雞蛋有多硬? 圖片參考：http://www.scienceprojectideas.co.uk/images/27483.jpg 如何用科學實驗證明雞蛋有多硬? 蛋殼硬度实驗:蛋殼可以支持多少本書?放4個瓶蓋在桌子上(下面放很多報紙）,把整個雞蛋（生的或煮熟的），小的一端朝下，放在瓶蓋上。小心翼翼地把一塊木板放在雞蛋上，然後慢慢地在上堆積書籍，直到蛋殼破裂，然後秤書籍。嘗試用橫置的雞蛋做, 看是否能支持相同數量的書籍？Put four bottle caps on the table (with lots of newspaper underneath) and balance whole eggs (raw or hard-boiled), small end down, in the bottle caps. Carefully put a wooden board on top of the eggs, and then slowly pile books on top until the eggshells break and then weigh the books. Try it with eggs balanced on their side – do these support the same number of books?
