'''Data logging''' is the process of recording measurements from sensors. A weather station pretty well fits this definition. The station captures readings from sensing devices and it may also display what is happening right now. The station offers such a better way to study the world. | '''Data logging''' is the process of recording measurements from sensors. A weather station pretty well fits this definition.

In short data logging offers ways to do core science experiments, such as study insulating materials; or acceleration of a trolley on a ramp; or electromagnetic induction. But it also offers a strategy to have good investigative science happen in schools.

Data Handling: | |||
When you first come to use the technology like this, using the technology to take the science further, using it to quantify differences; to derive data and to model it, may well seem a long step ahead. However, making use of data so expensively collected, really deserves to happen in mainstream teaching. When you see the need, it will help to know there are data handling packages designed for use with data collected from sensors. One might imagine that a spreadsheet could handle this - however, these data handling packages can take readings at points on a graph; calculate net changes; calculate graph areas; plot a rate of change against time; fit this to a model and more. | |||
