A practical guide to the individual scientific investigation in IB Physics, Chemistry and Biology.
In IB Physics, Chemistry and Biology the internal assessment is an individual scientific investigation. You choose a question, plan and run an experiment or analyse data, and write it up for assessment against the criteria.
Your teacher marks it and the IB moderates a sample.
A good question names a variable you change, a variable you measure and a context you can control. Check that you can collect enough data with the equipment and time you have.
Process the data with a method that suits the question, present it in a clear graph and explain what it shows. Then evaluate: what limits the result, and what would improve the investigation next time?
Strong evaluations are specific, not general.
Each subject has an individual scientific investigation assessed against criteria, with some differences in detail. Check your subject guide.
One that is focused, testable and possible with the equipment and time you have.
A tutor can help you plan and review. The investigation and the write-up must be your own.
