Document Summary

Learning objectives chapter 1: read the following sections carefully: A: goal or question, quant/quali data, hypothesis, experiments, results agree with hypothesis, law, theories modified by experimentation. Or results that disagree with hypothesis, so revise hypothesis, and continue experiments. An iterative process since you continue to repeat experiments and obtain more data to get closer to the desired results. Scientific knowledge is always changing based on new experiments; no single scientific method. A: quantitative results expressed as a number with units. Qualitative results are general descriptive characteristics of material under study (color). A: number and unit: you should know the metric base units (and their symbols) for volume, mass, length, and temperature. A: volume in liters (l), mass in grams (g), length in meters (m), and temp. in kelvin (k: you need to memorize the metric equalities. Be aware that these equalities can be used with any base unit.
