Practical Skills in Chemistry II

Independent Thinking and Use of Scientific MethodsSign up

solve problems set in a practical context · apply scientific knowledge to practical contexts · identify and state how to control variables to improve experimental validity · present data in appropriate ways · evaluate results and draw conclusions · appreciate measurement uncertainties and errors · comment on the method for an experiment

Numeracy and Mathematical Concepts in a Practical ContextSign up

plot and interpret graphs · process and analyse data using appropriate mathematical skills · use appropriate numbers of significant figures based on the experimental data · consider the accuracy and precision of data

Use of Apparatus and Equipment (Synoptic across the specification)Sign up

recognise a range of laboratory apparatus and select appropriate apparatus for a particular scenario · understand how to use a range of apparatus and techniques appropriate to the knowledge and understanding included in this specification · consider the range and resolution of apparatus · identify health and safety issues and discuss how these may be dealt with · recall and/or interpret observations relating to tests for ions and gases across the whole specification · recall and/or interpret observations relating to tests for organic functional groups across the whole specification · manipulate data and comment on experimental methods and techniques for a range of experiments involving measurements across the whole specification, including titrations, thermochemical investigations, equilibrium systems and kinetics experiments · comment on experimental methods and techniques in the preparation of inorganic or organic compounds across the whole specification
