由于学生们对于阿基米德原理总是只停留在机械的记住了实验的结论 F浮=G排,对于这个结论的得出过程始终没有清晰的印象,导致对于这个结论的理解深度不够,更不用说能灵活的应用它。所以理解好教材安排的实验“浮力的大小等于什么”非常重要。同学们通过实验,得出了F浮=G排,这个实验只反映了在水中会下沉的物体浸没在水中时受到的浮力等于它排开水受到的重力。这个结论是否也适用于漂浮的物体呢?利用上面的实验器材和一个会漂浮在水面的物体,你将怎样进行验证呢?
Since students always hold the conclusion of the experiment that the principle of Archimedes is always mechanical, there is no clear impression on the process of derivation of this conclusion, which leads to the insufficient understanding of this conclusion. Not to mention flexible application of it. Therefore, it is very important to understand the experiment arranged by the teaching materials and what is the size of buoyancy. Through experiments, the students reached the F = G row. This experiment only reflects the buoyancy of the object sinking in the water when immersed in water equal to the gravity of the water it drains. Does this conclusion also apply to floating objects? Using the above experimental equipment and an object that floats on the water, how can you verify it?
