Part 1—Height : Weight Ratio

  1. Fill in the following chart:

Height (in cm) / Weight (in kg) / Height ÷ Weight (Actual) / Height ÷ Weight (Expected)
4 cm/kg
  1. Answer the following questions:

Is height in centimeters equal to four times weight in kilograms? Did you support or refute the hypothesis?

Part 2—Arm Length : Height

  1. Fill in the following chart:

Height (cm) / Arm Length Expected (cm)
(Height (cm) x 0.4) / Actual Arm Length (cm) / Deviation from expected
(Actual – Expected)
  1. Answer the following questions:

Describe your procedures for taking the arm length measurement. Is there a standard for measuring arm length? Why is it important, in scientific terms, to have measurements like these standardized?
Did you support or refute the hypothesis that arm length in centimeters is .4 of his height in centimeters? Do you think any of your online classmates found the alternate result? Why or why not?

Part 3—Hand Temperature

What factors do you think might affect a person’s hand temperature?
What is your hypothesis about hand temperature?

Answer the following questions:
