任務Task
Design and make a water treatment works model to simulate the water treatment process.
以下是食水處理過程的重温﹕First, let’s revise the water treatment process that you have learned:
你設計的濾水廠模型﹕Think about the design of your water treatment works model, it
- 應合乎比例。
- 應用簡單和易獲得的材料製成。
- 可以除去較大的雜物和細小的不可溶雜質。
- 可以提供穩定的水流。
- should be in scale.
- should be made using simple and available materials.
- can remove impurities including large and small insoluble impurities.
- can provide a steady water flow.
第一部分—設計濾水廠模型Part A—Design a water treatment works model
1.
在互聯網搜尋製作濾水廠模型的不同方法。列出你的設計所需的物料。
Search the Internet for different methods of making a water treatment works model. List the materials your group will choose to make the model.
2.
在以下的空位內繪畫你的設計，並在各部分加上標註。試簡單描述製作濾水廠模型的步驟。
Draw your design below. Label all the parts. Also, briefly describe how you will make the model.
3.
寫出你的設計的參考來源。
Write the source(s) of reference that your model is based on.
第二部分—製作模型和傳達結果Part B—Make the model and communicate results
1.
和組員在堂上合作完成濾水廠模型。
Collaborate with your group members to make the model in the lesson.
2.
在班上展示和介紹你組的濾水廠模型。
Present and display your model to the class.
第三部分—評價和改良Part C—Evaluate and redesign
1.
讓老師根據以下標準評價你組製作的濾水廠模型﹕
Ask your teacher to evaluate your water treatment works model using the following Grading Rubric:
(I) 水的流量(I) Flow rate
150毫升的濾液流出模型需要多少時間？
How long did it take to collect 150 mL filtrate from the model?
(II) 水的淨化(II) Water purity
(III) 總分(III) Total score
你製作的模型的總分數是 __________________。
The total score of your model is __________________.
2.
你認為哪一組的設計是最好的？寫出他們的設計的兩個優點。
Which group’s design do you think is the best? Write TWO advantages of their design.
3.
你可以如何改良自己的濾水廠模型呢？
What modifications can you make to your model?
4.
在課堂後提交學生工作紙。
Submit Student’s Worksheets to your teacher after the lesson.
