IB Biology Extended Essay (EE) Tutoring

Writing a 4,000-word EE in Biology requires strong research skills, scientific literacy, and structured academic writing. At IB Learning Star, our IB Biology EE tutors specialize in helping students navigate every stage of the Extended Essay journey—from idea conception to final submission.

The Biology EE allows students to conduct an in-depth scientific investigation, requiring the integration of theory, research, and experimentation. Our team ensures your research question is both original and practically viable.

IB Learning Star’s EE Support Includes:

Assistance in choosing a feasible, original research question that aligns with IB Biology syllabus content
Structuring the EE using proper scientific methodology (hypothesis, variables, data collection, analysis, evaluation)
Support with primary data collection and/or critical evaluation of secondary sources
Help in integrating relevant biology theories and models
Guidance on statistical analysis and interpretation (standard deviation, t-tests, chi-square tests, correlation analysis)
Critical review of drafts for clarity, scientific terminology, coherence, and rubric alignment
Academic honesty and proper citation mentoring (APA/MLA/Chicago formatting)

Sample Biology EE Topics:

Investigating water quality through indicator organisms
The effect of caffeine on Daphnia heart rate
Comparative protein concentration in plant-based milk alternatives
Antibacterial properties of essential oils versus commercial disinfectants
Rate of photosynthesis under varying CO2 concentrations
Effect of light spectrum on plant transpiration rates
Enzyme activity across different pH environments

Our IB Biology EE tutors have helped students across the globe secure A and B grades in their Extended Essays by offering consistent, constructive, and rubric-aligned feedback throughout the process.

TOK and IB Biology – Support from IB Learning Star

Biology often intersects with TOK themes such as ethics, objectivity, reliability of data, and the role of human interpretation in science. IB Learning Star's tutors are well-versed in guiding students to effectively integrate these conceptual intersections into their Theory of Knowledge essays and exhibitions.

We guide students in:

Linking IB Biology content to broader TOK knowledge questions
Evaluating the reliability of data and the objectivity of scientific methods
Discussing ethical implications of research and scientific experimentation
Comparing the natural sciences to other areas of knowledge
Using real-world case studies such as CRISPR, genetic engineering, and climate science

Our expert IB Biology tutors also help students:

Choose appropriate TOK exhibition objects related to Biology (e.g., lab reports, published scientific studies, medical equipment)
Frame compelling knowledge questions that explore how we produce and validate knowledge in biology
Reflect on limitations, uncertainties, and biases in biological knowledge production

Example TOK Knowledge Questions Related to Biology:

To what extent is scientific knowledge objective?
How do ethical considerations influence biology research?
Can scientific claims ever be completely free of bias?
How does the use of models in biology affect our understanding of reality?
In what ways does language influence how biological knowledge is communicated?
What are the implications of relying on statistical data in biological research?
How do paradigm shifts in biology (e.g., from Darwin to genomics) affect our view of the natural world?

IB Learning Star ensures students are not only prepared for their Biology assessments but are also confident in exploring cross-disciplinary links that elevate their TOK performance.
