A program called a 'branching database program' allows you to make a identification 'key'. Our Internet animal game is a taster of how using a key gets people thinking. You might use such a database to sort out plants, trees, fruits, animals, elements or household chemicals. It's a 'collaborative' exercise and the pupils' discussions are good to hear. We'd recommend you use one. 

Primary schools might appreciate this note on how to run the activity. See also the worked examples on branching database programs in IT in Primary Science and IT in Secondary Science.    


The favourite is:
