Each bar features a bimetal strip mounted within an insulating plastic handle. When heated, the two metals expand at different rates, causing the bar to bend and demonstrating how thermostats respond to temperature changes. This hands on model helps students understand heat behavior and material properties through direct observation. Designed for repeated classroom use, the pack of 10 is ideal for group demonstrations and lab activities. Product dimensions for each bar are approximately 0.7 inches long x 0.7 inches wide x 9.75 inches high. Instructions are included.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Features\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"3111\" data-end=\"3165\"\u003eDemonstrates thermal expansion using a bimetal strip\u003c\/li\u003e\n\u003cli data-start=\"3168\" data-end=\"3225\"\u003eVisible bending action illustrates thermostat operation\u003c\/li\u003e\n\u003cli data-start=\"3228\" data-end=\"3278\"\u003eInsulating plastic handle supports safe handling\u003c\/li\u003e\n\u003cli data-start=\"3281\" data-end=\"3329\"\u003ePack of 10 supports classroom group activities\u003c\/li\u003e\n\u003cli data-start=\"3332\" data-end=\"3375\"\u003eIncludes instructions for guided teaching\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GSC International Inc.","offers":[{"title":"Default Title","offer_id":46229160198283,"sku":"GS-4-30901-10","price":71.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0339\/3863\/6939\/files\/4-30901-10-photoroom.jpg?v=1773843621","url":"https:\/\/uberbazaar.com\/products\/compound-bar-metal-plastic-9-75-h-heat-expansion-science-pack-of-10-by-gsc-international","provider":"Uber Bazaar","version":"1.0","type":"link"}
