The hypothesis is that older children will have better hand-eye coordination than younger children.

You will have 5 boys and 5 girls aged 10 and 5 boys and 5 girls aged 15. You will give each participant a ping pong ball and time how many times they can catch it in one minute.

You will need a ping pong ball, a stop watch, a flat floor surface, and an assistant to time the experiment.

The results showed that the 15 year old children had better hand-eye coordination than the 10 year old children. The 15 year olds were able to catch the ping pong ball an average of 54-56 times compared to the 10 year olds who managed to catch the ball only 34-38 times.

This science project is interesting because it shows how age affects hand-eye coordination, which is an important skill for everyday activities.

Experiment variations to consider include bouncing the basketball off a wall and catching it, or counting the number of times the children fail to catch the ball.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
