Design
|What to look for |Tick if correct | |Defines a FOCUSED problem or research question | | |Selects ONE independent variable | | |Selects ONE dependent variable which will vary (hopefully) as the independent variable is changed | | |Selects relevant and non trivial controlled variables | | |Equipment list of relevant apparatus giving size or range of equipment; | | |e.g. 250 cm3 beaker or thermometer -10 to 110 oC | | |Procedure explains how the independent variable is altered or changed (change at regular intervals is important) | | |Method gives way to collect sufficient dependent variable data (at least five), mention number of trials | |
