IB Biology Required Practicals Student Guides

Created by an IB Assistant Examiner, this 58 page BUNDLE of Required Practical Lab Guides provides full instructions for completing the IB Bio Required Practicals 1-7, with everything students need to complete the experiments, write their lab reports, and to practice the skills required for writing their Higher Level and Standard Level Internal Assessments (IB Biology SL and HL IAs).

IBDP Biology teachers can use this Required Practical bundle to assign their HL and SL students the IB Diploma Biology required practicals, as students are guided through the laboratory experiments and the writing of scientific investigations (lab reports) which meet the IB DP Assessment Criteria: Exploration, Analysis, Evaluation, and Communication.

These experiment guides have everything you need for your students to be successful completing their practice IB Bio Internal Assessments (IAs). No other resources are required (other than laboratory materials and equipment). Every year, Paper 3 Section 1 of the IB Biology Exam has included questions on these Required Practicals.

These practice investigations (lab guides) would also be suitable for any other High School Biology curriculum with a focus on scientific investigation and experiment lab report writing, such as Honors Biology or AP Biology.
