H11 justifies the appropriateness of a particular investigation plan 11.1 identify data sources to: a) analyse complex problems to determine appropriate ways in which each aspect may be researched b) determine the type of data that needs to be collected and explain the qualitative or quantitative analysis that will be required for this data to be useful c) identify the orders of magnitude that will be appropriate and the uncertainty that may be present in the measurement of data d) identify and use correct units for data that will be collected e) recommend the use of an appropriate technology or strategy for data collection or information gathering that will assist efficient future analysis 11.2 plan first-hand investigations to:  a) demonstrate the use of the terms ‘dependent‘ and ‘independent‘ to describe variables involved in the investigation b) identify variables that needed to be kept constant, develop strategies to ensure that these variables are kept constant, and demonstrate the use of a control c) design investigations that allow valid and reliable data and information to be collected d) describe and trial procedures to undertake investigations and explain why a procedure, a sequence of procedures or the repetition of procedures is appropriate e) predict possible issues that may arise during the course of an investigation and identify strategies to address these issues if necessary 11.3 choose equipment or resources by: a) identifying and/or setting up the most appropriate equipment or combination of equipment needed to undertake the investigation b) carrying out a risk assessment of intended experimental procedures and identifying and addressing potential hazards c) identifying technology that would be used during investigation determining its suitability and effectiveness for its potential role in the procedure or investigation d) recognizing the difference between destructive and non-destructive testing of material and analysing potentially different results from these two procedures H12 evaluates ways in which accuracy and reliability could be improved in investigations 12.1 perform first-hand investigations by: a) carrying out the planned procedure, recognising where and when modifications are needed and analysing the effect of these adjustments  b) efficiently undertaking the planned procedure to minimise hazards and wastage of resources c) disposing carefully and safely of any waste materials produced during the investigation d) identifying and using safe work practices during investigations
