Section 2.1 Scientific Methods
Objectives
1. List and describe the steps of the experimental method.
2. Describe why a good hypothesis is not simply a guess.
3. Describe the two essential parts of a good experiment.
4. Describe how scientists study subjects in which experiments are not possible.
5. Explain the importance of curiosity and imagination in science.
2.1 Vocabulary
observation - information gathered by using sight, hearing smell, and touch
hypothesis - testable explanation for an observation
prediction - logical statement about what will happen if a hypothesis is correct
experiment - procedure for testing a hypothesis under controlled conditions
variable - the factor of interest
experimental group - the group that receives the experimental treatment
control group - the group that does not receive the experimental treatment
data - information gathered during an experiment
correlation - association between two or more events used to study a subject when using an experiment is impossible or unethical

The scientific method is a set of guidelines for scientific investigation. It helps us approach all scientific experiments and inquiries methodically and scientifically in order to avoid jumping to conclusions or missing links in a logical chain. The five steps of the scientific method include 1) defining the problem 2) making observations, 3) forming a hypothesis, 4) conducting an experiment and 5) drawing conclusions.

Experimentation is the fourth step of the scientific method. Science experiments are necessary to test hypotheses and to form accurate conclusions based on real world results. All branches of science conduct experiments.
