    初中生周記-奇妙的科學之旅

    發布時間:2019-05-14 09:14 編輯:涪陽小學亞瑟老師

       寒假期間,我爸爸所在的浙江工業大學理學院對外開放了國家一級物理教學實驗室示范中心。我在父親的帶領下來到了實驗室。

      剛進門,我暗想:“這里會是一個什么樣的地方呢?會比浙江省科技館和上海科技館有趣嗎?”帶著疑問,我走進了實驗室。很快,燈亮了,一條十米的走廊瞬間變成了一條田園小路,周圍有樹木有小鳥有行人,真是個鳥語花香的好地方,時而傳來了幾聲鳥叫。我迫不及待地去抓那只鳥,一摸,卻是一堵冰冷的墻。什么?不會吧?原來只是幻象啊!接著,實驗室的徐老師也說道:“其實啊,是由一面面小鏡子片粘在燈管上。燈旋轉,投影機工作,放射出景象,再由小鏡面反射到墻上。”真是太神奇了!

      然后映入眼簾是彈球臺。由7個鋼球組成,拉動一個外球,側面的球也會分開。剛好對稱,徐老師一邊演示,一邊問道:“這是為什么?”我陷入了思考的泥潭,怎么也拔不出來。徐老師見我答不出來,便報答案了:“這是磁場效應,一個鋼球與其他鋼球相撞,帶動了鋼球運動,使得球對應且對稱。”我還沒聽明白。于是徐老師又重新講了一遍,頓時我恍然大悟,被徐老師從泥潭里拔出來。

      在這個實驗室里還有許多奇形怪狀的,功能獨特的儀器,都很有趣哦!
