Metrics, Measurement, Safety and the Scientific Method Test Review – Periods 4 & 5 1. Know the metric prefixes giga, mega, kilo, centi, milli, micro and nano. Know the symbols and values (powers of ten) that correspond to each prefix. Be able to convert between metric units, including area and volume measurements. 2. Know the lab safety rules, and the location of all safety equipment. Be able to apply the rules to laboratory situations. 3. Know the units that are used to measure length, mass, temperature and volume in the metric system. Be able to explain the benefits of the metric system, and estimate measurements of everyday objects. Know how to read graduated cylinders, triple beam balances, thermometers and rulers, and know when each should be used. 4. Know the steps of the scientific method, in order. Be able to use the scientific method to design an experiment. 5. Know the difference between an observation and an inference. Be able to classify observations as either qualitative or quantitative. 6. Be able to determine the independent, dependant and controlled variables in an experiment. 7. Be able to calculate percent error when given the formula. Know how to apply a scale ratio to an object. 8. Be able to set up, complete, and interpret data tables and graphs. Know how to correctly set up and graph data, including titles, keys, labeling the axis, plotting points, and using a consistent scale. Be able to analyze mistakes made on a graph. Know how to interpret a scatterplot with a best-fit line. 9. Know the difference between human and experimental error. Be able to analyze sources of error within an experimental design. 10. Be able to explain and analyze the results of fingerprint, chromatography and footprint forensic tests that were conducted in class. Know the strengths and weaknesses of each test.
