Examining the effect of age on hand-eye coordinationFeatured science projectScience project video


Do adults have better hand-eye coordination than teenagers? If so, a basketball player should get better as he ages! The objective of this science fair project is to determine the effect of age on hand-eye coordination. The experiment will involve participants 15 and 30 year of age, and their hand-eye coordination will be tested using computer games.


Teenagers will have better hand-eye coordination than adults.

Hand-eye coordination

Hand-eye coordination refers to the coordination between our eyes and our hands when accomplishing a particular task. We use it everyday to perform simple jobs such as making a cup of tea, writing, playing games or driving to work. Hand-eye coordination is also involved when we catch a ball thrown towards us or pick up a book from the table.

Coordination is achieved by first using our eyes to gather information necessary to accomplish a particular task, after which the brain will process and analyze the gathered information before sending signals via our nervous system to the muscles located in our hands. Our hand muscles will then either contract or expand depending on the stimuli, and this results in the hand and finger movements that are necessary to accomplish the desired task.

Hand-eye coordination is essential for our survival. Without it, we would not be able to avert dangers such as avoiding a falling object, or to perform tasks such as building homes, hunting for food, harvesting crops and acquiring new skills while working.
