Springs stretch predictably with added weight.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e \u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eHow to Guide: Make a homemade spring scale with rubber bands to measure weight (mass and gravity). Tape a ruler to a stick. Tie a rubber band to the top and hang a cup from it. Mark “0” when the cup is empty. Add small erasers (each weighs about 10 grams) one at a time. Mark the new spots: “10 grams,” “20 grams,” etc. Now you can weigh different small objects!\u003c\/p\u003e","brand":"KidsLearn","offers":[{"title":"Default Title","offer_id":49000172552419,"sku":null,"price":0.0,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/www.kidslearn.com.au\/products\/force-measurement","provider":"KidsLearn","version":"1.0","type":"link"}
