212 Unique Biology Research Topics For Students And Researchers

biology research topics

Every student studying something related to biology — botany, marine, animal, medicine, molecular or physical biology, is in an interesting field. It’s a subject that explores how animate and inanimate objects relate to themselves. The field unveils the past, the present, and what lies in the future of the relationship between the living and nonliving things.

This is precisely why you need custom and quality biology topics for your college and university essay or project. It’ll make it easy to brainstorm, research, and get to writing straight away. Before the deep dive, what is biology?

What Is Biology?

Everyone knows it’s the scientific study of life, but beyond that, biology facilitates the comprehension of living and nonliving things. It’s a branch that explores their anatomy, behavior, distribution, morphology, and physiology.

For example, it understands how genes are classified and constituted into generations. It encompasses various branches, including botany, medicine, genetics, ecology, marine biology, zoology, and molecular biology.

Here are what some of these mean:

Botany: This study of plants examines their structure, physiology, ecology, economic importance, and distribution, among others. It also deals with their biochemical processes, properties, and social interactions between plants. It extends to how plants are vital for human life, survival, and growth and how they play a significant role in stabilizing environmental health. Zoology: Zoology studies animal behavior, brain, structure, physiology, class, and distribution. It’s the general study of the lives of both living and extinct animals. It explains animal classification, the animal kingdom, evolution, habitat, embryology, and life span. Physiology: Physiology deals with the daily functions of the human body: How it works and the factors that make it work. It examines molecular behavior, the chemistry and physics behind locomotion, and how the cells in the living organisms’ body function. It helps understand how humans and animals get sick and what can be done to alleviate pain. Microbiology: Dealing with microorganisms, it examined how viruses, algae, fungi, bacteria, protozoa, and slime molds become parts of human life. They’re regarded as microbes, which play substantial roles in the human biochemical processes, including climate change, biodegradation, biodeterioration, food spoilage, biotech, and epidemiology. Marine Biology: This is the scientific study of organs in the sea. It understands their family classification, how they survive, and what makes wild marine animals different from domesticated and consumable ones. It also explores their interaction with the environment through several processes. The marine biologist studies marines in their natural environment, collects data on their characteristics, human impact on their living, and how they relate with themselves.

Now that you know all these, here are some custom biology topics to research for your university or college essay and paper.

What is a good hypothesis in biology?

A good hypothesis in biology is a statement that offers a tentative explanation for a biological phenomenon, based on prior knowledge or observation. It should be:

  • Testable: The hypothesis should be measurable and can be proven false through experiments or observations.
  • Clear: It should be stated clearly and without ambiguity.
  • Based on Knowledge: A solid hypothesis often stems from existing knowledge or literature in the field.
  • Specific: It should clearly define the variables being tested and the expected outcomes.
  • Falsifiable: It’s essential that a hypothesis can be disproven. This means there should be a possible result that could indicate the hypothesis is incorrect.

What is an example of a hypothesis statement in biology?

Example: “If a plant is given a higher concentration of carbon dioxide, then it will undergo photosynthesis at an increased rate compared to a plant given a standard concentration of carbon dioxide.”

In this example:

  • The independent variable (what’s being changed) is the concentration of carbon dioxide.
  • The dependent variable (what’s being measured) is the rate of photosynthesis. The statement proposes a cause-and-effect relationship that can be tested through experimentation.

How to Write a Biology Hypothesis – Step by Step Guide

A hypothesis in biology is a critical component of scientific research that proposes an explanation for a specific biological phenomenon. Writing a well-formulated hypothesis sets the foundation for conducting experiments, making observations, and drawing meaningful conclusions. Follow this step-by-step guide to create a strong biology hypothesis:

1. Identify the Phenomenon: Clearly define the biological phenomenon you intend to study. This could be a question, a pattern, an observation, or a problem in the field of biology.

2. Conduct Background Research: Before formulating a hypothesis, gather relevant information from scientific literature. Understand the existing knowledge about the topic to ensure your hypothesis builds upon previous research.

3. State the Independent and Dependent Variables: Identify the variables involved in the phenomenon. The independent variable is what you manipulate or change, while the dependent variable is what you measure as a result of the changes.

4. Formulate a Testable Question: Based on your background research, create a specific and testable question that addresses the relationship between the variables. This question will guide the formulation of your hypothesis.

5. Craft the Hypothesis: A hypothesis should be a clear and concise statement that predicts the outcome of your experiment or observation. It should propose a cause-and-effect relationship between the independent and dependent variables.

6. Use the “If-Then” Structure: Formulate your hypothesis using the “if-then” structure. The “if” part states the independent variable and the condition you’re manipulating, while the “then” part predicts the outcome for the dependent variable.

7. Make it Falsifiable: A good hypothesis should be testable and capable of being proven false. There should be a way to gather data that either supports or contradicts the hypothesis.

8. Be Specific and Precise: Avoid vague language and ensure that your hypothesis is specific and precise. Clearly define the variables and the expected relationship between them.

9. Revise and Refine: Once you’ve formulated your hypothesis, review it to ensure it accurately reflects your research question and variables. Revise as needed to make it more concise and focused.

10. Seek Feedback: Share your hypothesis with peers, mentors, or colleagues to get feedback. Constructive input can help you refine your hypothesis further.

Tips for Writing a Biology Hypothesis Statement

Writing a biology alternative hypothesis statement requires precision and clarity to ensure that your research is well-structured and testable. Here are some valuable tips to help you create effective and scientifically sound hypothesis statements:

1. Be Clear and Concise: Your hypothesis statement should convey your idea succinctly. Avoid unnecessary jargon or complex language that might confuse your audience.

2. Address Cause and Effect: A hypothesis suggests a cause-and-effect relationship between variables. Clearly state how changes in the independent variable are expected to affect the dependent variable.

3. Use Specific Language: Define your variables precisely. Use specific terms to describe the independent and dependent variables, as well as any conditions or measurements.

4. Follow the “If-Then” Structure: Use the classic “if-then” structure to frame your hypothesis. State the independent variable (if) and the expected outcome (then). This format clarifies the relationship you’re investigating.

5. Make it Testable: Your hypothesis must be capable of being tested through experimentation or observation. Ensure that there is a measurable and observable way to determine if it’s true or false.

6. Avoid Ambiguity: Eliminate vague terms that can be interpreted in multiple ways. Be precise in your language to avoid confusion.

7. Base it on Existing Knowledge: Ground your hypothesis in prior research or existing scientific theories. It should build upon established knowledge and contribute new insights.

8. Predict a Direction: Your hypothesis should predict a specific outcome. Whether you anticipate an increase, decrease, or a difference, your hypothesis should make a clear prediction.

9. Be Focused: Keep your hypothesis statement focused on one specific idea or relationship. Avoid trying to address too many variables or concepts in a single statement.

10. Consider Alternative Explanations: Acknowledge alternative explanations for your observations or outcomes. This demonstrates critical thinking and a thorough understanding of your field.

11. Avoid Value Judgments: Refrain from including value judgments or opinions in your hypothesis. Stick to objective and measurable factors.

12. Be Realistic: Ensure that your hypothesis is plausible and feasible. It should align with what is known about the topic and be achievable within the scope of your research.

13. Refine and Revise: Draft multiple versions of your hypothesis statement and refine them. Discuss and seek feedback from mentors, peers, or advisors to enhance its clarity and precision.

14. Align with Research Goals: Your hypothesis should align with the overall goals of your research project. Make sure it addresses the specific question or problem you’re investigating.

15. Be Open to Revision: As you conduct research and gather data, be open to revising your hypothesis if the evidence suggests a different outcome than initially predicted.

Remember, a well-crafted biology science hypothesis statement serves as the foundation of your research and guides your experimental design and data analysis. It’s essential to invest time and effort in formulating a clear, focused, and testable hypothesis that contributes to the advancement of scientific knowledge.

Don’t know what to write about in your essay on biology? Looking for good biology essay examples for inspiration? This article has all you need!

A biology essay is a type of academic paper that focuses on a particular topic of biology. It can discuss animal life, cycles in biology, or a botanic subject. You will need to demonstrate your critical thinking skills and provide relevant evidence to support your perspective.

On this page, you will find examples of biology essays. You will also find here tips and topics prepared by our experts . They can assist you in nailing your short or extended essay.

Areas of Research for Biology Essays

If you’ve been assigned to write a biology essay, you probably know which area of research you have to choose. However, it might be beneficial to explore other available scopes. It’s useful for both interdisciplinary study and the cases when you are free to pick your area of research. In this section, let’s figure out what you can study in biology.

Here are biological areas of research you should be familiar with:

  • Cancer Biology studies this type of disease to prevent, detect, diagnose and cure it. The ultimate goal of such biologists is to eliminate cancer.
  • Cell Biology is a branch that studies the structure, function, and behavior of cells. Here, biologists study healthy and sick cells to produce vaccines, medication, etc.
  • Biochemistry is an application of chemistry to the study of biological processes on cell and molecular levels. It is a cross-discipline between chemistry and biology. The focus is on the chemical processes of living organisms.
  • Computation Biology is a study of biological data that develops algorithms and models to understand biological systems. Here, scientists either work for institutions or research for private enterprises.
  • Genetics is an area that focuses on the study of genes and genetic variations for health benefits. It looks at the way DNA affects certain diseases.
  • Human Disease is an area within which scientists study different diseases. The field covers cancer, developmental disorders, disease genes, etc.
  • Immunology is a branch of biology that focuses on immunity. Immunologists look at the way the body responds to viruses as a way to protect the organism.
  • Microbiology studies all living organisms that are too small for our eye to see. It includes bacteria, viruses, fungi, and other microorganisms.
  • Neurobiology is the study of the nervous system. Biologists examine the way the brain works and look into brain illnesses.
  • Stem Cell and Developmental Biology seeks to examine how the processes behind stem cell’s ability transform cells. The biologists in this area use the power of stem cells to model human illnesses.

Essay on Biology: Writing Tips

Want to know how to start a biology essay? Wondering about the best way to write your essay on biology? Then check out the following tips.

When you’re writing about biology, pay attention to the following features:

  • Introduction . Just as in any other form of academic writing, the first section of your paper introduces the subject. Here, explain why your ideas are relevant to biology as a science.
  • Thesis Statement. The final one or two sentences of the first paragraph should include your original hypothesis and experiment. You will be proving them in the main body. You do not have to include the results as the reader will encounter them later. If you’re struggling with this part, try our thesis generator .
  • Main Body. In this part, write about all the experiments in detail. Often, teachers require to include visual aid to prove your point. For Zoology, Anatomy, Botany, it is pretty easy to find some photos and illustrations.
  • Conclusion. Here, restate your thesis. Reemphasize the most critical aspects described in the main body. You can do it by using our summarizing tool . The goal of this last paragraph is to leave an everlasting impression on the reader.

Thank you for reading our article. We hope you found it helpful. Share it with your class peers who also study biology. Additionally, have a look at the biological essay examples below.

  • Thesis Guidelines

A thesis for Distinction in Biology is a wonderful way for you to close the loop on your undergraduate research experience and showcase your scientific scholarship. Your thesis will be evaluated by the Faculty in Biology and answers the following questions: What did you do? Why did you do it? What is the significance of your results? What else would you do, were you to continue the project?

In answering the above questions, you have an opportunity to demonstrate your understanding and intellectual ownership of a project; not simply your productivity in the lab. The volume of results or completeness of the study is not critical for a successful thesis. Instead, we will be looking for the following:

  • An argument for the significance of your research, contextualized within the scientific literature;
  • A review of appropriate literature as evidence in support of claims you make in your argument;
  • A statement of your research goals, i.e., a meaningful question of biological importance;
  • A description of experimental approaches and methods ;
  • Appropriate presentation of results through tables, figures, and images;
  • A discussion of the meaning and significance of your results;
  • A description of limitations and future directions for the project.

Expanded guidelines can be found in the Biology Thesis Assessment Protocol (BioTAP):

Format of the Thesis

The basic format of the thesis should resemble that of any scientific journal article that is common in your subdiscipline. It generally includes the following sections: Introduction & Background; Methods; Results; Discussion; Acknowledgements; and References. In some instances, it may be useful to sub-divide the Methods & Results section to correspond to multiple aims. However, if you chose to take this route, remember that there should still be a general Introduction and Discussion sections that address the project as a whole. The thesis should not consist of several "mini-papers" that are unconnected.  

Submission Guidelines

The format of the final copy should follow these guidelines:

  • Cover Page ( sample ): Title; student's name; supervisor's name; date of submission; 3 signature lines at bottom right (Research Supervisor, DUS, Reader). Please follow the format and language of the sample.
  • Abstract Page: single-spaced, roughly 250 words.
  • Thesis should be double-spaced
  • Pages should be numbered at the top right corner of the page
  • It is preferred that figures are embedded within the document instead of all at the end
  • There is no minimum page requirement or limit, although most are approximately 25 pages. 

Sample Theses

Examples of Distinction papers from previous years are available for examination in the Undergraduate Studies Office (Rm 135 BioSci).  Several samples are also available below as PDF files.

  • Tracing the origins of antimalarial resistance in Plasmodium vivax
  • Interaction network optimization improves the antimicrobial efficacy of phage cocktails
  • Identifying how ufmylation of RAB1B regulates IFN-β signaling

Essays About Biology: Top 5 Best Examples and 6 Prompts

Writing essays about biology can be difficult because it’s composed of many subtopics. Check out this article for our top essay examples and writing prompts.

Biology came from the Greek words “bios” (life) and “logos” (study). It’s why biology is the study of life or living organisms. Aside from being a natural science, it also has consolidated themes, such as cells making all organisms. Because it’s a broad topic, biology is divided into specialized fields such as botany, genetics, zoology, microbiology, medicine, and ecology. 

Biologists consider living beings’ origin, evolution, growth, function, structure, and distribution. It’s a comprehensive subject, so there are many things you can write about in your essay. However, at the same time, you might find it challenging to focus on just one area. 

Below are examples to give you an idea of how to write your essays about biology:

1. Essay About Biology by Kelli Wilkins

2. my interests in biology by anonymous on essaywriting.expert, 3. essay on the importance of study of biology by akhila mol, 4. what biology means to me by anonymous on studymode.com, 5. how my biology teacher changed my perspective of learning the subject by sankalan bhattacharya, 1. biology in my everyday life, 2. something i realized because of biology, 3. my memorable biology class experience, 4. genetics’ role in people’s diseases, 5. my experience during the pandemic, 6. biology and health.

“Studying Biology is important for a number of reasons, but in particular because it is used in every field. If we did not have a good understanding of Biology then nobody would be able to understand how bodies work, and how life on earth functions.”

Wilkins shares her desire to study anatomy, a branch of biology, and expounds on what makes biology an essential field. Because biology lets people know more about the world, she digs into why she’s interested in anatomy, specifically to find ways to cure illnesses and develop technologies to discover new treatments. She ends her essay by relating biology to the existence of doctors and hospitals. 

“It is known that education plays an important role in the life of any individual. It gives an opportunity to develop personality and gain specific skills, to get profound knowledge and experience in order to apply them practically in the future. As for me, my major goal is to study Biology in order to get appropriate knowledge and skills required for my future profession.”

The author shares why they want to study biology, referring to the human body as the “perfect machine” and curious about how it performs each of its systems’ functions. The writer also mentions how biology is critical to their future profession. They aim to help people with their health problems and relay their desire to research the brain to find more data on it. 

“The study of biology owes great significance in human life, because man for its day-to-day requirements is dependent on plants and animals either directly or indirectly.”

Mol lists seven reasons why humans need biology in their daily lives. Her list includes health, diseases, agriculture, horticulture, food, animal breeding, and entertainment. She expounds on each point and how they affect a man during his time on Earth. She explains each relationship in a simple manner that’s easy to understand for the readers.

“Without biology, we would have no idea about an organism’s makeup, or the most basic unit of life, a cell… Biology influences me in many ways. Biology influences me by teaching me why to take care of the environment, why I am to take care of my body, and by giving me a better overall view of all scientific areas of study.”

In this short essay, the writer lists down reasons why biology is essential. These reasons include taking care of the environment, one’s body, and others. The author also expounds on their reasons by presenting facts supporting biology’s importance to the world and human lives.

“He told that the syllabus may be a good way to prepare for an exam but our knowledge should not be limited to any syllabus and the questions that were asked in the examination were related to the topic only. He told that if we try to know things in detail and understand them properly then the interest in the subject will develop, otherwise, students will not treat the subject as a subject of their choice. 

Bhattacharya shares his experience with a teacher with a unique teaching style. His Biology teacher from Class 7, before the era of the internet, don’t just carry one book to get all his lessons from. Instead, he has a notebook with the collated information from many books to teach his class. 

Bhattacharya’s teacher taught them things that were not in the curriculum, even if following the curriculum would give him higher points in his evaluation. He only wanted his students to learn more and share with them why learning differs from just knowing.

6 Prompts for Essays About Biology

Prompts for essays about biology

You don’t have to be a biology student to write an essay about the subject. If you’re looking for easy prompts to write about, here are some to get you started:

If mitochondria are the powerhouse of the cell, who is the powerhouse of your classroom? Your home? Relate a biology topic to a similar structure in your life, then explain why you think they are the same. 

For instance, you can compare your mother to mitochondria which generate the energy needed to power a cell. The cell being you. You can say that she gives you energy every day by being there and supporting you in whatever way she can. This prompt bodes for a creative and intriguing essay.

Relay a lesson you learned from biology and how it perfectly explained something you were once hesitant about. Such as being insecure about your big ears – only to know from a biology trivia that ears never stop growing. You can then share how this help lessen your insecurity because you now know large ears are normal. 

Do you have a memory you won’t forget that happened during biology class? Narrate this story and explain why it’s something that left an impression on you. To give you an idea, you can talk about the first time you dissected an animal, where you first realized how complex organisms are and that they are made of many systems to function, no matter how small.

Gene action and heredity are evolving. If you have a genetic illness or know someone who has it, you can share your experience. Then explain what your genes have to do with the disease. Is it something you got from your parents? Did they inherit it from your grandparents? Finally, you can add what your parents’ and grandparents’ lives were like because of the disease.

Virology, another branch of biology, studies viruses and viral diseases. A recent example is the coronavirus pandemic, where more people realized the importance of knowing a virus’ origin, structure, and how they work. Write an essay where you explain how the pandemic operates, such as why people should wear masks, social distance, etc.

For this essay, you can write about how biology helps you care for your health. For example, you can include how biology helped doctors give you the appropriate diagnosis, how you had the opportunity to have the proper treatment, etc. 

If you want to write on a related topic, here are essay topics about nature you can consider for your next essay.

Honkomp Thesis Defense

Raptor Biology student Nora Honkomp holding a hatch-year red-tailed hawk in Idaho foothills

Boise State University MS Raptor Biology student Nora Honkomp defended her thesis, “Biological and Environmental Factors Associated with the Autumn Migration Timing of North American Raptors” on the morning of March 7, 2024. Honkomp’s main advisor is Julie Heath (MS, Raptor Biology, ’96; Boise State University Raptor Research Center ; Biological Sciences ) , and her committee includes Trevor Caughlin (Biological Sciences) and Peter Olsoy of the USDA Agricultural Research Service.

Migration is an energetically expensive and risky event in the life cycles of many organisms. The timing of migration departure from the summer breeding grounds is important for determining the probability of survival and physical condition upon arrival at wintering sites. Many internal and external factors affect departure timing and its variability, and the conditions that are most important for determining timing are likely to be different across species, depending on their traits. I studied the life history correlates associated with the timing of departure for North American raptor species and explored the specific weather conditions shaping several species’ departure timing. I used data from eBird to calculate spatially explicit autumn departure timing for 15 migratory raptor species across the United States and Canada from 2011 to 2021. I found a negative effect of latitude (northern birds departing before southern birds) and this effect was stronger in short-distance migrants compared to long-distance migrants. Further, socially migrating species tended to depart earlier than species that migrate alone, and larger-bodied species tended to depart later than smaller species. Finally, long-distance migrants, diet specialists, and social migrants had more consistent departure timing compared to short-distance migrants, diet generalists, and solitary migrants who were more variable in timing. Next, I selected the four raptor species with the greatest eBird data availability (Broad-winged Hawk, Osprey, Swainson’s Hawk, and Turkey Vulture) and assessed their departure timing within a latitudinal band across the northern U.S. from 2002 to 2021. Using weather data from Daymet and a sliding time window analysis, I determined the most likely periods of sensitivity of four weather variables on each species’ departure timing: maximum and minimum temperature, precipitation, and snow-water-equivalent. I then combined these season-specific weather variables for each species and identified their effect on departure timing. Finally, I used data from NA-CORDEX to forecast the departure timing of all four species to 2075. The forecast analysis showed that, over the next 50 years, Swainson’s Hawks will advance their departure timing (depart earlier in the year) and Turkey Vultures will delay migration departure (depart later in the year). Combined, these analyses further our understanding of the relationships between life history traits and departure and provide new insight into factors associated with annual variation in migration timing, which may underlie vulnerability to changing environmental conditions. Additionally, it identifies unique environmental factors related to the timing of autumn departure for four common species and provides estimates of future changes in an important part of their full annual cycles.

Honors Thesis

General information about honors in biology.

Rebecca Dobbins '16 studies fin regeneration in zebra fish using the Leica scanning confocal microscope for her senior thesis research.

Rebecca Dobbins ’16 studied fin regeneration in zebra fish using the Leica scanning confocal microscope for her senior thesis research.

In contrast to Latin honors ( cum laude , magna cum laude , summa cum laude ), which are based solely on overall GPA, achieving honors in one’s major is determined by a rigorous thesis process. This achievement appears on a graduate’s transcript as, for example, Honors in Biology. In Biology, any student may apply to conduct an Honors Thesis.

The Honors Thesis differs from a regular senior thesis in several key regards, all detailed below. (1) The research and writing are expected to meet a higher standard for rigor and scope. (2) The Honors candidate defends the thesis orally in front of a panel of examiners. (3) The deadline for thesis submission is earlier than for non-honors theses; this may seem trivial now but can become more important as the deadline approaches!  Although the details of achieving Honors in the major are somewhat specific to each department and program, there are some commonalities to the Honors Program as described here: https://www.bates.edu/honors/ .

Because of the high expectations for Honors Theses, and because of the relatively early deadline for submission of Honors Theses, an early start is crucial. The actual research project can begin during the junior year as an independent study, during the summer between the junior and senior years, or during the senior year itself. Honors Thesis work must extend over at least two semesters, by registering for Bio 457 & 458. Proposals for collaborative work may be considered by the department.

An Honors Thesis must be presented and defended orally at the end of the final semester. This oral examination covers the thesis and topics related to the thesis, including biology in general. For the oral defense, an Honors Panel is assigned specifically for each student and comprises one faculty member from the Biology Department, one Bates faculty member outside Biology, and one outside examiner from off campus (who has expertise in the relevant field but has not had input into the project). The student’s research advisor will also be present to ask questions but cannot vote on the outcome. The Honors Panel determines whether Honors is awarded, based on a combination of the written work (60%) and the oral defense (40%).

TIMETABLE FOR HONORS IN BIOLOGY

Winter Semester of the Junior Year

Meet with potential advisors to discuss summer plans and the possibility of doing Honors; it doesn’t hurt to start these conversations in the fall of the junior year.

Summer between Junior and Senior Years

Spend the summer either conducting research with your advisor or reading and planning in preparation for a full-speed start in the fall semester.

Fall of Senior Year

Submit a written proposal to your biology thesis advisor by the 10th day of classes in the first

Research posters and publications produced by Larissa Williams and her Bates students.

Research posters and publications produced by Larissa Williams and her Bates students.

semester of the senior year. Students whose proposals are approved by the department then can begin (or continue) an in-depth research project under the guidance of the individual faculty advisor.

Winter of Senior Year

At the first Biology faculty meeting of the winter semester, the department will discuss each Honors candidate’s progress and decide whether the student should proceed with the official Honors nomination process.

Details for the remaining steps of the process, including exact deadlines for the current academic year, are available at https://www.bates.edu/honors/ .

  • Work with faculty mentor to submit an Honors Nomination Form to the Honors Program by the Program’s January deadline of the student’s final semester.
  • Submit a thesis abstract to the Honors Program by the late-January deadline.
  • Upload the completed thesis to SCARAB by the late-March deadline.
  • Conduct an oral defense of the thesis by the late-April deadline.
  • Upload a revised thesis, if necessary, by the early-May deadline.

Honors candidates are also encouraged to present their work at the Mount David Summit in late April and/or at a regional or national conference.

Withdrawing from Honors Consideration

If, at any time prior to the submission of the written thesis, the thesis advisor feels that the student is not meeting the department’s expectations for a satisfactory Honors Thesis, the advisor has the authority to withdraw the student from the Honors Program.  Likewise, withdrawal may be initiated by the student, at any time prior to the thesis submission deadline or oral exam date.  Withdrawal forms are available on the Honors Program website.

STANDARDS AND EXPECTATIONS FOR HONORS IN BIOLOGY

Receipt of Honors in Biology is a special distinction awarded to those students who have excelled in their academic accomplishments at Bates and have completed a rigorous and substantive thesis project.  The distinction of Honors requires that the student and the thesis meet all of the criteria specified below.  An outstanding performance in several of the expectations for Honors may offset a less than exemplary performance in another area, but a significant deficiency in any one expectation is sufficient grounds to deny Honors. The Honors Panel, who may consult with the advisor, has final authority for judging whether the student has satisfactorily met the criteria for receipt of Honors.

The thesis must explore a novel question or topic, with creative and independent intellectual work by the student.

The thesis should describe a project that, if brought to completion, would be suitable for publication in the peer-reviewed literature, either as a stand-alone item or as part of a larger project.  The department recognizes that two semesters of work is seldom sufficient to complete a project to the point of a peer-reviewed publication, but the project should be on a trajectory for such an outcome.

In the written thesis and oral defense, the student must demonstrate a thorough understanding of the theoretical and methodological underpinnings of the project.  The thesis must develop the necessary background, theory and/or methodology via a thorough discussion and citation of relevant primary literature.

The student must demonstrate a high level of self-motivation, independence, and continuous engagement over the duration of the project.

The student must demonstrate that considerable progress has been made in the actual execution of the project. The student must have advanced the project to the stage where defensible conclusions can be drawn.

The thesis must be well written and accessible to expert and non-expert audiences.  A high quality thesis is well organized, concise, grammatically and mechanistically correct, and coherent and logical in its arguments and development of ideas.  The written thesis must cite appropriate sources that inform the project.  Data must be clearly presented.  Language must be precise and sophisticated, with terminology appropriate for the topic of the thesis.

In the oral exam, the student must demonstrate both a mastery of the field and an understanding of the limitations of the research project and the limitations of the student’s own knowledge.  The student must be able to answer questions posed by the Honors Panel and engage with members of the Panel in a scholarly discussion of all facets of the project, including relevant background and supporting coursework.

Eleven graduate students—including one from the Department of Biology—have been selected for the final round of the inaugural Penn State Three Minute Thesis (3MT) competition. The final in-person round will be held at 10 a.m. on Saturday, March 23, both live-streamed online and in person at the Penn Stater Hotel & Conference Center. The event is free and open to the public, and advance registration is required.  

3MT is an academic research communication competition developed by the University of Queensland (UQ), Australia, that is now hosted at more than 100 universities worldwide. The Graduate School is hosting Penn State’s 3MT competition in partnership with the Graduate and Professional Student Association and the Graduate School Alumni Society. 3MT offers graduate students the opportunity to hone their academic and research presentation skills and their ability to effectively explain their research to a general audience while competing for prize money. Each student is allowed three minutes and one presentation slide to convey their work.

Sixty students from 42 graduate programs submitted videos as part of the first round of the competition, and a group of volunteer community judges evaluated the video presentations.  

The first-place prize for Penn State’s 3MT competition is $1,000, and the second-place prize is $500. A third prize, People’s Choice, is $500 and is sponsored by the Graduate and Professional Student Association. The People’s Choice Award will be selected by in-person and virtual attendees at the end of the final round.
