IB Biology consists of two components – Final exam and Internal Assessment (IA).
The final exam comprises 80% of the entire grade while the IA comprises 20%.
Two years of work is provided for Biology IA. To get the advantage of it, expert IB Biology SL tutors suggesting the way on how you can get a 7 on your Biology IA.
About Biology IA
Biology IA consists of a 6-12 page long research paper on the topic you choose.
It follows the rigid structure, including:
Introduction
Background Information
Hypothesis
State the hypothesis and give a logical rationale.
4. Variables
Create a chart or list – identifying the Independent, Dependent, and Controlled Variables.
5. Photograph of lab setup
Annotate this to show how variables were instituted – specifically the controlled variables.
6. Procedure
Write in numbered, bulleted list for, passive voice, and read like directions.
Must include:
At least 5 independent variable “intervals”.
Minimum 5 repeat {trials}.
Collect qualitative data (in a numbered, titled data table)
7. Data collection and Processing
Raw Data Table:
Ensure this is raw data only, and it’s all columns are properly headed with units given.
Do not split the data table and if you do, ensure to redo the title and column headings.
Create one table including 5 independent “intervals”, instead of making 5 separate ones.
Qualitative data table:
Must be numbered, titled with appropriate labels.
That’s observation so don’t mention “number” data.
Overview:
Include overview of how and why of the process
Sample Calculation:
Layout and explain one example of any type of manipulation done to the raw data.
Processed Data & Graphs:
Must have the design and clarity of data tables
Quality of graphs
Ensure to follow good standard rules for doing graphs
8. Conclusion and Evaluation: Limitations and Suggestion
Conclusion:
Discuss the results of your experiment.
Address whether the data supports or refutes the hypothesis.
Avoid using words – “proof” or “proves”
Limitations of Experimental Design:
What worked well (and why)
What did not work well (and why) – mention 3 limitations
Results of the test (if statistical test)
If errors on your graph(s) – what do these show?
Suggestions for Improvement:
As per the limitations included above, to suggest realistic and useful improvements – it must show good reflective thinking.
Along with suggesting all these, exceptionally trained IB Biology HL tutors, suggested few more tips to follow:
Framing your RQ
Personal Engagement
Presentation and format
Data Collection
