IB Biology Required Practical 2 - Osmolarity - By an IBDP Assistant Examiner

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.

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)

This IB Required Practical is part of IB Biology Topic 1 (Cell Biology), specifically Subtopic 1.4: Membrane Transport. Please check out my Google Slides presentation which includes everything you need to teach the content of this subtopic.

Also suitable for other curriculum programs - any kind of High School Biology course that focuses on scientific inquiry, such as AP Biology or Honors Biology.

As an IBDP Assistant Examiner with 27 years experience teaching IB Diploma Biology and IB MYP Science, I have created multiple resources which I am uploading to TpT now: Standard Level and Higher Level IB Biology lessons and presentations, required practicals, as well as entire units and unit plans. Check out Power Of Science, my TpT store, to see more. If you click 'Follow Me', you'll be notified whenever I add more products. I will be adding many more International Baccalaureate Diploma Programme Biology resources for both Standard Level and Higher Level IB Bio.
