科学方法的步骤通常是进行观察,提出假设,设计实验来检验假设,进行实验,并确定假设是否被接受或拒绝。虽然学生经常可以陈述科学方法的步骤,但他们可能难以实际执行这些步骤。这个练习为学生提供了用科学方法亲身体验的机会。我们选择金鱼作为实验对象,因为学生们觉得它们有趣而有趣。当然,你可以使用任何主题或主题。这个练习需要的时间取决于你。我们建议使用3小时的实验室时间,但是项目可以在一个小时内完成,也可以在几天内完成,这取决于您计划参与的程度。金鱼缸Optimally,每个实验室都要一碗鱼。你可以和整个班级一起工作,如果班级很小,或者你可以随意要求学生分成几个小组。给学生们展示一碗金鱼。对金鱼做一些观察。让学生说出金鱼的特征,并进行观察。他们可能注意到鱼的颜色、大小、在容器中游泳的位置、它们与其他鱼的相互作用等。要求学生列出哪些观察涉及可以测量或限定的东西。解释科学家如何能够获取数据来进行实验,并且某些类型的数据比其他类型的数据更容易记录和分析。帮助学生识别作为实验的一部分可以记录的数据类型,而不是较难测量的定性数据或他们根本没有工具测量的数据。让学生根据他们的观察提出他们想知道的问题。列出他们在调查每个主题时可能记录的数据类型。让学生为每个问题拟定一个假设。学习如何提出一个假设需要练习,所以学生很可能会从头脑风暴中学习。把所有的建议都写在黑板上,帮助学生区分他们可以测试的假设和不能测试的假设。询问学生是否可以改进提交的任何假设。选择一个假设,并与全班同学一起设计一个简单的实验来测试这个假设。收集数据或创建虚构的数据,并解释如何检验假设,并根据结果得出结论。让实验组选择一个假设并设计一个实验来测试它。如果时间允许,让学生进行实验,记录和分析数据,并准备实验室报告。

The steps of scientific methods are usually to observe, make hypotheses, design experiments to test hypotheses, conduct experiments, and determine whether hypotheses are accepted or rejected. Although students can often state the steps of scientific methods, they may find it difficult to implement them in practice. This exercise provides students with the opportunity to experience it scientifically. We chose goldfish as subjects because the students found them interesting and interesting. Of course, you can use any theme or theme. The time required for this exercise depends on you. We recommend three hours of lab time, but the project can be completed in an hour or in a few days, depending on how much you plan to participate. Goldfish tank Optimally, each laboratory needs a bowl of fish. You can work with the whole class, if the class is small, or you can ask the students to divide into groups at will. Show the students a bowl of goldfish. Do some observation on goldfish. Let the students tell the characteristics of goldfish and observe them. They may notice fish’s color, size, swimming position in the container, their interaction with other fish, etc. Students are asked to list what observations involve things that can be measured or limited. Explain how scientists can get data for experiments, and some types of data are easier to record and analyze than others. Help students identify data types that can be recorded as part of the experiment, rather than qualitative data that are difficult to measure or data that they do not have tools to measure at all. Ask students to ask questions they want to know based on their observations. List the data types they may record when investigating each topic. Ask the students to make a hypothesis for each question. Learning how to make a hypothesis requires practice, so students are likely to learn from brainstorming. Write all the suggestions on the blackboard to help students distinguish between hypotheses they can test and hypotheses they can’t test. Ask students if they can improve any assumptions submitted. Choose a hypothesis and design a simple experiment with the whole class to test it. Collect data or create fictional data, explain how to test hypotheses, and draw conclusions based on the results. Let the experimental group choose a hypothesis and design an experiment to test it. If time permits, let students carry out experiments, record and analyze data, and prepare laboratory reports.
