Answer:

1। A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research,in a process beginning with an educated guess or thought.

A project of problem of plastic and its recycling.

2: objectives : to study about the use of plastic and the problems caused by them.

3: review of literature : The book of community medicine by K Park  was used as a source of review of the literature

4: relevance : a large number of waste started accumulating on the outskirts of the city due to the increase in the dumping of the plastic equipments and plastic bags. They are non biodegradable and hence are not breaking down into smaller pieces.

6: description of the method followed : Descriptive type of study was followed

7: observation : it was observed that plastic is more often used because various type of people use it for various type of purposes. Since is light and durable it is more often used as compared to other degradable products like jute.

8: analysis : the use of plastic should be stopped as early as possible.

9: results/conclusion/finding: plastic not only degrades the quality of the soil but also clocks the train and stop the flow of sewage water. it takes a lot of time to degrade plastic. Plastic if at all needed to be used then it should be used as a recyclable product. People should be made aware about when to use plastic and how to degrade it. we should all help each other for the purpose of recycling of the plastic for protection of the environment.

10: your opinion/suggestions/follow up etc : a similar type of descriptive study will be conducted after one year to find the change in the education level and the the use of plastic for the household activities.
