ASE Evaluated Product

The English National Curriculum states that pupils should ‘work scientifically’ by ‘taking measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate, recording data and results of increasing complexity using scientific diagrams and labels, classification keys, tables, scatter graphs, bar and line graphs‘. 

This is very much supported by the EasySense Vu data logger. If you have not yet invested in a set of data loggers then the EasySense Vu offers a good solution.
