Song on physical or chemical changes

Find out the major differences between physical and chemical properties of matter. Do you remember the song, "Oblah-Di Oblah-Da?" If so, this will be easy to sing. Words and Chords are in "Docs" section on TeacherTube for "dsecms". OR BELOW:
The Properties Song: (Melody based on the song,
"Ob-La-Di, Ob-La-Da" by John Lennon and Paul 
McCartney) Lyrics by Doug Edmonds

Physical and chemical properties,
Help to tell what matter's all about.
All you have to do is know some simple facts,
That will help you separate the two apart.

What you see, what you hear, what you smell, yeah!
That's physical, your senses tell you so.
Can you measure the matter in some way?
That's physical for sure! Oh, by the way ...

Color, odor, size and state and boiling point, 
Or melting point or good ole' density,
And don't forget there's also solubility,
All of these physical properties that be.


But chemical properties are different.
They help us see if substances will change,
When they meet another substance in their way.
Their atoms may decide to get all rearranged!


Physical and chemical changes
