| AO1 Knowledge with understanding | 50% | 40% |
| AO2 Handling information and problem-solving | 30% | 35% |
| AO3 Experimental skills and investigations | 20% | 25% |
This rebalancing aligns with the global trend towards competency-based education, ensuring that students truly grasp the scientific process rather than merely recalling facts.
这种再平衡与全球倡导的能力本位教育趋势一致，确保学生真正掌握科学过程，而非仅仅回忆事实。
2. Greater Focus on Practical Skills | 更加注重实践技能
From 2026, the assessment of Year 7 practical work will extend beyond the final outcome to include planning, identifying variables, and suggesting improvements. Students will be expected to design simple investigations, such as how temperature affects the rate of dissolving, and write clear step-by-step methods incorporating safety precautions.
从2026年起，对Year 7实验工作的评估将超越最终结果，涵盖计划制定、变量识别和提出改进建议。学生需要设计简单的探究，例如温度如何影响溶解速率，并撰写包含安全预防措施的清晰分步方法。
Furthermore, greater emphasis will be placed on accurate measurement, appropriate choice of apparatus, and the concept of repeatability. Simple apparatus like thermometers, measuring cylinders, and Bunsen burners will remain central, but exam questions will probe how well students can justify their choices.
此外，将更加强调精确测量、仪器的恰当选择以及可重复性的概念。温度计、量筒和本生灯等简单仪器仍将是核心，但试题将探究学生能否为其选择给出合理依据。
3. Integration of Environmental Chemistry | 环境化学的整合
One of the most visible trends in the 2026 syllabus is the embedding of environmental topics within core chemistry. Students will explore acid rain formation, the carbon cycle, and the impact of plastics. They are expected to explain the underlying chemical processes, such as the reaction of sulfur dioxide with water to form acid rain, and debate sustainable alternatives.
2026年教学大纲最显著的趋势之一是将环境主题嵌入核心化学。学生将探索酸雨的形成、碳循环以及塑料的影响。他们需要解释背后的化学过程，例如二氧化硫与水反应形成酸雨，并讨论可持续的替代方案。

5. Emphasis on Particle Theory | 粒子理论的重点考查
Particle theory remains the bedrock of Year 7 Chemistry, but 2026 assessments will demand deeper application. Students will be asked to use particle diagrams to explain phenomena like why gases can be compressed, why diffusion is faster in hot water, and why balloon expands in sunlight.
粒子理论仍然是Year 7化学的基石，但2026年的评估将要求更深层次的应用。学生将被要求使用粒子图解释现象，例如为何气体可被压缩、为何热水中扩散更快，以及为何气球在阳光下膨胀。
Marks will be awarded for accurate depiction of particle motion, arrangement, and spacing, rather than simply stating the state of matter. The concept of energy transfer between particles during state changes will also be highlighted.
评分将侧重于准确描绘粒子的运动、排列和间距，而不仅仅是陈述物质状态。状态变化过程中粒子间能量转移的概念也将被强调。
6. New Topics in Acids and Alkalis | 酸与碱的新课题
While traditional indicator-based testing remains, the 2026 curriculum introduces a more quantitative approach to acids and alkalis. Students will learn to use the pH scale numerically, comparing strengths of acidic and alkaline solutions beyond simple colour changes. Everyday examples like citric acid in lemons, ethanoic acid in vinegar, and sodium hydrogencarbonate in baking powder will be integral.
虽然基于指示剂的传统测试依旧保留，但2026年的课程对酸和碱引入了更为量化的方法。学生将学习使用pH标度的数值，比较酸碱溶液的强度，而不仅限于颜色变化。日常实例，如柠檬中的柠檬酸、醋中的乙酸和小苏打中的碳酸氢钠，将成为重要内容。
Neutralisation word equations, such as hydrochloric acid + sodium hydroxide → sodium chloride + water (HCl + NaOH → NaCl + H₂O), will be introduced at this stage. Students should recognise the real-world applications, including antacid tablets for indigestion and lime treatment for acidic soils.
此时将引入中和反应的文字方程式，例如盐酸 + 氢氧化钠 → 氯化钠 + 水（HCl + NaOH → NaCl + H₂O）。学生应了解其实际应用，包括用于消化不良的抗酸片和针对酸性土壤的石灰处理。
7. Data Interpretation and Analysis | 数据解读与分析
Examination papers from 2026 will feature more complex data sets in the form of tables and graphs. Students will need to describe trends, identify anomalous results, and draw conclusions from solubility curves or temperature-time data during heating of a solid.
2026年的考试卷将出现更多以表格和图表形式呈现的复杂数据集。学生需要描述趋势、识别异常结果，并从溶解度曲线或固体加热过程中的温度-时间数据中得出结论。
For example, a question might present a table showing the mass of salt dissolved at different temperatures, and ask students to calculate the mean solubility, plot a graph, and predict the value at an intermediate temperature. Such tasks integrate mathematical skills with chemical understanding.

| Solute + liquid | Solute + solvent → solution |
| Air holes | Air vents / gas inlets |
| Turning into a gas | Evaporation / boiling |
Adopting accurate terminology early helps students communicate their ideas clearly and earns marks in explanation-based questions, which will be more prevalent in 2026 papers.
尽早采用准确术语有助于学生清晰表达想法，并在解释类题目中获得分数，这类题目在2026年的试卷中将更为常见。
9. Common Misconceptions to Avoid | 需要避免的常见误解
Several misconceptions have been identified that repeatedly cause students to lose marks. The 2026 assessments are designed to target these through carefully crafted multiple-choice distractors and structured questions.
已经识别出几个反复导致学生失分的误解。2026年的评估旨在通过精心设计的选择题干扰项和结构化问题来考查这些误解。
Misconception 1: ‘Particles expand when a substance is heated.’ Reality: The particles themselves do not increase in size; the space between them increases. In melting, the particle size remains the same, but the arrangement changes.
误解1：‘物质受热时粒子膨胀。’事实：粒子本身并不变大，而是粒子间的距离增加。熔化时粒子大小保持不变，但排列方式改变。
Misconception 2: ‘Mass disappears during burning because the substance gets lighter.’ Reality: Mass is conserved; gaseous products like carbon dioxide and water vapour escape into the air, so the measured mass of solids left behind decreases.
误解2：‘燃烧过程中质量消失了，因为物质变轻了。’事实：质量守恒；二氧化碳和水蒸气等气体产物逸散到空气中，因此留下的固体测量质量减少。
Misconception 3: ‘All acids are dangerous and corrosive.’ Reality: Many weak acids are found in foods and are safe to consume in moderation. Corrosiveness depends on concentration and chemical nature.
误解3：‘所有酸都是危险且具腐蚀性的。’事实：许多弱酸存在于食物中，适量摄入是安全的。腐蚀性取决于浓度和化学性质。
10. Preparation Strategies for 2026 | 2026年备考策略
To excel in the new assessment landscape, Year 7 students should adopt a proactive learning approach. First, engage actively in practical lessons—record observations meticulously and always ask ‘why’ something happened.
要在新的评估格局中脱颖而出，Year 7学生应采取主动的学习方法。首先，积极参与实验课——细致记录观察，并始终追问’为什么’会发生某种现象。
Second, create visual summaries such as mind maps that link concepts like particle theory, states of matter, and energy. Practice explaining everyday phenomena
