1.2 How science works – Practical and enquiry skills

click1.2e Working critically with primary evidence |
| spot patterns and trends in results, e.g. spot the link between the load on a spring and the extension produced | explain whether evidence is sufficient for a sound conclusion, e.g. whether the force meter readings when stretching polythene in different directions are sufficient to assert whether or not the difference is significant |
| recognise the connection between prediction made and results obtained, e.g. look at the observations made on a series of chemical reactions and go back to the prediction to see if the reasoning suggested is supported | recognise that error and uncertainty can affect the reliability of readings and how this could lead to incorrect patterns being identified or justified |
| describe key features of planning and implementation, e.g. identifying the variables in an experiment to investigate a vehicle rolling down a slope and deciding which to vary, which to keep constant and which should be measured as an outcome | identify whether or not a pattern supports a prediction, e.g. say whether or not evidence about the reactivity of metals going down a particular group in the periodic table supports a prediction made |
| | describe deficiencies in the plan and implementation, e.g. if energy being released by burning a fuel is to be measured by being absorbed by a boiling tube of water above it |
