Document Summary
Flexible: inquiry leads to observations + measurements. Observations + measurements lead to systematic patterns. Inductive discovery: when a scientist gathers observations then create conclusions, lots of observations generalizations. Scientific process/method: step 1: observations/problems/patterns we see, step 2: gather background information, step 3: develop hypothesis a proposed tentative (not stable) explanation. Heavily reliant on step 1 (observations) an educated guess: step 4: deductive reasoning. Language of science: scientific theory vs. law, theory. Hypothesis is not a theory (vice versa) Hypothesis with significant support from testing: law. A statement of what always occurs under certain circumstances. Science is used to explain why this law happens. Electron: electron = negative charge around atomic nucleus, has potential energy energy passed by motion. Energy can be used to do work: location of electron found in designated electron shells that are separated from nucleus. There are different energy levels within different shells.
