13. Chapter 1 Steps of the Scientific Method
Identify the problem
Form a hypothesis
Test hypothesis by performing experiments
Analyze data
Draw conclusions

14. The Experiment
Independent variable: the item being tested in the experiment (What YOU change)
Dependent variable: the item being measured in an experiment (DEPENDS on the independent variable)
Control group: The part of the experiment that is left unchanged. (The normal group)

15. After the experiment…. Law: something that has been proven to be true
-Gravity
-Motion
Theory: something that is likely to be true, but has not been proven

17. Scientific Method Investigation
Are there specific ratios that exist between the lengths of certain parts of the body and other parts?
Create a hypothesis (a statement that answer the question above and can be tested)
Make a hypothesis

18. Hypothesis The length of your arm span is the same as your height
Example 1:1
160cm/160cm = 1:1

19. Table 1. Data Collection Subject Index finger length
Hand span (pinky to thumb)
Forearm (Wrist to elbow)
Arm length (shoulder to fingers
Arms span
Height
Foot length
Self
Partner #1 name
Partner #2 name
Partner #3 name

20. Table 2. Data Analysis Subject Ratio height to forearm
Ratio height to arms span
Ratio hand span to index finger
Ratio arm length to index finger
Ratio arms span to forearm
Ratio of your hypothesis
Self
Partner
# 1 name
# 2 name
# 3 name

21. Conclusions What is the ratio of your height to your arms span?
Is your arm span the same as your height? How about your group members?
What is the ratio of your height to your forearm?
What is the ratio of your hand span to your index finger?
If the ratio is 1:1 what does it mean?
Compare yourself with your partners, does everyone have the same ratio? Who does and who doesn’t?
Does your data support your hypothesis?
