      讓學生分分鐘愛上科學,牛津國際公學趣味實驗集錦!
      發表時間:2019-04-22   瀏覽次數:782次



      科學小實驗,兼顧了科學性與趣味性,能夠有效調動學生探索世界的興趣。對科學的愛好,對事物原理的探究精神,就是在這樣的親手實踐中培養出來的。通過各類實驗與觀察,去獲得最初的、第一手的、感官的認識,是牛津國際公學倡導的教學理念。

       

      與普通中學相比,牛津國際公學理化生課程,會花更多精力和時間在實踐課上,學生能夠在做實驗的過程中更深刻理解理論知識,動手能力也可以得到充分培養。每次實驗課,老師也會指導學生完成實驗報告,并給出個性化反饋。

       

      除了實驗課程,牛津國際公學還會組織學生去參觀生命的奧秘博物館、成都植物園等科普基地,讓學生在玩中學習,加深對知識的理解。

       

      維生素含量對小白鼠成長的影響

       

      這是由12年級的Christina同學牽頭,和其他幾位同學自主研究的實驗。他們每天都會給小白鼠稱重,觀察不同濃度的維生素含量對小白鼠成長的影響。這個實驗目前持續了四天,同學們還將繼續記錄小白鼠的生長情況。

       

       

       

       

       

       

       抑制大腸桿菌存活率

       

      實驗原理:

      抗生素能破壞細菌細胞壁的結構,使細菌的繁殖和生長受到抑制。但某些細菌對抗生素表現出抗性,原因是其基因發生了改變,產生能抵抗抗生素的性狀。

      菌種:大腸桿菌

      儀器:超凈臺、離心機、高壓滅菌鍋、培養箱、磁力攪拌器、培養皿、涂布器、移液管、移液器

       

       

      (對于大腸桿菌,同學們“殺”起來毫不手軟)

       

       

      幾天后的實驗結果與分析報告,等著同學們去完成

       

       

       有趣的“大象牙膏”實驗

       

       https://v.qq.com/x/page/v0862zg7trs.html

      (視頻鏈接)

       

      聽見同學們的笑聲,就知道這是一個非常有趣的實驗

       

       

      原料:雙氧水 +酵母(高錳酸鉀或碘化鉀)+洗潔精 +色素

       

      步驟:按照一定的比例和順序放在類似于可樂瓶的細口容器中進行混合,即可觀察到一股充滿氧氣的泡沫狀物質像噴泉一樣從容器中噴涌而出,這就叫做大象牙膏實驗。

       

      原理:雙氧水在酵母的催化作用下,生成水和氧氣,在生成氧氣之后遇到容器中的發泡劑,于是就產生了實驗效果。

       

       

      判斷分子的極性

       

       https://v.qq.com/x/page/f0862qtzmzs.html


      (視頻鏈接)

       

      原理:筆通過摩擦起電,帶有電荷。有極性的液體,會受到電荷的吸引,從而改變流動的姿態。

       

       

      制作分子模型

       

      為了加深同學們對各種化學分子結構的認識,Nate 老師讓10年級同學們用輕質黏土做出各類分子結構模型。
