Chunking: Group similar words together. Study all separation techniques (filtration, distillation, chromatography) in one sitting, then test yourself by drawing a mind map.

组块法：把相似词汇归组。一次学习所有分离技术（过滤、蒸馏、色谱法），然后通过画思维导图自测。

Word origins: Many chemistry terms have Latin or Greek roots. ‘Hydro’ = water; ‘chlor’ = green; ‘photo’ = light. Spotting these roots makes longer words less intimidating.

词源：许多化学术语有拉丁或希腊词根。’Hydro’ = 水；’chlor’ = 绿；’photo’ = 光。认出这些词根可以让长单词不那么吓人。

Teach someone: The best way to confirm you know a term is to explain it to a friend or even your pet. Articulating a definition aloud cements it in memory.

教给别人：确认你掌握一个术语的最好方式是向朋友甚至宠物解释它。大声说出定义，会将它固定在记忆中。

Flashcards with a twist: On one side write the term, on the other a silly picture or mnemonic, not just the definition. The surprise element makes recall faster.

趣味闪卡：一面写术语，另一面画个滑稽图画或写下助记法，而不只是定义。意外元素让回忆更快。
