The Unbalanced Glider Design Challenge 失衡滑翔机挑战项目

At this stage of the project students should attempt to redesign the unbalanced mini glider based on the evidence that they gathered during their initial experiment. While redesigning their plane students should be able to articulate their design choices and justify their decisions using evidence. Try to have students use the CER (Claim, Evidence, Reasoning) method when responding to your questions. You may also want to provide students with sentence stems to help them structure a proper scientific argument. For instance a sentence stem such as: “we observed that _____, therefore we decided to ____, because ______” could really help ESL students structure their thoughts and provide clear and concise arguments to express their hypothesis.

此项目中学生们应该根据他们在初始实验中收集到的证据，尝试重新设计不平衡的迷你滑翔机。在重新设计飞机时，学生应该能够清楚地表达他们的设计选择，并使用证据证明他们的决定是正确的。要求学生在回答问题时使用CER（声明、证据、推理）方法。可以给学生提供基本句型，例如，如：“我们观察到_____，因此我们决定_____，是因为_____” 此方法可以帮助ESL学生构建他们的思想，提供清晰简洁的论点来表达他们的假设。
