Created by an IB Assistant Examiner, this 12-page Lab Guide provides full instructions for completing the IB Required Practical 3 (Enzyme Experiment), with everything students need to the practice skills required for writing their Internal Assessment (IA). IBDP Biology teachers can use this enzyme experiment guide to assign their SL and HL students the IB required practical, as it guides students through the laboratory experiment and the writing of a scientific investigation (lab report) which meets the IB Assessment Criteria: Exploration, Analysis, Evaluation, and Communication. Skill: Experimental investigation of a factor affecting enzyme activity. This experiment guide has everything you need for your students to be successful in their IA. No other resources are required (other than laboratory materials and equipment). This would also be suitable for any other High School Biology curriculum with a focus on scientific investigation, such as Honors Biology or AP Biology. Features: Links to IB Assessment Criteria and Rubrics Key Terms Organised with clear subheadings (using IB Assessment Criteria) Easy to Follow Tips for success with IB Biology Internal Assessment Bullet Points for clarity Sample data tables Clear Instructions for writing a lab report (scientific investigation)

Created by an IB Assistant Examiner, this 8-page Lab Guide provides full instructions for completing the IB Required Practical 2 (Osmolarity Experiment), with everything students need to the practice skills required for writing their Internal Assessment (IA). IBDP Biology Teachers can use this experiment guide to assign their students the IB required practical, as it guides students through the laboratory experiment and the writing of a scientific investigation (lab report) which meets the IB Assessment Criteria: Exploration, Analysis, Evaluation, and Communication. Skill: Estimation of osmolarity in tissues by bathing samples in hypotonic and hypertonic solutions. This document has everything you need for your students to be successful in their IA. No other resources are required (other than laboratory materials and equipment). This would also be suitable for any other High School Biology curriculum with a focus on scientific investigation.

Created by an IB Assistant Examiner, this 7-page Guided Practice with microscopes and magnification provides full instructions for completing the IB Required Practical 1 (Using Microscopes, and Magnification Calculations). Includes sample problems to prepare your students for IB Biology Exams. IBDP Biology Teachers can use this Guided Practice to support DP Bio SL and HL students as they: Prepare and view microscope slides of onion cells and human cheek cells (i.e. plant and animal cells). Solve magnification calculations using the included images with scale bars and rulers, the magnification formula, and the step-by-step problem-solving process. Skills (from IB Biology Guide): Use of a light microscope to investigate the structure of cells and tissues, with drawing of cells. Calculation of the magnification of drawings, and the actual size of structures and ultrastructures shown in drawings or micrographs. This Guided Practice has everything you need to prepare your students to be ready to answer the many magnification questions on IBDP Biology Examinations. This would also be suitable for any other High School Biology curriculum with a focus on scientific investigation, such as AP Biology or Honors Biology. Features: Key Terms Links to helpful videos Clear subheadings and sections Bullet Points for clarity Printable Ready to use Five Practice Questions with guided steps Useful unit conversions Clear illustrations with rulers and scale bars Complete Answer Key
