hes (chemical → light + thermal), and simple pendulums. Narrate each energy pathway aloud.
利用玩具探究能量储存与转移：发条汽车（弹性势能 → 动能）、电池驱动的手电筒（化学能 → 光能 + 热能）、以及简单的钟摆。大声说出每一能量转换路径。
6. Developing Scientific Enquiry and Experiment Skills | 培养科学探究与实验技能
Teach your child to identify the independent, dependent, and control variables in any investigation. For example, in a test of how temperature affects sugar dissolving, temperature is the independent variable.
教会孩子识别任何探究活动中的自变量、因变量和控制变量。例如，在检验温度对蔗糖溶解影响的实验中，温度是自变量。
Practise drawing line graphs on grid paper. Emphasise labelling axes with quantities and units, choosing a sensible scale, and plotting points accurately. Discuss what the slope of the line tells you.
练习在方格纸上绘制折线图。强调用物理量和单位标注坐标轴、选取合适的比例、并精确描点。讨论斜率所代表的含义。
After an experiment, help your child write a conclusion that refers back to the hypothesis and uses data to support or reject it. Then evaluate reliability: were there any anomalies? How could the method be improved?
实验完成后，帮助孩子撰写结论，回扣假设并用数据支持或否定它。接着进行可靠性评估：是否存在异常数据？实验方法可以如何改进？
7. Effective Revision and Memory Techniques | 高效的复习与记忆技巧
Create a set of flashcards covering key definitions: terms like osmosis, catalyst, alkali, moment, and refraction. Use the Leitner system (sorting cards by how well they are known) for spaced repetition.
制作一套涵盖关键定义的闪卡：诸如渗透作用、催化剂、碱、力矩和折射等术语。运用莱特纳系统（按熟悉程度分类卡片）进行间隔重复记忆。
