** Study your notes packet, handouts, textbook & labs completed**

1. Be able to define, explain & give examples of the following terms: a. matter b. mass vs weight c. energy (kinetic & potential) d. parts of Sci. Method e. inference f. hypothesis g. theory h. model i. errors (random & systematic) j. element k. compound l. mixture (homogeneous vs heterogeneous) m. physical vs chemical property n. physical vs chemical change

More Terms: o. Intensive vs extensive properties p. separation q. decomposition r. Laws of conservation (mass, energy, mass & energy) s. endothermic vs exothermic reactions t. accuracy vs precision Qualitative & quantitative Etc.

General Skills: 2. Be able to write a small or large number in scientific (exponential) notation. 3. Identify the 7 base SI units. (quantity, unit, symbol) 4. Define and give examples of derived units. 5. Know the metric prefixes and their values. (Memorize giga – nano)

6. Be able to convert metric units. 7. Know the rules for identifying the number of significant figures in a measurement. Be able to round calculations to correct number of significant figures. (Multiplication/Division;Addition/Subtraction) 8. Calculate the % error for an experiment.

9. Complete density problems. (Find density, mass, or volume) 10. Identify physical or chemical properties & changes. 11. Identify common properties of metals, nonmetals, metalloids. 12. Identify properties of the states of matter (solid, liquid, gas)

Distinguish between Elements, Compounds and Mixtures. Explain how the law of conservation of mass is true in chemical reactions.
