An Investigation to Find the Reaction of a Human Hand Catching an Object

Extracts from this document...

Introduction

An Investigation to Find the Reaction of a Human Hand Catching an Object What I am going to find out: An experiment will be carried out to find the reaction of a human hand. This will be done by observing the human carefully. Results from the human will be recorded by letting him catch a ruler which has been realised from a group member. The performance of the left hand will be recorded and then the right hand will also be recorded. After obtaining the results, a consideration will be made of the results which will show us an outline of the rate of reaction by the human hand. Hypothesis My prediction is the results of the experiment will be as the following. The human which will be reacting towards the ruler will react faster with the hand he is more active with. That means if the human is right handed, his reaction will be quicker then the left hand. ...read more.

Middle

We will measure the results obtained from the experiment by centimetres. The ruler is one metre long with centimetre measuring and also millimetres. We will take five results between the two hands with five members of a group. This will equal to 50 results. The members have been chosen randomly between right-handed and left-handed members. * We will start the experiment by gathering the apparatus. * We will commence by allowing one member at a time to carry out the experiment on another person. * One member of the group will hold the ruler high. * The bottom of the ruler will be lined together with the hand of the person who will have the experiment carried out on him. * The person holding the ruler high will let go of the ruler. * The person who is having the experiment carried out on him will respond to the movement of the ruler by catching it. * The point on the ruler which is caught by his hand will be recorded. ...read more.

Conclusion

You can establish this by observing the results table and looking at the averages been worked out from the results which were obtained from the members and after finishing the experiment there was an overall average worked out and this shows the right hand had a higher result then the left hand. These results were shown because when the group was put together we had more right handed people then left handed people so this equalled out as right hand having a higher average. This experiment can be changed to give better results. This can be done by having the same amount of people who are active with the right hand and having the same amount of people who are active with left hand and at same time when the experiment is been done you could have stopwatch to time the experiment. To extend this experiment and to find out how the body reaction time is you could try tasks with other parts of the body example the foot how it react to a object been thrown at it and etc. ...read more.
