In this work, a practical activity of the Body Mass Index (BMI) is carried out, using the
equations of Quételet, Melão Jr. and Trefethen as an object of knowledge of the
thematic unit “Life and Evolution” of the NCCB (National Common Curricular Base)
for students in schools in the metropolitan region of Belém and in other environments
(UFPA and squares). Initially, 10 volunteer students participated in this activity, 5 of
whom were female (F) and 5 were male (M), with an average age of 17 years and 16
years; weight 55.055.15 kg and 67.3519.95 kg; 1.590.09 m and 1.650.15 m,
respectively. In the end, they learn to use the anthropometric method and as 3 equations
of the BMI, the media that were used for F and M. Thus, it is possible to make a
preliminary monitoring of the students' health from the measurement of mass, weight
and weight. BMI. Subsequently, we increased a sample in another school, UFPA and
square and obtained satisfactory results for these measures. Finally, we tested the
Biophysics - BMI application to perform these calculations and obtain the fastest values
for BMI measurements that were used by hand or via calculator.
