Pet Identification Key Worksheet
How keys work
A branching identification key narrows down the possibilities one step at a time. Each question should have two clear answers, such as “yes” and “no”.
- To identify an organism using its features
- To explain how to look after a pet
- To count how many organisms are in a habitat
- To describe what an organism eats
- Is it a goldfish?
- Does it have feathers?
- Is it friendly?
- Does it have a name?
- Has feathers
- Has scales
- Is the nicest pet
- Has fur
- Is somebody’s favourite
Follow the key
Use these pet facts: the budgie has feathers and wings; the goldfish has fins and scales and lives in water; the dog and cat have fur and four legs; the dog has a long muzzle and the cat has a short muzzle; the hamster has fur and four legs and is much smaller than the dog and cat.
Build and test a key
Use the facts above to create a key that identifies all five pets. Each question should split the remaining pets into two groups. Finish with one pet at each endpoint.
