And then, meterruler, ruler, andprotractor. Before experiment, fill the plastic bottles with water; use the same strength to squeeze the bottle. We need to ensure the strength is same in the whole experiment. 二、作出假设： 首先，我们推测，洞口越小，水的射程越远。其次，我们推测，在0°到90°之间，随着角度的增大，水的射程越远。最后，我们推测，水射程的远近，跟塑料瓶距离地面的高度无关。 Ⅱ.Make assumptions First of all, we speculate that the smaller the hole, the longer range of water. Second, we speculate that with the increase of angle, the range of the water will be longer. Finally, we speculate that range of water has nothing to do with the height of the plastic bottles from the ground. 三、进行试验，数据收集与整理： 首先，我们保持塑料瓶距离地面100cm，塑料瓶的倾斜角度为0°，分别用三个有不同大小圆洞的瓶盖，依次测量水的射程，来验证水的射程与瓶盖上洞大小的关系，进行比较。实验数据如下所示： Ⅲ.Do experiment, collect data and analyze data ⑴ First of all, we keep the plastic bottles from the ground 100 cm, plastic bottle angle for 0, respectively with three different size hole and, in turn, measuring the range of water, to test the relationship between range of the water with the hole size,The experimental data are shown below: 篇二：实验报告单摆的设计与研究 实验题目： 实验简介 单摆实验是个经典实验，许多著名的物理学家都对单摆实验进行过细致的研究。本实验的目的是学习进行简单设计性实验的基本方法，根据已知条件和测量精度的要求，学会应用误差均分原则选用适当的仪器和测量方法，学习累积放
