Key Idea I The scientific method is a systematic approach used in scientific study, whether it is chemistry, biology, physics, or other sciences. Scientists uses this organized process to do research, it provides a way for scientist to compare the work of others. There are six steps in the scientific method, these steps are not used as a check list to be done in the same order each time. However, all scientist must describe there ways the most publish there results.
Key Idea II A scientific study usually begins with a simple observation. An observation is the process of collecting information, observations are made to help make decisions. Qualitative data is normally the first type of observations scientist make. Qualitative data is information that describes physical characteristics such as shape, odor, and color. Chemists often gather another type of data that measures temperature, volume, pressure, and how much a chemical is used in a reaction. Quantitative data is numerical information that states how much, how little, how big, how fast, or how tall.

A hypothesis is a educated guess of what scientist think the outcome of the experiment will be. Without data to support a hypothesis it has no value. In order to test a hypothesis you must have several different controlled observations called experiments to conduct a true scientific method. In order for scientist hypothesis to have value there must be more than one experiment in order to change and test one variable at a time. The variable that is planned to change is an independent variable and a variable that is planned to stay the same is a dependent
