200 Biology Research Topics For High School

Research papers are an integral part of high school. A detailed research paper is required in most of the subjects, and one just cannot back out, as this is a part of their curriculum. However, what is even more laborious than writing the whole research paper? Finding a good topic!

The same goes for biology. Although there are plenty of topics out there that a student can write about, choosing a relevant topic is often a taxing job since they may need to brainstorm various factors. However, it can be disentangled with clarity and appropriate counsel. 

While this subject deals with various areas like cells, animals, plants, and human anatomy; in this post, we would appraise you with 200 biology research topics handpicked for aspiring high schoolers, to make their task easier.

Biology Research Topics- Finding the Right one 

Choosing the right topic can be a long expedition. However, it can be effortless when students are clear about their requirements personally and academically. To discern the same, it can be a fair idea to look into some crucial attributes that can lead a high schooler towards a desired biology research topic.

  • Know your niche

Learners often have one or more notions that they feel enticing to learn and travel with. For instance, a student may like to learn and work in cell biology, while another may love studying more about genetics. Knowing the niche in which they can excel can make their topic selection facile.

  • Stick to one Narrow topic

After comprehending the choice of the niche, the scholar may need to narrow down to one topic which is intriguing and manageable at the same time. Evidently, “Study of Mitochondria and its benefits ” is a better choice than “Cell biology”. Choosing a righteous narrow topic may mitigate the constraints like taxing research and report length later. 

  • Consult mentors and Peers

Instructors are always available to answer the queries of pupils. Students can take their inputs to add strength to their research topics. Mentors not only assist to choose the right topic but also can advise a few changes in the choice to make it finer. Say, a student has chosen “Study of DNA”, the mentor can suggest modifying it to ”Role of DNA in Curing Diseases”. Brainstorming sessions with peers may also ameliorate the topic decision 

  • Ensure the School Regulations 

High school research is often guided by some crucial regulations to stipulate students work efficiently. Students may need to choose a topic somehow related to the academic syllabus. Further, they may be stimulated to address burning issues to create awareness. Adhering to the guidelines can mitigate the need for rectifications later.
