4. Viscosity
Resistance to flowing Can vary with temp.
Qualitative

5. Conductivity
The resistance to flowing of heat
Can vary with temp.
Quantitative

6. Malleability
The ability of a solid to be hammered without shattering
Qualitative

7. Hardness
Comparative test between two
objects to see which one will
scrape the other
Qualitative

8. Odor
What something smells like
(remember to waft)
Qualitative

9. Classifying Matter
A Mixture or Pure Substance?

10. Matter
Pure Substance Mixture
Element Compound Homogeneous
Heterogeneous

11. Mixtures
Two or more substances that are not
chemically combined with each other and
can be separated by physical means. The
substances in a mixture retain their
characteristic properties.

12. Element
Simplest form of pure substance. They
cannot be broken into anything else
by physical or chemical means.

13. Compound
Two or more pure substances (elements or
compounds) chemically combined that do
not retain their characteristic properties.
They can be broken into simpler substances
by chemical means.

14. Chemical Changes

15. Change in color
Change in color is a clue that the matter has produced at
least one new substance.

16. Production of gas
When to substances are put together and they release
bubbles/gas, it has made a chemical change.

17. Formation of a
precipitate
Any solid that forms a liquid mixture is called a precipitate.

18. Name 6 physical
properties

19. What is a colliod?

20. Whats the difference
between a
heterogeneous mixture
and a homogeneous
mixture?

21. What is the smallest
particle of an element?

22. Will a chemical change
occur if a Mento is put
into carbonated water?
If so what type or
types?

23. Bonus
Will a banana explode
if it is thrown in a large
body of water?
