 * Topic-** Sense of smell


 * Questions-** Will people be able to correctly guess the correct foods using only their sense of smell?

When you smell something your are smelling odor particles. There are millions of them floating around in the air. As you breath in, air enters through your nostrils, which filter in the little hairs, everything passes through these on their way into your body. The hairs are called cilia, which basically take all the dirt out of the hair that your breath in, before it goes to your lungs. After passing through the nasal cavity the air goes through a layer of mucous which leads to the olfactory bulb. Smells are recognized because each smell molecule fits into a nerve cell. The cells then send signals to your brain, and your brain interprets the smell. []

 * __How You smell__**

Your nose actually plays a great part in eating food. Most people just think the tongue has any matter in what you taste. Both senses go together the nose detects the odors which causes the mouth to be able to taste the food more fully. If you pinch your nose while eating you will no longer taste specific flavors. You will taste sweet, sour, and salty. []

Humans can distinguish more than 10,000 different smells. Different nasal receptors encoded by different genes recognize different smells. You may have heard the saying I smell the taste of that, which is not such a crazy thought. Your nose recognizes the texture of the food, and you brain will process and recall the type of food that you are eating. Hypothesis []


 * Hypothesis-** My question was will people be able to correctly guess the correct foods using only their sense of smell? I think that seven people will be able to correctly guess all the foods, using only their nose.

1) Before doing the experiment make sure that you have all the materials needed. 2) Select about 15 people to participate in your experiment 3) Have you foods laid out on a table, to test on your participants 4) Blind fold the people so they won't see what the foods are and it will be a complete surprise 5) Hold each food up to the people's noses until they make their guesses 6) In next to each spot where the foods are listed put a check next in the box that says yes if the guessed correctly, or in the box no if they were wrong 7) When you have finished your experiment look at how many people correctly guessed the foods and hoe many people got it wrong 8) After I add up the totals I will be able to see if my hypothesis is correct or if i was wrong.
 * Procedure-**

1) At least 15 participants 2) A blind fold 3) At least 5 different kinds of food that will be tested on people 4) Gloves so the scent of my hands won't disturb the smell of the food 5) Pen and paper to record the data

In my conclusion I stated that half the people with is about seven would correctly guess all the foods. From taking a quick glimpse at my results you can easily tell that there were a few people who came very close but only got a couple wrong. After counting the exact number of people who got them all right there was a total of two which wasn't even half of what i was expecting. After doing my research I learned that identifying foods without using your nose can be a challenge, and from my results it is more of a challenge than others. If doing the experiment a second time I would like to change the fact that the foods that I test would be more different in smell. I would like to have some foods out of the sweet section the sour and so on. From doing this experiment now I wouldn't change the fact of how many people I did, and I would keep the same amount of foods that I tested on the people!
