泰山壓頂 班級:六乙 成員:許哲毓.呂則緯.何宜珊
研究動機 • 因為看到了新聞報導上的農業植物生長速度都很慢,所以我們就找看看哪種方式能讓植物長的更快。
研究目的 • 我們想了解重物壓在土壤上,植物會不會長的比較高。
研究問題 • 壓重物能刺激植物生長嗎? • 沒有壓重物的植物會長的比較高嗎?
實驗器材 • 四季秋海棠21盆 • 寶特瓶18罐 • 瓦楞板1片 • 標籤紙6張 • 盆栽6盆
將植物栽種到圓形盆栽內 實驗步驟1
實驗步驟2 • 將瓦楞板裁切成橢圓形(一盆種3株)
實驗步驟3 • 將以裁切好的瓦楞板放入盆栽內
實驗步驟4 • 將分別裝了0公克 200公克400公克水量的寶特瓶放入盆栽內
實驗步驟5 • 每天澆水並觀察紀錄
我們的發現 • 有些比其他長的更高 。 • 有些植物有變矮。
