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.
Lesson
Set out your lesson
“A branching key asks one question at a time. Each answer chooses the next branch. It works only for the organisms and features it includes. Our four-card key is not safe for naming every unknown animal; missing observations require an uncertain answer. Safety: No collection, handling or species-safety decisions. Stop: Stop when the four cards and one uncertain card are checked. Do not collect animals to use the key.”

Extra for the adult
Worked example. For the snail: Q1 no → Q3; Q3 yes → snail. The shell plus the no-leg observation fits that card. For legs not visible, Q1 cannot be answered, so the correct result is not enough evidence, not no legs.
Optional challenge. Why would a centipede with many legs fail this limited four-card key? Adult key: A centipede has more than six or eight legs and falls outside the key’s listed choices, so its label must remain unresolved.
What to notice. Keep the key and route log. Note questions read aloud or branch choices supplied by an adult.

Check understanding
- 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
“If your child found an unfamiliar minibeast, could they use a set of yes/no questions — like 'Does it have legs? How many?' — to work out what group it belongs to?”
