Students vary the factor and measure the rate of respiration. Experiments fully specified in terms of equipment and method. Teacher allows a limited choice of factors to be varied. Students vary the factor and measure the rate of respiration. Experiment probably specified by teacher. Teacher allows a choice of factor. Students have a number of experimental procedures to choose from, and then follow that procedure. Student decides on a question. Student researches methods for carrying out the experiment then chooses equipment, 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. Students must correctly use the appropriate equipment. Students must correctly use the appropriate equipment. Students must choose an appropriate approach, equipment and 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. and records observations Students record measurements in specified Students record measurements Students record measurements in specified Students must choose the most effective way of recording
