Project Name : Toaccurately estimate adults heart rate.
Theme Name : Mathematics Modelling
Scientific principle involved: Simple Algebra and experimental formulation
Future scope: To predict the beats per minute in less time using formula substitution. It will be very useful in identification of illness and helps in saving valuable human hours and helps India develop into a healthy and useful society.
Materials used: clay, foam, wood, colours, motors, batteries, thermocol and switch.
Concept: We have tried to formulate the beat of the heart using 2 variables i.e age and how they feel.
For the case of simplicity we have grouped the age factor as age index. It can be defined as follows.
Age Index:
10-30=1
30-50=2
50+ =3
299
About the Model: The firstmodel is made out of clay.
The second model is made out of foam. The foam is cut into heart shape. It is hollow inside. Inside the heart there is a 6v motor and two 9v batteries. A Velcro is fitte4d with the motor. When is motor is on the Velcro makes the foam to expand and contract making the heart look like it beats. A switch is present to regulate the heartbeat.
Name of the School: Jawahar Vidyalaya Sr. Sec. School, Chennai.
