做實驗作文350字

時間:2018-01-16來源:本站整理 編輯:xiaoya 點擊:

今天,我和媽媽出去玩,我看見一個人拿著放大鏡,在太陽底下照一張紙。那張紙白白凈凈的,上面一個字都沒有,那個人拿放大鏡在看什么呢?我很好奇,就站在那人旁邊看。過了一會兒,紙居然冒起了煙,接著就生起了一個火苗。“哇真神奇”我心里想。我覺得很有趣,便迫不及待地跑去買了一個放大鏡,也來做實驗。

我撿了一張紙巾,開始把放大鏡集來的光照到紙上。過了一會兒,紙卻沒有反應。我有些不耐煩了。一旁的媽媽看見了,笑著鼓勵我說:“做事不能半途而廢,既然想做,就要堅持到底。”我點點頭,繼續我的實驗。我把光點縮小了一點,用手指摸了一下紙上的光點,感覺很熱。我想:這下子應該有戲了。果然,不多久,紙巾燃起了火苗。我高興地大聲喊叫:“媽媽,媽媽,快看,快看,我成功了。”媽媽向我豎起了大拇指。我們都被成功的喜悅包圍著。

我覺得科學真神奇啊!
