Solution to the problem
After the steps like observation, survey, experiments, data analysis and drawing conclusions, you have to take steps to solve the problem in the real sense. You must find a more or less permanent solution to the problem under study. For example, if you are working on a project on household solid waste, you may conclude that the waste should be composted (ordinary compost or vermicompost). The solution should be tried first in your own house and then in the houses of 10/15 of your neighbours. Has the problem eased to some extent? Find an answer to this question and record your findings in the report.
N.B. The steps of a project discussed above are given simply as a guideline. There is no compulsion that you follow all the steps we suggested. If you think that you have a better way of doing the project, then go ahead. Your project will fit in NCSC as long as you do not deviate from the basic guidelines.
