IB Biology IA Source Checker

Biology IA can use primary or secondary biological data, but the source must support real analysis and allow limitations, uncertainty, ethics, and biological relevance to be discussed.

Biology IA

What usually works for Biology IA

Usually strong

  • Student-collected experimental or observational biological data.
  • Reliable public biological datasets, ecological databases, gene/protein databases, or government health/environment data.
  • Peer-reviewed studies used to justify method, variables, or biological context.

Example

A student-collected enzyme rate dataset with repeats, uncertainty, and controlled variables.

Needs a second look

  • Datasets with no collection method or unclear units.
  • Human-participant or organism work without consent, welfare, or safety planning.
  • A source that only explains biology concepts without providing usable evidence.

Example

A public ecological dataset with good values but limited information about sampling method.

Avoid or replace

  • Unverified AI-generated datasets.
  • Unsafe culturing, invasive organism work, or medical claims beyond school lab scope.
  • A copied classic practical with no adapted variable or context.

Example

A revision webpage explaining photosynthesis.

Where to find better Biology IA sources

If a source gets a warning, don't just add more websites. Search for sources that match the assessment rule and can carry real analysis.

Searches to try

If a source is weak

  • Replace unverified ai-generated datasets. with student-collected experimental or observational biological data..
  • Use datasets with no collection method or unclear units. only as context unless your teacher confirms they can carry evidence.
  • Add one source that gives direct evidence for the IA, not just general background.

Good places to look

  • Student-collected experimental or observational biological data
  • Reliable public biological datasets, ecological databases, gene/protein databases, or government health/environment data
  • Peer-reviewed studies used to justify method, variables, or biological context
