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

Table 1. Data CollectionSubject

Index finger length

Hand span (pinky to thumb)

Forearm (Wrist to elbow)

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?
