花园里一盆苗长得更高。是因为多浇水，还是恰好晒到更多太阳？One seedling grows taller. Was it extra water or simply more sunlight?
第 1 步：提出可检验的问题Step 1: Ask a testable question
先把猜想说得更明确。Make the proposed explanation precise.
科学研究用证据检验解释。假设是待检验的说法。“多浇水更好”还不够具体。说清水量、植物和时间，才更容易检验。Scientific inquiry tests explanations against evidence. A hypothesis is a claim to investigate. Specifying water amount, plant type and time makes “more water helps” easier to test.
第 2 步：比较并控制混杂Step 2: Compare and control confounding
怎样知道不是阳光造成的？How can sunlight be separated from watering?
让两组植物尽量具有相同光照和土壤，只改变设定水量。随机分组能减少系统差异。多株重复比只看一株更能识别偶然波动。Keep light and soil comparable while varying the chosen water amount. Random allocation helps reduce systematic differences. Replication across plants is more informative than one plant alone.
第 3 步：公开结果并修正Step 3: Share results and revise
结果符合预期，就永远证明了吗？Does a matching result prove the claim forever?
记录方法、数据和例外，方便别人检验。支持证据会提高信心，却不保证绝不修正。天文学等领域也用观察研究，科学不只有一种固定步骤。Record methods, data and exceptions so others can examine them. Supporting evidence raises confidence without guaranteeing permanent certainty. Observational fields such as astronomy show science is not one rigid sequence.
🎮 你来探索与判断🎮 Explore and reason
先操作实践台，再用四个挑战检验理解。每次判断都能看见理由。Explore the practice table, then try four challenges. Each judgment comes with a reason.
一句话记住它：科学方法让解释接受公开证据的检验与修正。Remember: Scientific methods expose explanations to public evidence, testing and revision.
问题要明确到可以检验。Make questions testable.比较时留意混杂因素。Watch for confounders in comparisons.支持不等于永远不可修正。Support does not make a claim unrevisable.

具体学科使用不同方法。随机试验不是所有问题的唯一方法；此例只是可控植物实验。Disciplines use different methods. Randomized experiments are not the sole approach to every question; this example is a controllable plant study.
