1. Physical Science
Day 3

2. Chapter 1 Introduction to Science
Section 2
The Way Science Works
p. 12

3. Know the steps to the scientific method
Objectives
Know the steps to the scientific method
Discern the importance of technology
Analyze the procedures of experimental design

4. I. Science Skills
A. Critical thinking- making
observations and using logic to arrive
at conclusions
B. Scientific Method- series of steps
followed to solve problems (not rigid
rules, but a guideline)
1. Identify a problem(ask a
question!)
2. Hypothesis- if/then format (If IV,
then DV)
3. Experiment (See point C)

5. 4. Collect Data (both quantitative and qualitative) Draw Conclusions
5. Theory (can be more formal, repeated experiments can lead to this)
6. RETEST- only a valid experiment if results can be repeated

8. Chapter 1 Introduction to Science
Section 2
The Way Science Works
p. 12

9. C. Testing Hypotheses/Experimental Design
1. Control Group-do nothing for comparison
2. Controlled experiment- one in which only one variable can be changed at a time
a. Variable- part of an experiment that
can be changed
b. Constant- a variable that is not
changed in an experiment
3. Independent Variable (IV)- factor that
you change in the experiment
4. Dependent Variable (DV)- the change
that occurs because of the IV

10. 5. Confounding Factor- variable that changed the experiment that you did not intend
6. Document results and procedures
