How to write a campus science practice survey report ah 20

1. Question RaisedThis afternoon, I went for a walk in Jishan Park. A trail is located on the side of the river around the city, like a long snake. As I walked down the trail, I suddenly noticed that our riverside around the city had changed dramatically.

The water is getting dirty! Why? I couldn't figure it out.

II. Investigation Methodology.

1. Compare the Huancheng River a few years ago with the current Huancheng River.

3. Investigation.

Years ago: The Huancheng River is relatively clear, and herring fish can be seen everywhere. 6 years later: The water in the Huancheng River became dirty, leaving only a few fish wandering in the water, looking listless.

2. Duckweed grows on the banks of the river around the city, but there are not many of them. There was also a dead crucian carp floating on the river facing the square.

4 out of tourists said it was bad, with only 20% of the positive reviews and 80% of the bad reviews.

4. There is a sewage outlet that is discharging black * sewage, and there are many plastic bottles floating at the water outlet.

IV. Conclusions. 1. The reason why the water in the Huancheng River has become dirty is mainly related to the illegal discharge of sewage, and many factories have opened sewage pipes without the permission of the management department. The effluent contains industrial toxins, COD manganese and * (mercury), which cause excessive heavy metals in the river and cause slow* poisoning of fish.

If contaminated fish are eaten by anglers, the consequences can be devastating. I am gratified that the city has done a lot of work in this regard.

2. The quality of tourists is that the plastic bottles and garbage bags in the river cannot grow by themselves, and they must be the work of tourists. This involves the quality of tourists. The question of people's quality can only be educated and controlled by themselves.

In this regard, the city has also hung up signs, but the effect is minimal. I really don't have any good advice, and I regret it. But the river around the city is everyone's.

Since everyone created it, it needs everyone.

1. Topic. The requirements are clear, clear, concise and eye-catching.

3. Introduction (or preface, formulation of questions). The introduction is not the main part of the study, so it should be concise and to the point.

The content includes: 1. Putting forward research questions;

2. Introduce the background of the research;

3. Indicate the purpose of the research;

4. Clarify the hypothesis of the research;

5. Explain the significance of the research.

4. Research Methodology. Different research methods are available on different topics. This is an important part of the research report, and the experimental research method should be used as an example, and its content should include:

1. The object of the study and its sampling;

2. Application of instruments and equipment;

3. Control of related factors and irrelevant factors;

4. Procedures and methods;

5. Define the concept of *;

6. Statistical methods of research results.
