Updated: Feb 2023 | Biology Unit 2 Pure Biology Practical Assessment Scientific subjects are, by their nature, experimental. It is therefore important that an assessment of your knowledge and understanding of Science should include a component relating to practical work and experimental skills. This assessment is provided in Paper 3 as a formal practical test: Total: 40 marks, 20% of examination Duration: 1 h 50 min Although the questions are different on each Paper 3, the number of marks assigned to each skill is always the same. This is shown in the table below. Skill Description Weighting Planning (P) • Identify key variables for a given question • Outline an experimental procedure to investigate the question • Describe how the data should be used to reach a conclusion • Identify the risks of the experiment and state the precautions that should be taken to keep risks to a minimum 15% Manipulation, measurement and observation (MMO) • Set up apparatus correctly by following written instructions or diagrams • Use common laboratory apparatus and techniques to collect data and make observations • Describe and explain how apparatus and techniques are used correctly • Make and record accurate observations with good details and measurements to an appropriate degree of precision • Make appropriate decisions about measurements or observations 25% Presentation of data and observations (PDO) • Present all information in and appropriate form • Manipulate measurements effectively for analysis • Present all quantitative data to an appropriate number of decimal places/significant figures 25% Analysis, conclusions and evaluation (ACE) • Analyse and interpret data or observations appropriately in relation to the task • Draw conclusion(s) from the interpretation of experimental data or observations and underlying principles • Make predictions based on their data and conclusions • Identify significant sources of errors and explain how they affect the results • State and explain how significant errors may be overcome or reduced, as appropriate, including how experimental procedures may be improved. 35%

Updated: Feb 2023 | Biology Unit 3 1.Biological Drawing Here, we are training your observational skills. You should learn to look very closely at a specimen, and use sound Biology knowledge to choose the structures to include or omit in your drawing. A good biological drawing should… • Be drawn using a sharp 2B pencil • Cover at least 2/3 of space given • Have a clean, clear and sharp outline • Have straight labeling lines drawn using ruler (Ideally, labels should all be on one side of the drawing. Label lines also should not cross or obscure the drawing.) • Have labels for all features of the
