小學滿分作文:神奇的乒乓球
在作文寫作中,一件事情的發生,離不開時間、地點、人物、事情的起因、經過和結果這六方面,即常說的“六要素”,只有交待清楚這幾方面,才能使讀者對所敘述的事,有個清楚、全面的了解。
從作文的寫作命題來分,作文可以分為命題作文和非命題作文。命題作文,一般是指出題者給出一個既定的題目,要求應試者根據這個給定題目進行寫作。
今天小編要與大家分享的是:小學滿分作文:神奇的乒乓球,具體內容如下,僅供閱讀參考。
神奇的乒乓球
今天,我正對著墻打乒乓球時,一不小心把乒乓球給踩扁了。正當我不知所措時,爸爸走過來了。爸爸似乎看懂了我的心思,便拿著乒乓球對我說:“溪溪,我們來做一個實驗吧!”我一口就答應了。
爸爸燒了一壺開水,便把乒乓球放了進去,我眼也不眨的盯著乒乓球。只見被我踩扁的乒乓球漸漸的鼓了起來,不一會兒,乒乓球又變成圓圓的了。我覺得這太神奇了,便連忙問爸爸這是怎么回事。爸爸說:“這是熱脹冷縮的緣故。”“那什么是熱脹冷縮呢?”我急忙問。爸爸說:“熱脹冷縮就是一個物體在遇到高溫的情況下,那個物體就會膨脹。例如現在我們做的這個實驗。反之,如果一個物體在遇到低溫的情況下,那個物體就會縮小。例如冬天天氣冷時,我們是不是都縮成一團?”說完,爸爸和我都笑了。
聽完爸爸的話,我想,原來在我們的生活中也離不開科學呀!只要你在生活中認真傾聽、在生活中仔細觀察,在生活中靜靜思考,你會發現科學就在我們的身邊!
