Science+Experiment+1

=Scientific Method 1 = Have you ever wondered why food loses its flavor when you have a cold? It's not your taste buds fault, blame your stuffed-up nose. Seventy to seventy-five percent of what we notice as taste actually comes from our sense of smell. Taste buds allow us to notice only bitter, salty, sweet, and sour flavors. It's the odor small amount from food that give us most of our taste sensation. When you put food in your mouth, odor from that food travel through the passage between your nose and mouth to olfactory recptor cells at the top of your nasal cavity, just beneath the brain and behind the bridge of the nose. If mucus in your nasal passages becomes too thick, air and odor molecules can't reach your olfactory receptor cells. Then your brain receives no signal identifying the odor, and everything you eat tastes much the same. You can feel the texture and temperature of the food, but no messengers can tell your brain, The odor molecules remain trapped in your mouth. The pathway has been blocked off to those powerful understand of smell--the olfactory bulbs. So why can't you just smell it and identify it?
 * Topic:**
 * Question:** How well can girls and boys identify foods using only the sense of smell?
 * Background Information:**
 * Hypothesis:** If I test 3 girl and 3 boys to identify foods using only the sense of smell then out of the 6 people that I choose one of the girls would win.
 * Procedure:**
 * Pick 3girls, and 3boys to do the experiment.
 * Place the six bags on the table.
 * Make them smell each bags twice.
 * Write down what they think is in the bags.
 * Tell them how many they got right and how many they got wrong.
 * Compare the results with the others, and see who got most or all correct out of the six.
 * Then see if a boy or girl win.
 * Date the chart with the no and yes answers.
 * Materials:**
 * 3 girls,
 * 3 boys,
 * 6 small paper bags
 * apples, bananas, eraser, pencil, perfume, and celery


 * Experiment:** Do the experiment


 * Data/Results:**


 * || apples || bananas || eraser || pencil || perfume || celery ||
 * Boy || yes || yes || yes || yes || no || no ||
 * Girl || no || yes || yes || no || yes || yes ||
 * Boy || yes || yes || no || yes || yes || yes ||
 * Girl || yes || yes || no || yes || no || yes ||
 * Girl || yes || yes || no || yes || no || yes ||
 * Boy || yes || yes || yes || yes || yes || yes ||

My Hypothesis was If I test 3 girl and 3 boys to identify foods using only the sense of smell then out of the 6 people that I choose one of the girls would win, and my hypothesis was wrong. Out of the 3 girls and 3 boys a boy had all of them correct. I think that if i asked more people to take the test then my hypothesis would be right.
 * Conclusion:**
