Practical Skills in Biology II
Practical Skills in Biology II — Edexcel International A-Level Biology (Unit 6, IA2). Externally assessed skill unit that builds on Unit 3 by applying experimental procedures and techniques to investigations linked to Units 4 and 5. Includes planning whole investigations, analysing data, and evaluating methodology.
Planning Whole InvestigationsSign up
plan a complete experimental investigation to test a hypothesis, including apparatus, variables, control, safety, and how the data will be used · identify sources of uncertainty and systematic error; discuss how to reduce or eliminate them · comment on the wider implications and context (social/environmental/historical) of the investigation
Practical Techniques for Units 4 and 5Sign up
apply techniques from Unit 4 (photosynthesis rates, ecological sampling, microbial growth, antibiotic testing) and Unit 5 (respiration, kidney/spirometry, microscopy) to novel contexts · evaluate the choice of apparatus and method for the technique in use
Synoptic Data Analysis and EvaluationSign up
process and analyse data using appropriate mathematical skills, including ratios, exponential and logarithmic functions, and statistical tests · evaluate results and conclusions with reference to measurement uncertainties and errors; suggest realistic modifications · draw together evidence from multiple topics to answer synoptic questions
