Solving Problems Developing Theories Notes
2
Objective

• Apply scientific methods to problem solving.

3
Vocabulary

• Scientific Method
• Hypothesis
• Experiment
• Control
• Variable
• Theory

4
Scientific Method

• Procedure used to solve problems and answer
  questions that can include stating the problem,
  forming a hypothesis, testing the hypothesis with
  an experiment, analyzing data, and drawing
  conclusions.

5

• Observations can be made in many different
  settings.

Fieldwork
Laboratory investigation
Computer models
6
Hypothesis

• Prediction that can be tested.

7
Experiment

• Using controlled conditions to test a hypothesis.

8
Control

• Standard to which the outcome of a test is
  compared.

9
Variable

• Something in an experiment that can change.

10
Theory

• Explanation of things or events based on
  scientific knowledge that is the result of many
  observations and experiments.

11

• If data collected from several experiments over a
  period of time all support the hypothesis, it
  finally can be called a theory.
