with a low carbon content) replacing the nail, after you pull away the magnet, the iron loses all of its attraction for the other metal objects. This is because soft iron is a temporary magnet. CHAPTER 16 - Electric Generators Did you know a motor can also be used to generate electricity? In this experiment, you will make a hand-crank generator with an electric motor and learn about the working principle of electric generators. The electric generator, invented by Michael Faraday, converts mechanical energy to electrical energy. An electric generator consists of a number of wire loops placed in a strong magnetic field, which is similar to the electric motor. When the wire loops rotate, it cuts magnetic field lines. So the current is generated in a circuit. CHAPTER 17 - Fruit Battery In this experiment, you will make a battery with fruits and learn about the principle of the wet cell battery. The chemistry behind the fruit cell is that zinc is more reactive than copper which means zinc loses electrons more easily than copper. As a result, oxidation occurs in the zinc metal strip and zinc metal loses electrons which then become zinc ions. The electrons then flow from the zinc strip to the copper strip through an external circuit. CHAPTER 18 - Building an Electric Bell In this experiment, you will build an electric bell with batteries and a solenoid and learn the mechanics of the original ranging bell. When the switch is pressed, current flows around the circuit. The soft iron core is magnetized by the magnetic field produced by the current in the coil. Then soft iron armature is attracted and moves towards the soft iron core. Hammer moves to hit the gong and produce a sound. Contacts open to switch off the current. Soft iron core loses its magnetism. Spring brings the soft iron armature back to its original position. Contacts will close to switch on the current again. The process repeats so the bell keeps ringing. Review: Excellent set that starts with tried and true old style basics - 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. Review: Perfect for kids & adults to gain knowledge!! - 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. ## Features - Comprehensive STEM Kit: 50-piece electricity and magnetism set with 40-page full-color manual, perfect for hands-on learning of circuits, electromagnetism, and physics concepts. - 18 Hands-On Experiments: Includes Fruit Battery, Electric Bell, Hand Crank Generator, Double Rail Module, and more to make science fun and interactive. - Parent-Child Discovery: Encourages family science activities, fostering curiosity, observation, and critical thinking skills. - Complete Components: Ampere/voltmeter, lightbulbs, switches, battery holders, resistors, potentiometer, copper & zinc electrodes, bar magnets, horseshoe magnet, compass, solenoid, electric motor, fan blade, hand crank, and stand. - Safe & Educational Gift: Durable materials designed for children 8+, ideal for birthdays, Christmas, school projects, and STEM enrichment activities. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075KPZM5N | | Age Range Description | Kid | | Battery Description | Alkaline | | Best Sellers Rank | #68,083 in Toys & Games ( See Top 100 in Toys & Games ) #658 in Educational Science Kits | | Brand Name | Teenii | | Customer Reviews | 4.4 out of 5 stars 748 Reviews | | Educational Objective | Electricity and Magnetism | | Included Components | Ammeter (0.6A, 3A), Voltmeter (3V, 15V), 4 x Lightbulbs, 3 x Lightbulb Holders, 2 x Switches, 3 x Battery Holders, Resistor Module (5Ω, 10Ω, 20Ω, Unknown), Potentiometer, 3 x Copper Electrodes, 3 x Zinc Electrodes, 1 x Screwdriver, 8 x Wires; Bar Magnet, Horseshoe Magnet, 2 x Circle Magnets, 2 x Permanent Magnets, Compass, Iron Filing Box, Solenoid, Copper Rod, Double Rail Module, Electric Motor M… | | Is Assembly Required | No | | Item Dimensions | 14.76 x 8.07 x 2.76 inches | | Item Type Name | science-kits | | Item Weight | 1.05 Kilograms | | Manufacturer | Shenzhenshileanbokejiyouxiangongsi | | Manufacturer Maximum Age (MONTHS) | 216.0 | | Manufacturer Minimum Age (MONTHS) | 96.0 | | Manufacturer Part Number | US-PK-001-YE | | Material Type | Plastic | | Model Number | US-PK-001-YE | | Size | 14.7 inches x 8.2 inches x 2.8 inches | | Theme | Physics | | UPC | 746591873486 | | Unit Count | 1.0 Count | ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/81pjkMSX7ML.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71boEpP2ddL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/71lZO4qoY3L.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71Hd16JFydL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/81ZnTJcDqUL.jpg) ## Questions & Answers **Q: Students are neglectful and have lost pieces. Where could I get replacements?** A: Hello Jason, I am sorry for all the inconvenience caused. Although I work hard to ensure high quality standards through multiple quality checks, I regrettably still come across missing and defective parts occasionally. Please contact us (we are the seller of the product on amazon) You may be surprised when you receive the replacement and found that it is a whole new kit. This is because we don't sell parts separately on Amazon and if we send you from China where our company is located in, it would be a very long time for you to wait. So I finally decide to send you a whole new kit from Amazon warehouse. I hope that this new kit will help you solve the problem.
 Best regards, Calvin **Q: We bought this but are having a hard time following along. is there another resource you could direct us to for further explanation? (like you tube?)** A: Just bought mine and I find it does take time to absorb . I have expanded into simple circuits as opposed to going on with the other experiments. Enough for me to start to learn the basics. I hope to try them all so that I can later go over them with my Grandchildren. I find very interesting equipment for learning at hBarsci,com. But these are additional learning tools. **Q: Are the instructions available in spanish? my grandsons are peruvian and have very limited english** A: Yes, We have the instruction in 6 languages including English, French, Germany, Spanish, Italian and Japanese. Although we only provide the English version of instruction on amazon.com, you can contact us at teenii@foxmail.com and we will send you the link to download the electronic version of the instruction in any other language. **Q: What age levels can this be used with?** A: This kit is more suitable for kids who 12-year-old and up because they already have some reading skill and the ability to better understand the scientific concept and definition. They are also at the age when they will learn knowledge about electricity at school. With this kit, they can enhance what they learned or study in advance. For younger kids, they should be under parents' supervision and guidance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent set that starts with tried and true old style basics *by T***S on January 4, 2021* 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.
