Sensors help us to appreciate experiments in a different way. They allow to data to be collected over long or very short periods of time. They visualise changes that we don't normally see. The benefit is not really to do with getting a machine to do the work: it's more to do with gaining data we can use to make some learning happen. On the left are experiment ideas with questions to adapt to suit your objectives.
On a page nearby (Data handling) you'll find data from experiments that we collected over many years. You can use the data in Excel or your data logging program.
These experiments were contributed by
- Dr Laurence Rogers, Leicester University, the author of Insight (www.insightresources.co.uk). This software works with all sorts of data logging hardware.
- Roger Frost, writer on using computers in school science.
- Martin King, consultant and former head of science.
- The Schools Online project at Sheffield Hallam University.
