磁极
Magnetic Poles
将磁铁描述为具有两个磁极(北极和南极),并根据两个磁铁相对的磁极来预测它们是相互吸引还是相互排斥。
Describe magnets as having two poles (north and south) and predict whether two magnets will attract or repel based on which poles face each other
学习证据 / Evidence
- 识别并标出磁铁的南极和北极。
- 说出“同极相斥,异极相吸”的规律。
- 根据两块磁铁相对的磁极,预测将它们靠近时会有什么结果。
- Identify and label the north and south poles of a magnet
- State the rule: like poles repel, opposite poles attract
- Predict the outcome of bringing two magnets together based on their pole orientation
