Then the teacher told the class that if the noise went over 90 decibels, they'd lose their break. They played along, testing how noisy they could be and watching the screen. They learned quickly, discovering things about graphs, measurement and keeping their break. The funding, called the GEST scheme, stretched to a few hundred schools who also discovered that you don't need to split atoms to use sensors. Since the scheme ran, and the money ran out, there are some new sensor kits and some for primary schools.
All kits have sensors which plug into a sensor box and then to the computer.
A laptop is handy, but any Windows, Acorn or Apple machine that uses menus and mice is best. You'll find the best among titles such as Insight, Junior Insight, Investigate, SoftLab, Datadisc and Datadisc Junior. Data Harvest's sensor box is called 'EasyLog'. For collecting readings away from the computer, the 'EasyLog' is very 'plug and play'. You plug in the sensors, press a button, and it will collect data until you're ready to stop.
