Lab protocols for new IB guide

Seven prescribed experiments

There are seven experiments which are prescribed by the new biology guide.

An understanding of these experiments will be assessed in the new first section of paper 3 on experimental skills.
Students will therefore need to have hands on experience of these experiments in particular. It is expected that short answer, structured questions will assess the skills to carry out the experiments, analyse the data and evaluate the results
