📚 Year 7 SQA Science: Essential Vocabulary Quick-Memorisation Guide | Year 7 SQA 科学：核心词汇速记指南
Mastering science vocabulary is the first step to understanding how the world works. This guide helps Year 7 SQA students quickly memorise key scientific terms using simple memory tricks – from word roots to vivid analogies.
掌握科学词汇是理解世界如何运作的第一步。本指南帮助Year 7 SQA学生通过简单的记忆技巧——从词根到生动的类比——快速记住关键科学术语。
1. The Scientific Method | 科学方法
Every investigation begins with a question. Learn these core terms to talk like a scientist.
每个探究都从一个问题开始。学习这些核心术语，像科学家一样说话。
Hypothesis – a testable prediction. Think of 'hypo' (under) and 'thesis' (idea). Imagine you have an idea hidden under a box, waiting to be tested. Write it as 'If... then...' to make it clear.
假设 – 可检验的预测。联想 'hypo'（在...下）和 'thesis'（论点）。想象你把一个观点藏在盒子下，等着去检验。用"如果...那么..."的句式来表达会更清晰。
Variable – any factor that can change. Remember the word 'vary'. In a fair test, you change only the independent variable and measure the dependent variable. Imagine you are a variable magician: you can change one thing at a time.
变量 – 任何可以改变的因素。记住 'vary'（变化）这个词。在公平实验中，你只改变自变量，并测量因变量。想象你是一个变量魔术师：每次只能变一个东西。
Fair test – an experiment where only one factor is changed. All other conditions must stay the same. Think of a race where everyone wears the same shoes except one person – that is fair for testing shoes.
公平测试 – 只有一个因素被改变的实验。其他所有条件必须保持不变。想象一场比赛，所有人都穿相同的鞋，只有一人不同——这就公平地测试了鞋子的影响。
Observation – using your senses or instruments to gather information. Say 'ob-serve' – you serve your attention to see details. Good observations are factual, not opinions.
观察 – 用你的感官或仪器收集信息。说 'ob-serve' – 你提供（serve）注意力去查看细节。好的观察是事实，而不是观点。
Conclusion – a summary stating whether your results support the hypothesis. It 'concludes' the story. Remember: it does not prove, it supports.
结论 – 总结你的结果是否支持假设。它'结束'了实验的故事。记住：结论不是证明，而是支持或否定假设。
2. Cells and Life Processes | 细胞与生命活动
All living things are made of cells. These terms build your biology foundation.
所有生物都由细胞构成。这些术语为你的生物学打下基础。
Cell membrane – the thin skin around a cell, controlling what enters and leaves. Think of it as a 'cell gate-keeper' or a border guard with a clipboard.
细胞膜 – 细胞周围的一层薄膜，控制物质的进出。把它想象成'细胞守门员'，或拿着登记板的边境警卫。
Nucleus – the control centre of the cell containing DNA. The word sounds like 'new-cle-us'. Imagine a new, clue-filled boss who holds all instructions. It is the brain of the cell.
细胞核 – 含有DNA的细胞控制中心。发音类似'纽扣里阿斯'。想象里面有个装满线索 (clue) 的新老板，手握所有指令。它是细胞的大脑。
Cytoplasm – the jelly-like substance where chemical reactions occur. Think 'cyto' (cell) + 'plasm' (fluid). It is the factory floor where work happens.
细胞质 – 发生化学反应的果冻状物质。'cyto'（细胞）+ 'plasm'（液体）。它是细胞里的工作车间地面。
Chloroplast – a green structure in plant cells that absorbs light for photosynthesis. Contains chlorophyll. Memory: 'chloro' sounds like 'chlorophyll
