Finding good research topics is always the first step toward a successful essay. Without a feasible, appropriate, and fascinating subject, you risk working at something initially only to discover that your topic is boring or lacks possible information to support its arguments.

In this article, I would like to list 150 interesting research topics you can use for your school work. I sorted the list based on their year level and subject to make browsing easier.

If you want a more thorough explanation for some of my Top 10 Research Topics for the year 2021, check out the post below.

I. Research Topic Ideas per Year Level

A. Research Topics for Middle School Students

Middle school in the United States starts from Grades 6 and ends in Grade 8. This is usually the beginning when students are encouraged to think critically and apply their solutions to real-world problems. Thus, interesting research topics for middle school should focus on close scrutiny of the world they live in and applying theoretical knowledge to real-life scenarios.

Based on these criteria, here are some research topics for middle school students for the year 2021.

B. Research Topics for High School Students

As compared to middle school, high school students are those from grades 9 onwards. Having developed the foundation for their critical-thinking skills in middle school, high school students are now interested in developing their autonomy, developing community consciousness, and finding avenues for self-expression, among others. This is also the best time for students to think about their future education, career, and life, to name a few. As such, here are some of the best research topics for high school students.

  1. What are the benefits of daily exercise?
  2. Does the internet help news dissemination or proliferate fake news information?

C. Research Topics for College Students

College represents the phase in one’s academic life where the student starts to specialize in one field of study. However, compared to Masters’ and Ph.D. degrees, a significant portion of your college life would still be dedicated to general education subjects, which may include English composition, foreign language, natural sciences, and arts and humanities, to name a few.

Nevertheless, college students are expected to be better and more apt in researching, considering that they should have developed this in high school. Thus, research topics for college students should also reflect a level of ‘advancement’ and ‘critical thinking’ compared to research topics for high school students.
