Child birth is one of the most fundamental events in human existence. A key indicator used in the assessment of a baby after a successful birth is the baby's birth weight, as well as the baby's weight in subsequent checkups. Underweight babies have a demonstrated higher rate of mortality and are at high risk of developing a number of serious medical conditions. Identification of risk factors associated with birth weight is, therefore, an important task in post-term child healthcare provision. In this Real World Engineering Project, students are asked to design and construct a mechanical or electromechanical system to measure the weight of a baby immediately after birth and at discrete intervals representing growth over a two month period.
