📚 Year 7 Edexcel Science: Case Study Practical Exercises | 七年级Edexcel科学：案例分析实战演练

In Year 7 Edexcel Science, working scientifically is a core skill. You will often be given a case study where you must plan an investigation, collect data, and evaluate results. This article is a practical walkthrough of a common case study: investigating which material keeps a hot drink warm for longest. By following each step, you will strengthen your understanding of variables, fair testing, graphing, and scientific conclusions – all essential for your exams.

在七年级爱德思科学中，“科学地工作”是一项核心技能。你经常会遇到案例研究，需要规划调查、收集数据和评估结果。本文是对一个常见案例的实战演练：探究哪种材料能让热饮保温最久。通过逐步推进，你将加深对变量、公平测试、图表绘制和科学结论的理解——这些对考试至关重要。

1. Understanding the Case Study Scenario | 理解案例情景

Your teacher gives you four identical beakers, each filled with 200 cm³ of hot water at 80 °C. Each beaker is wrapped in a different material: cotton wool, aluminium foil, newspaper, and bubble wrap. Your aim is to determine which material is the best insulator – the one that reduces heat loss to the surroundings most effectively.

老师给你四个相同的烧杯，每个装有200 cm³ 80 °C的热水。每个烧杯分别包裹不同的材料：棉絮、铝箔、报纸和气泡膜。你的目标是确定哪种材料是最好的隔热体——它能最有效地减少向周围环境的热量散失。

You must think like a scientist: What are you changing? What will you measure
