{"product_id":"lionhvdg","title":"Hand Crank Van de Graaff","description":"\u003cp\u003eTurn science into a spectacular experience with the Hand Crank Van de Graaff generator. With a simple rotation of the handle, this impressive device builds static electricity on its polished metal dome, creating visible and exciting electrostatic effects. It transforms abstract energy concepts into dramatic, hands-on demonstrations that capture attention instantly. Ideal for structured science lessons, this generator allows educators to clearly demonstrate charge build-up, discharge and electrical forces in a safe, controlled way.\u003c\/p\u003e\n\u003cp\u003eDesigned for reliability and consistent classroom performance, the sturdy construction and manual operation allow full control over the amount of charge produced. Supplied with engaging accessories, this model makes it easy to demonstrate multiple electrostatic effects straight out of the box, keeping science lessons dynamic and interactive.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEducational Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDemonstrates static electricity and charge accumulation in a highly visual way\u003c\/li\u003e\n\u003cli\u003eStrengthens understanding of energy transfer and electrical forces\u003c\/li\u003e\n\u003cli\u003eEncourages scientific reasoning through prediction, testing and observation\u003c\/li\u003e\n\u003cli\u003eBuilds confidence in exploring foundational physics concepts through guided experiments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClassroom \u0026amp; Play Activity Ideas:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUse the ribbon plume to dramatically show charge repulsion in action\u003c\/li\u003e\n\u003cli\u003eSpin the electrostatic spinner to demonstrate energy transfer\u003c\/li\u003e\n\u003cli\u003eIlluminate the neon wand to visualise electrical discharge\u003c\/li\u003e\n\u003cli\u003eRotate small group stations where learners test each accessory and record observations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMeasurements: 38 (L) x 76 (H) x 23 (W) cm\u003c\/li\u003e\n\u003cli\u003eWeight: 4.56 kg\u003c\/li\u003e\n\u003cli\u003eHand-crank operated electrostatic generator\u003c\/li\u003e\n\u003cli\u003eIncludes 3 accessories: \n\u003cul\u003e\n\u003cli\u003eribbon plume\u003c\/li\u003e\n\u003cli\u003espinner\u003c\/li\u003e\n\u003cli\u003eneon wand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpare charging belt and O-ring included\u003c\/li\u003e\n\u003cli\u003eSafety Information: Use under supervision; avoid direct contact with the dome during high charge; operate in dry conditions for optimal performance\u003c\/li\u003e\n\u003cli\u003eRecommended Age: 12+ years (adult supervision required)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Modern Teaching Aids NZ","offers":[{"title":"Default Title","offer_id":43650133950577,"sku":"LIONHVDG","price":287.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/7633\/6753\/files\/lionhvdg_hand-crank-van-de-graaff_v2_1.webp?v=1784151779","url":"https:\/\/teaching.co.nz\/products\/lionhvdg","provider":"Modern Teaching Aids NZ","version":"1.0","type":"link"}
