Change

Change…It’s everywhere you go Change…It may be fast or may be slow

Change…There’s no way to deny it But at least you can learn to classify it

Put a can of cola in the freezer The water in the cola turns to ice +

It pushes on the can and may explode Cleaning up that mess is not so nice

Now ice seems different than water But its true identity’s the same What do you say when you see this kind of thing?

You call it physical change

Light a match and start a candle burning See how it gives off heat and light

Don’t stick your finger in that hot wax People who do that aren’t too bright

The wax is doing more than melting It’s atoms move around and rearrange CO2 and water are produced when it burns

You call that chemical change

So what kind of change is “iron rusting” Or when a leaf turns from green to red?

What’s going on when you grind a rock to dust Or when you’re growing hair on your head?

What kind of change is “paper burning” Or when you hammer metal into foil?

What happens when you put an alka seltzer tablet on your tongue Or when you make a pot of water boil?
