开阳县第六小学三年级(四)班刘玲

有一天，科学老师给我们布置了一项家庭作业，是回家做一实验，观察水、油和洗涤精这三种液体，那一种的流得快，那种流得慢。

One day, the science teacher gave us a homework assignment, which is to go home and do an experiment to observe the three kinds of liquids: water, oil and detergent. One kind of liquid flows fast, the other kind flows slowly.

回家后，我就把三种液体准备好，用同样的三个杯子分别装进水、油和洗洁精，而且高度都相同。我先拿一个装有水的杯子，然后用针刺一个小洞并用手堵上;我请爸爸拿一个装上食用油的杯，然后用针刺一个小洞并用手堵上;我妈妈拿一个装有洗洁精杯子，然后用针刺一个小洞并用手堵上。我就叫一、二、三同时放开，来看哪种液体流得快。

When I get home, I'll prepare three kinds of liquid, and use the same three cups to fill water, oil and detergent respectively, and the height is the same. First, I take a cup with water, then I prick a small hole and close it with my hand; I ask my father to take a cup with edible oil, then I prick a small hole and close it with my hand; my mother takes a cup with detergent, then I prick a small hole and close it with her hand. I told one, two and three to let go at the same time to see which liquid flowed fast.

实验的结果是我发现：水流得最快，油流得较快，洗洁精流得最慢。

The result of the experiment is that I found that the water flow is the fastest, the oil flow is faster, and the detergent flow is the slowest.
