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)

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)

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

Conclusions
1. What is the ratio of your height to your arms span? 2. Is your arm span the same as your height? How
about your group members?3. What is the ratio of your height to your forearm?4. What is the ratio of your hand span to your index
finger?5. If the ratio is 1:1 what does it mean?6. Compare yourself with your partners, does everyone
have the same ratio? Who does and who doesn’t?7. Does your data support your hypothesis?
