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


Materials required for this  science fair project:

-    10 boys and 10 girls age 15
-    10 men and 10 women age 30
-    1 computer game with 20 levels (try something fairly simple to play - for example, a shoot' em up)
-    1 computer
-    1 quiet room


1.    The independent variables in this science fair project are the gender and age of the participants. The dependent variable is the highest level reached by the participants in the computer game, which is determined by selecting the highest level after three attempts. The constants (control variables) are the type of computer game chosen, the computer used, and the number of attempts given to the participants.

2.    Select participants aged 15 years old and 30 years old, ten for each gender and age, to take part in this study. All 40 participants will be participating in this study one at a time. 

3.    Install the computer game into the computer and go through the rules of the computer game and necessary keyboard functions for 15 minutes to each participant. Alternatively, you could pick a game from popular flash game websites such as, or For our experiment, we picked Heli-Attack 2. All 40 participants will be given the same instructions.

4.    Allow each participant three attempts to reach the highest possible level that they can achieve in the game. Record the highest level out of the three attempts in the table given below.
