The Scientific Method, Volume, Mass and Density Learning Goals

Upon the completion of this unit the student will be able to:

1. list and briefly explain the major steps of the scientific method.
2. define the term hypothesis
3. explain why increasing the number of trials of an experiment improves its validity. 4. list some factors needed for good experimental design.
5. identify the following in a controlled experiment; control, independent variable and dependent variable.
6. explain what is meant by experimental bias.
7. identify and state the function of the following pieces of lab equipment; mortar and pestle,safety goggles, beaker tongs, test tube holder, beaker, test tube, graduated cylinder, bunsen burner, burner stand and meter stick.
8. recognize the metric system works on powers of ten.
9. list and define at least six metric system prefixes.
10. be able to measure length using a metric ruler.
11. be able to measure mass using a triple beam balance.
12. define the terms weight, gravity and inertia.
13. state the freezing and boiling point on the Celsius scale
14. define the term volume.
15. explain how volume is measured in a graduated cylinder
16. explain how the volume of a rectangular block is calculated mathematically.
17. explain how the volume of an irregular object can be determined by water displacement.
18. define the term density.
19. perform density calculations given the mass and volume of a substance.
20. recognize that pure water has a density of 1.0 g/ cm3 and that objects less dense than water will float in it, while objects more dense than water will sink in it.
21. define the term matter.

Physical and Chemical Changes Learning Goals

Upon the completion of this unit the student will be able to:

1. define the term physical properties and list examples of these.
2. define the term chemical properties and list examples of these.
3. list and describe four phases of matter.
4. describe the relationship between volume and temperature with respect to gases.
5. describe the relationship between pressure and volume with respect to gases.
6. list two factors which may cause substances to change phase.
7. define the terms freezing, melting, evaporation, vaporization, condensation and sublimation.
8. identify freezing, melting, evaporation and condensation on a phase change diagram.
9. identify the regions of solid, liquid and gas on a phase change diagram.
10. explain the difference between physical and chemical changes and list examples of each.
