Identifying organisms

Identifying organisms can be challenging, particularly when there could be hundreds of different species within any one sample. Scientists use paired-statement keys to make it easier to identify organisms that are sampled.

Paired-statement keys are set out as a list and you simply start at number one on the list and work your way through until you reach the name of the organism.

Below is a simple paired statement key for garden invertebrates. Pick one of the organisms and work your way through the flow chart to identify it.

A yes no flow chart that deciphers whether the user is thinking of an ant, beetle, spider, worm or snail.
