    【課程】STEM課程之實驗報告

    發布日期: 2016-09-22 瀏覽次數:

                      第二小組實驗報告  執筆:初二(2)班  史文佳

    發現與定義問題:

    1.你的方案主要解決什么問題?

    哪種方法可以保護小河道河岸,可以更好地防止水土流失。

    2.為什么要解決這個問題?

    防止水土流失引起更大的環境問題,改善自然環境。

    3.在制定護岸措施時需要考慮哪幾個重要因素?
        ?河道的傾斜角度。傾斜角度越大,水土流失越嚴重。

    ?灌進河道的水的數量。水越多,水土流失越嚴重。

    ?河道中遮擋物的數量。遮擋物越少,水土流失越嚴重。 

    設計解決方案:

    1.材料使用

    牙簽、美工刀、剪刀、尼龍紗網、沙土、水、擠塑板、熱熔膠槍、量杯、水桶

    2.分工安排

    職務

    人員

    工作內容

    項目管理員

    周程文、沈天辰

    管理項目的分工安排,明確每個組員的職責。

    調研員

    陳諾、史文佳

    調查河道的多項具體數據。

    設計師

    周程文、沈天辰、周伊洋

    根據調研信息,設計防止水土流失的方案并且繪制草圖。

    工程師

    周程文、沈天辰、周伊洋、陳諾、史文佳

    根據圖紙開挖河道,并根據兩種解決方案建造河岸防護措施。

    測量師

    史文佳

    對護岸工程完成前后的河道進行最少三次測試,收集數據,進行記錄與分析。

    攝影師

    周伊洋

    為河道開挖、建筑護岸工程等拍照。

    3.測試步驟

       第一步:裁剪擠塑板

       第二步:組裝擠塑板成所需河道

       第三步:用熱熔膠槍加固

       第四步:添加擠塑板制成的遮擋物

       第五步:插牙簽制成的植被

       第六步:添加所需的沙子

       第七步:倒入測試所需的水

       第八步:測量收集到的水的體積、水中泥沙的數量。

    制作與測試:

    1、初始河道數據

    測試

    倒入的水的體積

    收集到的水的體積

    水中泥沙的重量

    觀測結果

    第一次

    450ml

    約425ml

    約250g

    較差

    第二次

    850ml

    約825ml

    約400g

    較差

    2、方案一(添加擠塑板塊)測試數據

    測試

    倒入的水的體積

    收集到的水的體積

    水中泥沙的重量

    觀測結果

    第一次

    450ml

    約350ml

    約15g

    稍好

    第二次

    850ml

    約700ml

    約31g

    稍好

    3、方案二(在河道上添加尼龍紗網)測試數據

    測試

    倒入的水的體積

    收集到的水的體積

    水中泥沙的重量

    觀測結果

    第一次

    450ml

    約350ml

    約12g

    較好

    第二次

    850ml

    約675ml

    約25g

    較好

    分享與改進:

    1.比較三組數據及觀察,描述不同?

         其他變量相同的情況下,尼龍紗網能比遮擋物更好地防止水土流失。

    2.實驗結果符合設計方案的初衷嗎?

        方案一良好,方案二有進步空間

    解釋為什么你這樣打分?

    因為前兩次實驗后河道上的沙子全濕了,影響了試驗的準確性。

    2、做什么改變可以讓方案更好?
        每做完一次實驗換掉沙子并清理河道。
