Trees are cool because:

• Trees make oxygen and cool the air

• Trees are beautiful

• Trees have many different kinds of leaves

• Trees make good homes for animals

• Trees are good to climb on

• Trees can be used for lumber and paper

• Trees absorb pollutants and help to control erosion from stormwater

Now change "tree" to a different word every time and see how odd it can be. My friend and I changed it to clocks and cats. Very entertaining. Let me know what words you use.
