A. Are teens that play sports less likely to have jobs at the same time?
B. Would cutting extracurricular activities anger students?
C. Is there a correlation between extracurricular activities and grades?
D. How many teens participate in extracurricular activities every year?
Question C requires thorough research. It is not just a topic for one lecture, as the student needs time to find relative data to provide arguments. Thus, 4 to 5 pages will be enough to include several points of view, present some statistical data, and conclude everything.
Question c) “Is there a correlation between extracurricular activities and grades?” can be a topic for a research paper, as it discusses quite a broad topic. There can be different judgments and various surveys, so one or two pages won’t be enough to include all the data. This research can even become a background for a degree thesis.
