Summary

Using classification keys

In a nutshell

Scientists use classification keys to identify unknown plants and animals. A key involves a series of questions about the features of the plant or animal. Each question has two answers, one answer will take you to the next question and the other will reveal the unknown plant or animal.


Example 

Here is a classification key. 

Science; Living things and their habitats; KS2 Year 4; Using classification keys


Science; Living things and their habitats; KS2 Year 4; Using classification keys
We will identify this unknown creature.


PROCEDURE

1.
Starting at the top of the key, answer the first question.
2.
Our creature does not have wings so we choose 'no' and move on to the next question.
3.
Our creature does not have gills, so once again we choose 'no' and move on the next question.
4.
Our creature does not have scales - it must be a fox!
