Key words

1.4 Things that have never been alive

• non-living • alive • living

Some non-living things were once alive.

These things come from plants and animals.

Wood comes from trees. We use wood for many things.

Trees are living but wood is non-living. When wood is cut from a tree it stops growing, so it is no longer alive.

Some things have never been alive, such as water, stone, metal and plastic.
