equipment can be used to observe, generate, measure and record data with reasonable precision for repeated measurements, using digital tools as appropriate

• recording data using standard units such as the volt, ampere, gram, second and metre, and developing the use of standard prefixes for metric units, such as ‘kilo-’ and ‘milli-’
• using digital tools such as digital thermometers and soil moisture probes to collect data over time, and recording data in spreadsheets
• discussing why precision is important in measurement, and comparing the precision of different class data sets, for example the growth of radish seeds in different soil environments and the length of shadows at different times of the day
