1. Welcome to Year 8 Science | 欢迎来到 Year 8 科学
Year 8 Cambridge Science builds on the three disciplinary strands of biology, chemistry and physics, while weaving in essential scientific enquiry skills. You will begin to explore more abstract ideas such as chemical reactions, energy transfer and the interdependence of living things. The summer preview course ensures you are not just remembering facts, but truly understanding the 'how' and 'why' behind each phenomenon.
Year 8 剑桥科学在生物学、化学和物理学三条学科主线上继续深化，并同时融入了重要的科学探究技能。你将开始探索更抽象的概念，如化学反应、能量传递以及生物之间的相互依存关系。暑期预习课程确保你不仅仅是在记忆事实，而是真正理解每个现象背后的‘如何’与‘为何’。
The bridging approach revisits the most important ideas from Year 7, such as cells, particles and forces, and then gently extends them into Year 8 territory. This helps to close any lingering gaps and gives you the language and confidence to tackle new topics right from the first lesson in September.
衔接式学习会重温 Year 7 中最重要的概念，比如细胞、粒子和力，然后平缓地将它们延伸到 Year 8 的范畴。这有助于弥补任何遗留的知识空缺，并让你掌握语言工具和信心，能够在九月第一堂课上就顺利投入新课题。
2. Why a Bridging Course Matters | 衔接课程为何重要
Without a summer refresher, students often experience a 'learning slide' where key skills fade. A bridging course reactivates prior knowledge and frames it within the Year 8 context. Instead of spending the first few weeks of school catching up, you arrive already familiar with the core vocabulary and scientific models that will be used every day.
没有暑期的回顾，学生们常常会经历“学习滑坡”，关键技能逐渐生疏。衔接课程重新激活已有知识，并将其置于 Year 8 的背景之中。这样，你不用在开学的头几周忙于追赶，而是已经熟悉了每天都会用到的核心词汇和科学模型。
Moreover, the course develops independent learning habits. You learn to read scientific texts actively, ask investigative questions and connect different topics. These are exactly the skills assessed in the Cambridge Checkpoint and beyond, making the bridging experience a real academic advantage.
此外，衔接课程还能培养独立学习的习惯。你将学会主动阅读科学文本，提出探究性问题，并将不同主题联系起来。这些正是在剑桥 Checkpoint 乃至更高阶段考核的关键能力，让衔接体验成为真正的学术优势。
3. Key Skills from Year 7 | Year 7 的关键技能回顾
Before diving into new content, it is essential to refresh the core practical and thinking skills. In Year 7 you learned to identify variables (independent, dependent and control), record observations and draw simple conclusions. The bridging course puts these skills back at your fingertips through quick, focused activities.
在进入新内容之前，复习核心的实践与思维技能非常重要。在 Year 7 你学会了识别变量（自变量、因变量和控制变量），记录观察结果并得出简单的结论。衔接课程通过简短且有针对性的活动，让你重新熟练运用这些技能。
You also practised using scientific apparatus safely and taking accurate measurements with units such as grams, centimetres and degrees Celsius. We will revisit these measurement skills and link them to new Year 8 experiments, so that practical work feels natural rather than unfamiliar.
你还练习了安全使用科学仪器，并用克、厘米、摄氏度等单位进行准确测量。我们会重温这些测量技能，并将它们与 Year 8 的新实验联系起来，让实践操作变得自然顺手，而不至于生疏。
