EOWL 8: Physical/Chemicl Properties
	Exceeds 4 pts	Meets 3 pts	Nearly Meets 2 pts	Does Not Meet 1 pts
Name four physical properties	Exceeds Names more than four OR identifies them as characteristic or non-characteristic	Meets Names four physical properties such as color, odor, density and solubility (characteristic), or mass, volume, shape and texture (non-characteristic).	Nearly Meets Names less than four correctly.	Does Not Meet Attempts to answer the question.
Name two physical changes	Exceeds In addition, gives an example OR identifies them as having to be non-characteristic physical properties.	Meets Names two physical changes such as a change in mass, volume, shape or texture.	Nearly Meets Names only one correctly. Incorrect answers could be "change in color", "change in odor".	Does Not Meet Attempts to answer the question.
Difference b/w phys. prop & change	Exceeds In addition, identifies the phys. props. as having to be non-characteristic.	Meets "Phys. prop. can be measured w/o changing the identity of the substance. Phys. change occurs when a phys. prop changes and the substance stays the same."	Nearly Meets Defines only one of the two correctly, OR does not state "w/o changing the identity of the substance".	Does Not Meet Attempts to answer the question.
How temp. affects solubility?	Exceeds In addition, describes the motion of molecules (kinetic energy) as increasing.	Meets "As temperature increases so does solubility."	Nearly Meets Identifies temperature as affecting the state of matter (solid, liquid, gas). Does not refer to solubility.	Does Not Meet Attempts to answer the question.
Interaction of molecules dissolving	Exceeds In addition, identifies the attraction between molecules as being that between negative and positive regions of the different molecules (polarity).	Meets "Molecules of water are attracted to molecules of sugar. The water molecules wedge apart the sugar molecules and surround them. This is a physical property."	Nearly Meets Misidentifies as chemical property. OR Does not describe molecules interacting.	Does Not Meet Attempts to answer the question.
