How hand-Eye coordination is influenced by age
The hypothesis that older children will have better hand-eye coordination skills then the younger children is proven to be true. Children will normally improve in their hand eye coordination skills as they grow older.
Hand-eye coordination is very important for our survival in this world. Without it, we will not be able to perform our most basic daily chores. Most of one's childhood is spent developing hand-eye coordination skills that will help us become more independent as we grow older.
The experiment can be repeated by bouncing the basket ball off a wall and catching it. See if using the bigger basket ball produces the same results.
Try to change the experiment to count the number of times the children fail to catch the ball. You might also consider having the children play a simple computer game that involves movement or control of a joystick/gamepad.
