📚 Year 7 WJEC Science: Summer Preparation and Bridging Course | 7年级WJEC科学：暑期预习与衔接课程
Transitioning from primary to secondary school science can be both exciting and challenging. The WJEC Year 7 science course builds on your curiosity about the world and introduces more structured scientific thinking. This summer bridging guide will help you get a head start by exploring key topics, practical skills, and study strategies so that you feel confident and ready for the year ahead.
从小学升入中学，科学课既令人兴奋又充满挑战。WJEC 7年级科学课程以你对世界的好奇心为基础，引入更系统的科学思维。这份暑期衔接指南将帮助你抢先一步，探索关键主题、实验技能和学习策略，让你信心满满地迎接新学年。
1. Why Summer Bridging Matters for Year 7 Science | 为什么暑期衔接对7年级科学至关重要
Starting Year 7 science with a solid foundation can reduce anxiety and improve long-term performance. A summer bridging course allows you to revise primary-level concepts and gently introduce new secondary-level ideas like cells, particles, and forces. By spending just a little time each week, you can develop the scientific vocabulary and thinking habits that teachers expect.
带着扎实的基础开始7年级科学学习，可以减轻焦虑并提升长期表现。暑期衔接课程让你复习小学阶段的概念，并温和地引入细胞、粒子和力等中学新知识。每周只需花一点时间，你就能建立起老师期望的科学词汇和思维习惯。
Many students find the jump in terminology and abstract thinking difficult. Bridging work helps you become familiar with key terms such as 'hypothesis', 'variable', and 'organism' before you encounter them in class, so you can focus on understanding rather than memorising.
许多学生觉得术语和抽象思维的跳跃很困难。衔接学习帮助你在课堂上遇到诸如“假设”、“变量”和“生物体”等关键术语之前就熟悉它们，这样你就可以专注于理解而非死记硬背。
2. An Overview of the WJEC Year 7 Science Curriculum | WJEC 7年级科学课程概述
The WJEC Year 7 science syllabus covers three main subject areas: Biology, Chemistry, and Physics, all woven together with 'Working Scientifically' skills. You will explore living organisms, materials and their properties, and energy and forces, alongside learning how to plan and carry out investigations.
WJEC 7年级科学课程大纲涵盖三大领域：生物学、化学和物理学，同时融入“像科学家一样工作”的技能。你将探索生物体、材料及其性质，以及能量和力，同时学习如何规划和开展探究。
Key topics include cells and reproduction, classification of living things, states of matter, simple chemical reactions, forces and motion, and electrical circuits. You will also be assessed on your practical skills, such as using a microscope, measuring temperature, and recording data in tables.
关键主题包括细胞与生殖、生物分类、物质状态、简单的化学反应、力与运动以及电路。你还将接受实验技能的评估，如使用显微镜、测量温度和在表格中记录数据。
3. Scientific Enquiry: Asking Questions and Designing Investigations | 科学探究：提出问题与设计调查
At the heart of WJEC science is 'Working Scientifically'. This means you will learn to ask testable questions, form hypotheses, identify variables, and design fair tests. For example, if you wonder 'Does temperature affect how fast sugar dissolves?', you are already thinking like a scientist.
WJEC科学的核心是“像科学家一样工作”。这意味着你将学习提出可检验的问题、形成假设、识别变量并设计公平测试。例如，如果你想知道“温度会影响糖溶解的速度吗？”，你就已经在像科学家一样思考了。
Understanding independent, dependent, and control variables is crucial. In the sugar experiment, the temperature of the water is the independent variable (what you change), the time taken for sugar to dissolve is the dependent variable (what you measure), and the amount of water, type of sugar, and stirring speed are control variables (what you keep the same).
理解自变量、因变量和控制变量至关重要。在糖的实验中，水的温度是自变量（你改变的），糖溶解所需的时间是因变量（你测量的），而水量、糖的种类和搅拌速度是控制变量（你保持不变的）。
4. Biology Basics: Living Organisms and Cells | 生物学基础：生物体与细胞
One of the first topics you will study in Year 7 biology is cells—the building blocks of life. You will learn to use a light microscope to view plant and animal cells, and you will label structures such as the nucleus, cytoplasm, cell membrane, and cell wall. Remember, plant cells have chloroplasts and a permanent vacuole, which animal cells lack.
在7年级生物学中，你首先学习的主题之一是细胞——生命的构建块。你将学习使用光学显微镜观察植物和动物细胞，并标注细胞核、细胞质、细胞膜和细胞壁等结构。记住，植物细胞有叶绿体和一个大液泡，而动物细胞没有。
You will also explore the seven life processes often remembered by the acronym MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. All living organisms, from bacteria to blue whales, carry out these processes.
你还将探索七个生命过程，通常用首字母缩写 MRS GREN 来记忆：运动、呼吸、敏感性、生长、繁殖、排泄和营养。所有生物体，从细菌到蓝鲸，都进行这些过程。
5. Biology: Ecosystems and Adaptation | 生物学：生态系统与适应性
Understanding how organisms interact with their environment is a key part of WJEC Year 7 science. You will study food chains and food webs, learning how energy is transferred from producers (plants) to consumers (animals) and decomposers.
了解生物如何与环境相互作用是WJEC 7年级科学的关键部分。你将学习食物链和食物网，了解能量如何从生产者（植物）转移到消费者（动物）和分解者。
You will also explore how organisms are adapted to their habitats, such as the thick fur of a polar bear or the long roots of a desert cactus. Adaptations can be structural, behavioural, or functional, helping organisms survive and reproduce.
你还将探索生物如何适应其栖息地，例如北极熊的厚皮毛或沙漠仙人掌的长根。适应性可以是结构上的、行为上的或功能上的，帮助生物体生存和繁殖。
6. Chemistry: Particles and States of Matter | 化学：粒子与物质状态
In chemistry, you will be introduced to the particle model to explain solids, liquids, and gases. All matter is made of tiny particles that are constantly moving. In solids, particles are tightly packed in a regular pattern and only vibrate; in liquids, they are close together but can slide past each other; in gases, they are far apart and move
