Follow-up Work
Task
Design the procedures and exercises before and after the field study to help students to construct
their knowledge.
Reminder:
As the assessment for learning is stressed, the construction of knowledge and attitude students
adopted in the field study are important.
Topic:
S4 field study on the fluvial processes and landforms and man’s impact on the environment of Tung
Chung River.
Objectives:
Knowledge / Concepts
1) Identify different fluvial processes operating in different courses of the Tung Chung River;
2) Describe and compare the characteristics of a river at different courses;
3) Compare and contrast the water quality of different sites along the river channel;
4) Point out the ways man modified the river channel;
5) Suggest some ways to maintain sustainable development of the Tung Chung River.
Skills
1) Apply map reading and interpretation skills in the field work;
2) Measure and test the stream velocity and pollution level at different check points;
3) Use of problem-solving skills to derive a plan for sustainable development of Tung Chung
River.
Values
1) Appreciate the beauty of nature;
2) Understand the importance of environmental conservation and maintaining the sustainable
development of a region.
Area of Study:
Check point 1 – SW end of Shek Mun Kap
Check point 2 – Bridge east of Shek Lau Po
Check point 3 – Confluence east of Ngau Au
Check point 4 – Estuary at Sha Tsui Tau
(017652) (landforms of upper course)
(022661)
(019664)
(019668) (landforms of lower course)
Questions for Investigation:
1)a) Identify the fluvial landform features at various check points.
b) Compare and contrast the fluvial processes and characteristics of different courses of the
Tung Chung River.
2)
Contrast the stream velocity and the water quality of stream in different check points.
Explain such differences.
3)a) What have been done to modify the river channel and stream flow? Why?
b) Why do environmentalists object to such modification work?
c) What could be done to maintain the sustainable development of this region?
