作者:505 陳品熙、林奐、萬哲維、林勁存 指導: 潘蓮菁 老師 壹、研究動機 五上自然課「空氣與燃燒」的單元提到小蘇打粉加 醋會產生二氧化碳,可用來製作簡易滅火器。 我們想知道: 有沒有其它的材料也可以產生二氧化碳? 各式各樣不同材料所製作出來的滅火器,到底 哪一種的效果會比較好,穩定性較高? 貳、研究目的 一.找出可以用來製造二氧化碳的材料。 二.調配不同濃度的醋與定量的小蘇打粉混 合,探討對滅火效果的影響如何。 三.探究噴頭數量的多寡對滅火效果的影 響。 四.變更不同材質噴管,探討所產生的滅火 效果是否有所差異。 五.設計一個穩定性較高的簡易滅火器。 參、研究器材 香檳瓶(370cc)、雪碧瓶(600cc)、可樂瓶(600cc)、優格瓶、養樂多瓶、吸管、硬塑膠管、橡 皮管、透明軟管、鐵釘、鐵鎚、老虎鉗、剪刀、美工刀、抹布、小蘇打粉、泡打粉(含小蘇打 粉及酒石酸)、麵粉、太白粉、地瓜粉、洗衣粉、氨粉、麵食發粉、糖、蛋殼、貝殼、糯米醋、 烏醋、鳳梨醋、檸檬、柳丁、酸性水、水生池的水、廣用試紙、蠟燭、火柴、量筒、燒杯、 玻棒、透明膠帶、標籤、相機、尺、水壺、粉筆、黏土、碼表、水、塑膠筒、湯匙、漏斗 肆、研究過程與結果 實驗(一):找出可以代替醋和小蘇打粉產生二氧化碳的材料 糯米醋 柳丁水 檸檬汁 酸性水 鳳梨醋 水生池 烏醋 洗碗精 酸性液體 + 小蘇打粉.
