苏科版八年级物理“直线运动”一节中的学生实验“探究水管中气泡的运动规律”是研究匀速直线运动特点非常理想的教学资源。由于该实验器材不常见、气泡经过的路程短等原因,导致实验存在一些不足。为此,可利用常见的实验器材对教材实验方案进行创新改进,用PVC塑料管代替玻璃管,适当增加管子的长度,竖直放置水管。这样就可以更好地完成探究实验。
The “Student’s Experiment in the section of Physics in the eighth grade of Physics and the ”straight motion“ section of the Suko edition ”Exploring the movement law of bubbles in water pipes" is a very ideal teaching resource for studying the characteristics of uniform linear motion. Due to the unusualness of the experimental equipment and the short distance traveled by the bubbles, there are some deficiencies in the experiment. For this purpose, the experimental programs of the teaching materials can be innovatively improved by using common experimental equipment. PVC plastic tubes are used instead of glass tubes, and the length of the tubes is appropriately increased to vertically place the water tubes. This will better complete the inquiry experiment.
