This unit engages students in situated learning and aims at improving students’ conceptual understanding, problem-solving skills and attitudes toward science.

This unit was designed for junior and senior high school students. It helps students develop scientific concepts and inquiry abilities through exploring ideas and concepts about water quality.? The unit is consisted of two major parts: (1) developing basic conceptions and inquiry abilities (Week 1 to Week 4); (2) conducting investigations about water quality (Week 5 to Week 9). The two parts gradually engage students in scientific inquiry and help them strengthen their understanding and competence. Following is the list of weekly topics and content:

1.Week one: Introducing the unit
2.Week two: Water temperature and pH value
3.Week three: Calibration of instruments and campus tour
4.Week four: Dissolved oxygen
