Teacher chooses the microbe and antimicrobial substance(s) to be investigated. Students prepare agar plates with the microbe and antimicrobial substance(s) and measure the outcomes. Experiments fully specified in terms of equipment and method. Teacher allows a limited choice of antimicrobial substance(s). Students prepare agar plates with the microbe and chosen antimicrobial substance(s) and measure the outcomes. Experiment probably fully specified by teacher. Teacher allows a choice of microbe and antimicrobial substance(s). Students have a limited number of experimental procedures to choose from, and then follow that procedure and measure the outcomes Student decides on a question. Student researches methods for carrying out the experiment then chooses equipment and materials, justifying all choices. Opportunities for observation and assessment of competencies Follow written procedures Students follow written method. Students follow written method. Students follow a method they have chosen. Students follow a method they have researched. Applies investigative approaches and methods when using instruments and equipment Students must correctly use the appropriate equipment and aseptic technique. Students must correctly use the appropriate equipment and aseptic technique. Students must correctly use the appropriate equipment and aseptic technique Students must choose an appropriate approach, equipment and aseptic techniques and identify correct variables for measurement and control. Safely uses a range of practical equipment and materials Students must safely use the equipment. Students must safely use the equipment. Students minimise risks with minimal prompting. Students must carry out a full risk assessment and minimise risks. Makes and records observations Students record observations in specified ways Students record observations in specified ways Students record observations in suitable ways. Students must choose the most effective way of recording observations Researches, references and reports Students compare results with published data and identify reasons for differences. Students compare results with published data and between students and identify Students compare results with published data and between students and Students must research alternatives in to plan their work. Reporting covers the planning, carrying out and an analysis of their results.
