A violinist's fingersFeatured science projectScience project video

Abstract

This science fair project was conducted to find out if experienced violinists have longer fingers on their left hand. The science fair project involved violinists who have been playing the instrument for more than 5 years.

Hypothesis

Violinists have longer fingers on their left hand, while non-violinists will have shorter fingers on their left hand. We base our hypothesis on the fact that a violin is normally held and fingered with the left hand (the right hand is used for bowing), and the assumption that the frequent movement of a violinists fingers on the left hand, will result in accelerated growth and hence, longer fingers.

Scientific Terms

Bone, tissues, ribcage, skull, osteoblasts, osteocytes, osteoids

Background

Bones

Bones are a form of specialized tissue. They are very strong and durable. Bones in our body will elongate and grow starting from the time we are born until adolescence. The rate of development of our bones will also depend on, amongst other things, the amount of nutrition, exercise and exposure to sunlight. Sunlight helps us produce vitamin D - which is important for absorbing calcium.

Our bones provide the frame and structural support required to hold our flesh, organs and muscles together. They also provide protection for our vital organs. For example the ribcage protects the heart and lungs, while the skull protects our brains. Bone marrow found at the core of our bones, is used to produce blood cells and to store fat. Bones also act as a reservoir for calcium storage.
