摘要:
该高中英语课件围绕“科学思维与科学家的探究方法”主题,通过Opening Page的主题引入(科学思维的本质)、实验室图片分析(识别安全护目镜、烧杯等科学设备词汇)、实验意义讨论(验证假设、协作的重要性)、爱因斯坦名言解读(创造性思维的价值)到个人经历分享(实验室体验与职业意向),搭建从感知科学情境到理解科学研究本质的学习支架。
其亮点在于融合语言能力(科学词汇学习、问题设计如“如何击败霍乱威胁”的问答训练)、思维品质(科学研究步骤排序活动,从发现问题到得出结论的逻辑梳理;图表匹配中证据与结论的对应分析,培养证据意识),采用任务链教学法。学生在活动中提升语言表达与科学思维,教师可直接使用结构化活动方案,提高教学效率。

选必二 Unit 1 Science and scientists
Opening Page & Reading and Thinking
重庆市黔江中学校 彼得大帝
Step1. Opening Page
1.What is the theme of this unit ?
The theme of this unit is great scientific minds and the powerful ways in which they interpret the world, analyze problems, and affect real change in our world.
2.How would you describe the photo?
Two young girl students are conducting an experiment in a school science laboratory ,probably to test a theory ,verify(验证) results ,collect data , or develop skills needed in scientific research.
3.What scientific equipment can you see in a science laboratory?
Safety goggles(防护眼镜) ,glass rod(玻璃棒) , beaker(烧杯), gauze mat(石棉网), tripod(?) , Bunsen burner(本生灯) , stand(托架) , flask(烧瓶) ,test tube(试管) ,test tube rack试管架 , etc.
4.Why do we need to conduct experiments?
Experiments are an essential part of the scientific process. They allow scientists to test their hypotheses(假说、假设), gather data, and draw conclusions about the natural world. Without experiments, our understanding of the world would be limited, and we would not be able to make progress in fields such as medicine, technology, and environmental science.
Students engaged in this kind of laboratory learning can gain first-hand knowledge of scientific elements , rules of natural phenomena , and the exponential power(指数级的力量) of collaboration(协作、合作).
5.How do we understand the quote?
To raise new questions, new possibilities , to regard old problems from a new angle , requires creative imagination and marks real advance in science.
---Albert Einstein & Leopold Infeld
提出新的问题,发现新的可能,从新的角度审视已存在的问题,这些需要创造性的想象力,并标志着科学的真正进步。
It means that the real mark of a scientist is the ability to ask questions and to see things in a new way ,and this requires creativity.
6.Have you ever been to a place like this ?What was it like?
Yes , I have .I have conducted chemistry experiments in the laboratory at my school . There are lots of beakers , Petri dishes(培养皿) , and other tools and equipment there. We are set in teams and work together to complete experiments at various workstations.
7.Would you like to work in such a field in the future ? Why or why not?
I would like to work in science because such work can help me better understand the world ,appreciate the world at different levels ,and make a difference in people’s lives . I would also be able to develop new technologies , find cures , solve practical problems , make informed decisions , and work on things that interest me.
I wouldn’t like to work in science because I’m outgoing and I can’t stand staying in the laboratory day and night.
Step2.Reading
Activity 1. Discuss the following stage of scientific research in groups . What order would you put them in ?
_____analyze the results ______ask a question
______ draw a conclusion ______collect data
______find a problem ______find supporting evidence ______think of a method
Activity 2.Skim the passage to see if the order you decide in Activity 1 was correct.
_____analyze the results ______ask a question
_____ draw a conclusion ______collect data
_____find a problem ______find supporting evidence _____think of a method
