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 EquipmentSign 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 in Units 1 and 2 · recall and/or interpret observations relating to tests for organic functional groups in Units 1 and 2 · manipulate data and comment on experimental methods and techniques for a range of experiments involving measurements in Units 1 and 2, including molar mass calculations, titrations, thermochemical investigations and simple kinetics experiments · comment on experimental methods and techniques in the preparation of inorganic or organic compounds in Units 1 and 2
