弘科未来小学部丨IB学习者养成记：一滴水里的可持续发展课

同学们首先参观了水厂沙盘模型。立体的模型直观展示了水循环过程，通过触摸操作，孩子们逐步理解水处理的基本原理。

在模拟水质净化的小游戏中，学生们亲自动手体验过滤杂质的过程。当看到砂石被滤网拦截时，他们开始理解清洁水源的重要性。

通过这样寓教于乐的方式，孩子们在游戏互动中建立起"保护水资源就是保护生态环境"的朴素认知。

在大丰水厂取水口，小学部的同学们认真聆听了工作人员讲解水源地保护知识。

当了解到全球20亿人面临饮水困难时，懂得关爱的学生们立即讨论起节水方法：有人建议用淘米水浇花，有人提出缩短洗澡时间。这些稚嫩但真诚的对话中，我们看到了他们坚持原则的节水决心，以及作为胸襟开阔的小公民对世界问题的关注。

随后，同学们实地观察水处理全流程，依次了解沉淀、过滤、消毒三大核心环节，直观理解SDG12（负责任消费和生产）的目标内涵。

在分组进行的过滤实验中，他们用活性炭、石英砂等材料搭建简易净水装置。当浑浊的水逐渐变清澈时，孩子们展现出“积极探究”的学习态度，细致记录着每层滤料对水质的改善效果。实验过程中，“勇于尝试”的IB学习者特质得到了充分体现，不少组别主动调整滤材配比以优化净化效果。

参观完净化流程后，又跟着水厂工作人员来到了制水工艺区域。这里摆放着各种复杂的制水设备。

在这里了解到，每一滴水要变成能喝的自来水，需要经过很多道工序。同学们还参与了检测水质的活动。当pH试纸在指尖慢慢变色，余氯检测仪的数字跳动时，他们不仅发现了化学的有趣之处，还感受到了可持续发展的实际意义。

活动最后，同学们开展了“疏水大作战”游戏。这个模拟荷叶疏水特性的实验，要求团队合作搭建防水装置。

当看到水流在特制材料表面形成滚珠状时，他们分组讨论起莲叶效应在雨衣设计中的应用可能。

这种将物理探索与生态保护结合的体验，让“团队合作”的价值在装置调试中自然显现——有的小组负责材料测试，有的专注结构改良，最终共同完成疏水效能提升。

The exploration began with interactive 3D hydrological models demonstrating urban water cycles. Through tactile sandbox simulations and water filtration games using layered filtration systems, students physically experienced sediment retention processes. Observing trapped particles in filter meshes sparked their first conceptual understanding: "Water conservation equals ecological preservation" - a fundamental SDG principle materializing through play-based learning.

At the plant's raw water intake, technicians explained watershed protection challenges.

Learning that 2 billion people face water scarcity worldwide, these principled young minds immediately brainstormed conservation strategies - from reusing rice-washing water for plants to reducing shower durations. Their earnest dialogue revealed developing attributes of open-mindedness and global awareness, transforming abstract SDG concepts into actionable commitments.

The treatment process tour became a live demonstration of SDG12 (Responsible Consumption and Production). Students observed flocculation basins, rapid sand filters, and ozone disinfection systems before constructing miniature purification towers using activated carbon and quartz sand.

As turbid water clarified through their multilayer filters, detailed observation records showcased inquiry skills, while iterative filter media adjustments demonstrated risk-taking - both essential IB learner attributes in action.

In the analytical laboratory, digital pH meters and chlorine residual testers transformed students into water chemists. Watching test strips change color and digital readouts fluctuate, they discovered the concrete science behind SDG implementation. This hands-on experience with titration and turbidity measurement revealed how chemical monitoring translates to sustainable development practice.

The program culminated in a lotus effect experiment mimicking natural water repellency.

Collaborative teams engineered hydrophobic surfaces using biomimetic materials, discussing potential applications in eco-friendly rainwear.

Through prototype testing and structural optimization, students naturally demonstrated IB's collaborative principle - some groups focused on material selection while others perfected angles of inclination, collectively enhancing water runoff efficiency.
