Unit 3: Living things

What makes something alive, how living things grow, move and reproduce, and how scientists sort them.

• 3.1 Living and non-living – Is a flame alive? Is a seed? How can you tell?
• 3.2 Growth and nutrition – All living things grow – but they need food to do it.
• 3.3 Movement and reproduction – How do living things move – and make more living things?
• 3.4 Sorting humans – We are all humans – but no two people are exactly the same.
• 3.5 Sorting living things – Scientists sort millions of living things into groups.
