12Set Fruit Battery Science Experiment Kits — complete STEM kits for ages 12 and up Product contents and perkit breakdown Total pack: 12 complete kits. Each kit includes: 4 copper plates, 4 zinc plates, 1 electronic clock, 2 RGB LEDs, 4 wires, and 2 wire clips. Full pack totals: 48 copper plates, 48 zinc plates, 12 electronic clocks, 24 RGB LEDs, 48 wires, 24 wire clips. Key benefits Readytouse classroom or group kits: supplies for 12 learners or 12 small teams, minimizing prep time for teachers and facilitators. Handson STEM learning: students explore how chemical energy converts to electrical energy by building simple batteries from common produce and liquids. Skill development: encourages critical thinking, manual dexterity, circuit assembly skills, and scientific observation. Demonstrable results: when assembled with appropriate fruits, vegetables, or salt solutions, kits can power the included LEDs and electronic clocks to show practical outcomes. What the kit does and how it works Uses copper and zinc electrode plates and the chosen fruit or liquid as the electrolyte to form a simple voltaic cell. Included wires, clips, LEDs, and clocks allow learners to build circuits and test electrical output. Designed for lowvoltage, educational experiments that illustrate basic principles of electrochemistry and electricity. Compatibility and suitable materials Works with a wide range of common electrolytes: oranges, lemons, potatoes, tomatoes, potatoes, pears, pineapple, cola, and prepared salt solutions are all suitable for experiments. Components are sized and configured for studentfriendly assembly and repeated classroom use. Safety and age guidance Intended for learners aged 12 and older. Experiments should be conducted under the direct supervision of an educator or parent. Follow basic laboratory safety and cleanup procedures when handling liquids and produce. Suggested applications and scenarios Classroom labs: distribute one kit per student pair to run simultaneous experiments and compare results across different electrolytes. Science fairs and demonstrations: create visible, interactive displays that power LEDs and clocks to explain electrochemical reactions. Home or afterschool STEM activities: small group projects for handson learning and guided exploration. What you will get A bulk pack containing 12 identical, readytoassemble fruit battery kits, each with electrodes, wiring, LEDs, and a working electronic clock for testing outcomes. Notes on use Prepare fresh fruits, vegetables, or liquids before assembly. Results vary with the type of electrolyte, contact quality, and circuit configuration; combining cells in series or parallel can change the measurable output. Components are intended for educational experiments and repeated classroom demonstrations.
