Sorting and Identifying Minibeasts
Using classification keys to identify minibeasts. Branching yes/no questions: 'Does it have legs?' → 'How many legs?' → 'Does it have wings?' Dichotomous keys as a systematic tool for sorting and identifying creatures.
What a learner can do afterwards
- Follow a simple branching key to correctly identify at least four different minibeasts
- Create a yes/no question that separates insects from spiders, such as 'Does it have six legs?'
- Explain why asking questions in a set order helps identify a creature you have never seen before

Scientists sort minibeasts by asking yes or no questions, one at a time, always in the same order. This list of questions is called a key. Each answer sends you down a different path until you find out what your minibeast is.
Mia finds a bug in the grass. She asks the key questions: Does it have legs? Yes. How many? Six. Does it have wings? Yes. The key tells her it is an insect, maybe a fly.
Always ask the questions in the same order: legs, then how many, then wings. If you jump around, you might guess wrong.
A key is a set of yes/no questions asked in the same order, and it can help you name any minibeast, even one you have never seen.
