Biology: Chapter 2, lesson 1: Living and Nonliving Things
 You can tell a living thing from a nonliving thing by observing its properties.
 Property = a quality that describes an object.
 Can describe how an object looks or feels.
 Can describe how an object behaves or acts.
 All things have different properties from another thing.
 Properties of Nonliving Things
 They have properties that you can see and feel.
 How hard is it? What color is it? What shape or size is it?
 Properties that nonliving things have:
 They do not carry out all of the basic life activities.
 It might carry out one or two but not all of them.
 Sugar crystals can grow but they don’t do other activities.
 They are not made of cells.
 Properties of Living Things
 They have properties you can see and feel.
 How hard is it? What color is it? What shape or size is it?
 They carry out all of the basic life activities.
 Living thing = organism= a complete, individual living thing.
 Example= you, a tiger, a butterfly, a bacteria, a pine tree.
 It carries out all basic life activities.
 Organ in organism = “tool” in Latin.
 A tool does a certain job; an organ does a certain job in a living thing.
 Organs are organized tissues and cells that carry out basic life activities.
 Examples: heart, lungs, stem, leaves.
 Simple organisms don’t have organs.
 Some have organelles – like organs but they are inside the cell and they do a
particular job.
 Bacteria – the simplest organism – don’t have organelles.
