Investigating into reflexes & senses

> The experiment is done in the same place always

> The ruler is always dropped at the same height

> The ruler is dropped at the same speed

Method: - First we would get our apparatus and set up our experiment. Then, one person would drop the ruler through one of the hands of the other persona and record how high the person's hand was on the ruler. The lower measurement, the quicker the reflexes. We would repeat this with sight, sound and touch. When we were doing sound, the person catching the ruler would face a different direction while the person holding the ruler would make a sound when he/she was about to drop it. This was similar to the touch sense because the person catching the ruler would face a different direction while the person dropping it would touch it lightly on the others fingers.

Conclusion: - This table clearly shows that the results for sight were the best, the sound then touch. This may be because we are more used to using our eyes in the environment that we are in and as soon as we are born.
