click1.2b Using investigative approaches: selecting and managing variables |
| identify relevant variables in an investigation, e.g. identify what would affect the rate at which a trolley rolls down a slope and therefore which variables to alter and which to keep the same | correctly identify the different variables in an investigation and whether the dependent variable may or may not be affected by the independent variable, e.g. would seed germination be affected by the size or colour of the container? |
| list all the variables and make sensible choices about the dependent and independent variables, e.g. when investigating the effect of indigestion powders realise that colour of powder would not be a sensible choice | assign appropriate values to variables, e.g. select an appropriate range of masses sufficient to stretch a spring without causing permanent deformation |
| explain the difference between independent and dependent variables, e.g. articulate their own way of remembering the difference between the two | |
