Sensitivity essays

Sensitivity essays Each body part has different levels of sensitivity. Some places can sense things much better then other parts can. For instance your fingers would probably be more sensitive then the back of your elbow. This is because there are more nerves in one given area then another and therefore the area is more likely to differentiate between how many points that spot has been touched with. But whats the limit of which the part can tell the difference? 2 inches? 1 inch? This lab helps us all understand at what point our body parts cannot differentiate between one or two points of a compass. My hypothesis is that your fingers will be much more sensitive to the compass points then other parts like your arm. The very first thing you will need to do is gather the materials. Youll need a compass, a ruler, and something to draw a graph with. Youll have to pick out at least 3 or 4 different body parts of a group from a group of people. There will first have to be a test trail on each body part to find the measurement of about 50% accuracy. Take note of the measurement and make other measurements based on that number. Then select the parts of your body you will be experimenting with. In this case it was your fingertips, your fore arm, and your upper arm. Now take the compass and set the width of the two compass points to the largest measurement. Randomly pick how many points will touch the person who will be tested and record it onto the chart. Its recommended that you go through the procedure around 75 times. Once you have figured out when you will touch the person with one or two points, go through the process of gently touching the body part with the compass with the number of points t hat the chart says. The person will say whether he/she feels one or two points. Record that onto the chart, change the compass angle to another measurement, and repeat the procedure on the next body part. Once you have tested all the body pa...
