1. Physical Property: Describes a substance’s appearance.
Chemical Property: Describes how matter reacts to change into other chemically different substances.

2. Clues that a Chemical Change has taken place:
Formation of a gas
Formation of a precipitate (solid)

A change in color

3. Color Change & Solid Forming

4. Gas Forming

5. Temperature Change

7. Concrete

8. Saltwater
Homogeneous mixture

9. Soil
Heterogeneous mixture

10. Neon
Element

11. Sugar Sucrose C12H22011
Compound

12. Write the type of matter for each:
Sweat from a football player’s armpit
(answer: homogenous mixture – salt and water mixes evenly)
Hydrogen peroxide that you put on oozing cuts (ans: compound)
Vanadium (it’s on the periodic table) (ans: element – if its on the periodic table…)
Vomit with chunks of your dinner in it
(ans: heterogeneous – not an even mix)

14. Intensive Extensive What’s the same? What’s different? Color Density
Ductility
Malleability
Conducts Electricity
