1.3 Scientific Thinking and Processes
Like all science, biology is a process of inquiry or problem solving.
.
• Scientific method- an organized way of problem solvingSteps: 1 state the problem 2 gather information
3 form a hypothesis 4 test the hypothesis – set up an experiment were only
one factor you are testing will change. control group – set up that does not contain the factor you are testing experimental group – set up that does contain what you are testing Variables – factors you are testing independent variables – factors you have decided to test dependent variable – factors that you don't know the out come until the end of the experiment Constants – factors that always remain the same5 record data: quantitative data- measurements
qualitative data- describing6 analyze data7 conclusion: accept or reject the hypothesis, does my data prove or disprove the hypothesis

1.3 Scientific Thinking and Processes
• Experiments allow scientists to determine what causes a phenomenon.

1.3 Scientific Thinking and Processes
A theory explains a wide range of observations.
• Theories explain a wide range of observations and experimental results.
• A theory is supported by a wide range of scientific evidence.
• Theories can change based on new evidence.
