    Title: Calculating BMI

    Aim: To calculate Body Mass Index and determine BMI range

    Materials: BMI data, calculator, pencil, graph paper

    Methods:

    1. Use the equation provided to calculate BMI for the persons listed below [the first one has been done for you] ENSURE YOU SHOW ALL NECESSARY WORKING!

    ∙ Note that height needs to be converted into inches. and needs to be squared

    2. Organize your data neatly in a table, then use that data to construct a BAR GRAPH comparing the BMI of the 5 individuals

    Results:

    1) Rose is 5 feet 2 inches tall and weighs 115 pounds.

    · 5’2” = (5X12) + 2 = 62 inches

    · 62 x 62 = 3,844

    · 115 x 703 = 80,845

    · 80,845 / 3,844 = 21

    Rose’s BMI = 21 and falls in the 18.5 – 24.9 range, so Rose’s BMI is Normal.

    2) Tony is 5 feet 4 inches tall and weighs 150 pounds.

    3) Marie is 5 feet 6 inches tall and weighs 182 pounds.

    4) Max is 5 feet 9 inches tall and weighs 210 pounds.

    5) Amy is 5 feet 9 inches tall and weighs 120 pounds.
