    湖北監利:活用鄉土資源開展科普活動

    發布時間:2019-07-05 09:40 編輯:涪陽小學王老師

    “螢火蟲是一種益蟲,它是蝸牛、鼻涕蟲的天敵”“螢火蟲是生態環境指示生物,它對水域污染、土壤污染都很敏感”“保護螢火蟲就是保護人類賴以生存的環境”“前天晚上,我和爺爺在大垸農場長江段岸邊發現那里的蘆葦中有許多螢火蟲一閃一閃的,爺爺說他好像回到了童年。這是因為長江大堤上沒有種莊稼,沒有使用農藥、化肥,更沒有使用除草劑,這里的土壤和水質保護得比較好”……

    這是近日發生在湖北省監利縣黃歇小學科學討論會上的一幕。

    日前,監利縣組織鄉村中小學圍繞“讓螢火蟲回到我們的身邊”科普活動,在青少年中開展“科普閱讀,走近螢火蟲”“科學考察,認識螢火蟲”“科學探索,喂養螢火蟲”“科學實踐,調查螢火蟲”“科普宣傳,保護螢火蟲”系列活動,在引導鄉村青少年傳遞保護螢火蟲、保護環境理念的同時,關注和保護其他有益生物。

    “螢火蟲是生態環境的指示物種,凡是有螢火蟲種群分布的地區,都是生態環境保護得較好的地方。我們在青少年中開展保護螢火蟲教育活動,是為了從小在鄉村孩子的心中播下一粒保護生態環境的種子,并通過學校教育學生、學生影響家庭、家庭帶動社區,從而喚醒人們保護生態環境的意識。”湖北省特級教師、監利縣青少年科普教育專業委員會理事長鄧從新說。

    此前,黃歇小學602班學生章夢妍和科學興趣小組的同學一道,利用兩個暑假時間,采取問卷調查、實地考察、檢測土壤和水質的科學方法,從“螢火蟲數量——觀察點環境——觀察點土壤、植被和水質狀況”等方面進行考察,對家鄉螢火蟲狀況進行調查研究,并寫出了《荊江一帶螢火蟲現狀的調查與思考》調查報告,該報告在第32屆湖北省青少年科技創新大賽中獲得創新項目一等獎。

    報告中指出,田野、溝渠、河流、樹林里的螢火蟲越來越少了。一個鄉鎮僅1-2個地方有螢火蟲,并且數量也不多。甚至有的鄉鎮幾乎找不到螢火蟲的蹤影了,“如果這樣下去,再過幾年螢火蟲就要絕跡了”。螢火蟲為什么會越來越少?他們的研究認為,螢火蟲數量減少是農村大量使用農藥和化肥造成的。為此,章夢妍等學生建議農民種地要盡可能少用農藥、化肥,特別是稻田、溝渠、田界、樹林是螢火蟲的棲息地,也是螢火蟲繁殖的地方,不能使用農藥和除草劑。

    近年來,監利縣教育局十分重視開發鄉土教育資源,利用農業生產、生態環境和昆蟲、植物等鄉村資源開展了一系列科普活動,“讓螢火蟲回到我們的身邊”是其中之一。他們以“戶外探索+科普”的形式引導青少年關注身邊的科學,對真實的科學問題進行調查和探究,從而激發學生科學興趣,培養科學思維,提升創新意識和解決問題的能力,把對科學的興趣轉變為志趣。
