Let's separate these amphibians into two football teams.
Well we're just about to have a frog vs toad football match.
Hang on鈥ou two!
Which teams are you supposed to be playing for?
What, you don't know if you're toads or frogs?
Hmmm.
You do look quite similar.
Well we're going to have to use classification keys to tell which is which鈥
No! I don't mean an actual key.
Classification keys are questions that let us find out which groups living things belong to.
Like this鈥s your nose pointy or blunt?
Pointy鈥ell you might well be a frog.
Blunt鈥ou might well be a toad.
Let's use another question.
Do you like jumping, or walking?
Well now I'm almost sure you're a frog.
What about you?
And I'm almost sure you're a toad.
What about your skin?
Is it bumpy and dry?
Good! Well you're playing for Toad United!
And is your skin smooth and a bit wet?
You're playing for Frogchester then!
Off you go!
Classification keys
A key is a set of questions about the characteristics of living things.
You can use a key to identify a living thing or decide which group it belongs to by answering the questions.
