八年级下册科学错题及解析第一单元
八年级下册科学错题及解析第一单元一、错题11. 题目：在探究“压力的作用效果与哪些因素有关”的实验中，某同学做了如图所示的三个实验。
（1）比较甲、乙两图可知：压力一定时，______。
（2）比较乙、丙两图可知：______相同时，压力越大，压力的作用效果越明显。
（3）该实验中用到的研究方法有______和______。
2. 错误答案：（1）受力面积越小，压力的作用效果越明显。
有同学写成“压力越小，压力的作用效果越明显”，这是完全错误的概念。
说白了，在这个实验里，我们是控制压力不变，去看受力面积的变化对压力作用效果的影响，而压力变小这个结论与实验事实相悖。
（2）受力面积。
有的同学写成“压力”，这是没有认真分析实验变量。
话说回来，乙、丙两图中是受力面积相同，压力不同，所以是受力面积相同时，压力越大，压力的作用效果越明显。
（3）控制变量法和转换法。
有同学只写了一种方法，或者写成了类比法之类的错误方法。
其实，我们在研究压力作用效果与多个因素的关系时，控制其中一个因素不变，研究另外因素的影响，这就是控制变量法；而通过观察海绵的凹陷程度来反映压力的作用效果，这就是转换法。
二、错题21. 题目：液体压强的计算公式是p =ρgh，其中ρ表示液体的______，g是______，h是______。
2. 错误答案：ρ有的同学写成“质量”。
这可就大错特错了，ρ表示的是液体的密度。
密度和质量可是完全不同的概念，就像水和油，它们密度不同，在同样的容器里产生的压强也不同。
g有的同学写成“重力”。
其实g是一个常量，是重力加速度，约等于9.8N/kg。
对了，这个数值在很多与重力和质量相关的计算中都会用到，可不能和重力概念混淆。
h有的同学写成“深度”但是理解成了“高度”。
这里的h是指从液体表面到所求压强处的垂直距离，也就是深度。
如果理解成高度，那计算出来的压强就完全不对了。
三、错题31. 题目：阿基米德原理的内容是：浸在液体中的物体受到向上的浮力，浮力的大小等于______。
