Research Project Ideas in Biology for High School Students
Specific, answerable questions across genetics, physiology, ecology, and evolution, with guidance on doing genuine biology research without a laboratory.
How to Use This List
Biology tempts students towards enormous topics, cancer, evolution, climate, that no single project can address. The questions below are deliberately narrower, because a focused question you can genuinely answer demonstrates far more than a sweeping one you can only summarise.
Treat each as a starting point to refine further. The strongest school-level biology projects are usually literature reviews or analyses of existing data rather than original experiments, which raise practical and ethical hurdles. Our guides to writing a research question and writing a literature review show how to build one well.
Ideas by Sub-Field
Genetics & molecular biology
- ↳ Is CRISPR-based gene editing a proportionate response to hereditary disease, and who should decide?
- ↳ What does the evidence say about how a specific environmental factor influences gene expression?
- ↳ How has our understanding of "junk" DNA changed, and what is its function now thought to be?
Physiology, disease & the microbiome
- ↳ To what extent does gut-microbiome diversity predict antibiotic response in adolescents?
- ↳ How does the immune system distinguish self from non-self, and what happens when it fails?
- ↳ What does the research reveal about how chronic stress measurably affects the body?
Ecology & the environment
- ↳ How does habitat fragmentation affect biodiversity in a specific ecosystem, according to existing studies?
- ↳ What can open biodiversity datasets reveal about the effect of climate change on a chosen species?
- ↳ How effective are rewilding interventions, and how is that effectiveness measured?
Evolution & behaviour
- ↳ What evolutionary explanations exist for a specific human or animal behaviour, and how testable are they?
- ↳ How does antibiotic resistance evolve, and what does that imply for how we use antibiotics?
- ↳ What does the evidence say about convergent evolution in unrelated species?
Where to Find Evidence
A literature-based biology project lives or dies on its sources. PubMed is the essential database for biomedical research; the editorials and reviews in journals such as Nature and The Lancet are accessible entry points to a field. For data-driven work, open repositories, from biodiversity records to public-health datasets, allow genuine analysis without a laboratory.
The skill a mentor most often teaches here is critical reading: distinguishing a strong study from a weak one, noticing when a headline claim outruns its evidence, and synthesising findings that do not entirely agree. That skill is the heart of university biology, and of medicine.
Taking a Question Further
Biology shades naturally into medicine, neuroscience, environmental science, and ethics. For the wider context, see our Medicine & Life Sciences field page, our companion guide to research project ideas in neuroscience, and our broader research project ideas across all six fields. When you are ready to turn a question into a finished project with a mentor who works in the field, the Research Scholar programme is built for exactly that.
Frequently Asked Questions
Can I do a biology research project without a laboratory?
Yes. Most strong pre-university biology projects are literature-based or use existing public data rather than original wet-lab experiments. Synthesising research on a focused question, or analysing open biological and health datasets, is genuine science and needs no lab.
Do I need to have studied A-level Biology or equivalent?
No. Curiosity and a willingness to read demanding material matter more than prior coursework. A mentor builds the necessary background as part of the project, and students often do their best work in an area they had not formally studied at school.
Is a biology project good preparation for medicine applications?
Yes. A focused project in physiology, genetics, microbiology, or public health demonstrates exactly the research literacy that medicine and biomedical degrees demand, and gives a medicine applicant something specific and genuine to discuss at interview.
What makes a biology research question strong rather than too broad?
A strong question is narrow enough to answer with the sources or data available. "How does diet affect health" is too broad; "what does the evidence say about the link between gut-microbiome diversity and antibiotic response in adolescents" is a question you can actually investigate.
Summer cohort deadline · Applications due June 25. A few places remain. We assess applications in order of receipt.
ScholarBridge matches students with doctoral-level or equivalent research mentors across six academic fields. Every project is student-led and completed to a standard the student can stand behind in any university interview.
