📚 Year 7 CCEA Science: Vocabulary & Terminology Quick Memorisation Guide | Year 7 CCEA 科学：词汇术语速记指南

Mastering scientific vocabulary is the secret to success in Year 7 CCEA Science. This guide breaks down essential terms into bite-sized chunks with clever memory hooks, helping you understand and recall key concepts for experiments, biology, chemistry, physics and Earth science.

掌握科学词汇是 Year 7 CCEA 科学取得成功的秘诀。本指南将基本术语拆解成小块，并配有巧妙的记忆钩子，帮助你理解和回忆实验、生物、化学、物理和地球科学中的关键概念。

1. Scientific Inquiry Terms | 科学探究术语

Hypothesis – An educated guess or prediction that can be tested. It is the idea you are investigating. Think of ‘hypo’ (under) and ‘thesis’ (a placing) – the idea placed under examination.

假设 – 一种可以被检验的有根据的猜测或预测。它是你正在研究的想法。联想 ‘hypo’（在下面）和 ‘thesis’（放置）——放在检验之下的想法。

Independent variable – The factor you deliberately change in an experiment. ‘I change the Independent variable’ is a quick way to remember it.

自变量 – 你在实验中故意改变的那个因素。’I change the Independent variable’（我改变自变量）是记忆它的快捷方式。

Dependent variable – The factor you measure or observe; its value depends on the change you made. Picture it as the data that ‘depends’ on your action.

因变量 – 你测量或观察的因素；它的值取决（依赖）于你所做的改变。把它想象成 ‘取决于’ 你行动的数据。

Control variables – All the other factors that must be kept the same to make the test fair. ‘Control = keep constant’.

控制变量 – 所有其他必须保持相同的因素，以确保测试公平。’Control = 保持不变’。

Fair test – An experiment where only the independent variable is changed, so you can be sure it causes the effect. Imagine a race where everyone except one runner gets the same type of shoes.

公平测试 – 只有自变量被改变的实验，这样你才能确定是它引起了效应。想象一场比赛，除了一个选手外，其他人的鞋子都一样。

Conclusion – A summary that states what you found out and whether it supports your hypothesis. Link it back to your prediction.

结论 – 一份总结，说明你的发现以及其是否支持假设。要将其与你的预测联系起来。

2. Cells and Life Processes | 细胞与生命过程

Cell – The smallest unit of life. Think of it as a tiny room (‘cell’ like a prison cell) where all life processes happen. Plants and animals are made of cells.

细胞 – 生命的最小单位。把它想象成一个微小的房间（’cell’ 如同牢房），所有生命过程都在其中进行。植物和动物都由细胞组成。

Cell membrane – The thin skin around a cell that controls what enters and leaves. ‘Membrane’ sounds like ‘membrane filter’ – it filters traffic in and out.

细胞膜 – 包裹细胞的薄膜，控制物质进出。’Membrane’ 听起来像 ‘膜过滤器’——它过滤进出的物质流。

Nucleus – The control centre of the cell that contains genetic material (DNA). ‘Nucleus’ = core, like the nucleus of a command centre.

细胞核 – 细胞的控制中心，含有遗传物质 (DNA)。’Nucleus’ = 核心，就像指挥中心的核心。

Cytoplasm – The jelly-like substance filling the cell where chemical reactions take place. ‘Cyto’ means cell, ‘plasm’ means stuff.

细胞质 – 充满细胞的胶状物质，化学反应在此发生。’Cyto’ 表示细胞，’plasm’ 表示浆质。

Respiration – The process that releases energy from food in all living cells. Do not confuse it with breathing (ventilation). ‘Respiration = releasing energy, re-sparking the body’.

呼吸作用 – 在活细胞中从食物释放能量的过程。不要与呼吸（通气）混淆。’Respiration = 释放能量，为身体重新点火’。

Photosynthesis –
