Electrical starter kit for learning basic circuits and electric current. Designed for classroom and home use, the kit helps children practice building series and parallel circuits while reinforcing textbook concepts. Key benefits Handson learning: Build simple loops, series circuits, and parallel circuits to deepen understanding of electric current and circuit basics. Curriculum support: Suitable for grade 3 to grade 5 science projects and recommended for children aged 4 to 9 for guided activities. Versatile teaching aid: Useful for classroom demonstrations, summer camps, science fairs, practice centers, science clubs, and homeschool units. What is included Resistance x4 Single pole switch x3 No. 1 battery box x4 Wire Product details Size: 36*24cm / 9.4*14.1in Weight: 772 grams Function: Assemble various series and parallel circuits using the provided components Typical use scenarios Classroom lesson: Demonstrate the difference between series and parallel circuits during a science class and let students assemble and test circuits in small groups. Science fair project: Use the kit to create a clear, handson exhibit that shows how circuit configuration affects brightness and continuity. Homeschool or club activity: Provide guided practice for children to build circuits, test components, and record observations as part of a structured learning unit. Precautions Allow 1 to 3 mm measurement variance due to manual measurement. Colors may vary slightly from images because of picture positions and lighting.
