With a consistent diameter of 15.5mm and durable coil construction, this spring allows students to examine key scientific concepts like tension, compression, energy transfer and Hooke's Law. Its compact yet robust form is suitable for repeated hands-on use in classroom experiments or student-designed prototypes, providing a foundation for...\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eEducational Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eIllustrates elastic potential energy and spring force in a controlled setup\u003c\/li\u003e\n\n\u003cli\u003eReinforces principles of mechanical physics and Hooke's Law\u003c\/li\u003e\n\n\u003cli\u003ePromotes measurement, hypothesis testing and analytical skills\u003c\/li\u003e\n\n\u003cli\u003eEncourages exploration of real-world applications such as suspension systems\u003c\/li\u003e\n\n\u003cli\u003eIdeal for STEM and STEAM projects requiring functional components\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eClassroom Ideas:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eUse in a force vs. extension experiment to calculate spring constants\u003c\/li\u003e\n\n\u003cli\u003eIntegrate into student-built structures and kinetic energy models\u003c\/li\u003e\n\n\u003cli\u003eDemonstrate energy transfer by attaching weights and measuring extension\u003c\/li\u003e\n\n\u003cli\u003eCompare to other spring types for a discussion on design and functionality\u003c\/li\u003e\n\n\u003cli\u003eExplore safety systems (e.g. car seats or shock absorbers) by modelling with the spring\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 15.5mm\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eCoiled Length:\u003c\/strong\u003e 20mm\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 55mm\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter:\u003c\/strong\u003e 0.7mm\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eRecommended Age:\u003c\/strong\u003e 8+\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUnits:\u003c\/strong\u003e Each\u003c\/li\u003e\n\n\u003c\/ul\u003e","brand":"Modern Teaching Aids NZ","offers":[{"title":"Default Title","offer_id":42238867636337,"sku":"SER1005002","price":11.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/7633\/6753\/files\/ser1005002_spring-balance-8211-dual-scale-8211-500g-8211-5n-8211-green.webp?v=1760001922","url":"https:\/\/teaching.co.nz\/products\/spring-balance-dual-scale-500-g-5n-green","provider":"Modern Teaching Aids NZ","version":"1.0","type":"link"}
