Physical vs. Chemical Changes & Properties
I. PHYSICAL PROPERTIES: Density
Go to http://phet.colorado.edu/sims/density-and-buoyancy/density_en.html and explore density of different materials, the same material of different sizes, and guess the mystery objects!
Record your conclusions about density on the sheet provided by your teacher.
II. PHYSICAL CHANGES: Reversible or Irreversible?
Try to dissolve different substances in water. Then heat ice to melting and cool it back down to freezing again - a REVERSIBLE change. Then take the QUIZ.
Raise your hand to call the teacher over to see your score when you're done with the quiz!
