how does smell affect taste THE PROBLEM

How does smell affect taste? MY HYPOTHESIS

If I blindfold people and have them use a nose plug while testing different flavors of lifesaver gummies, and then have the same people taste the same gummies without using the nose plug.

Then I expect the results to be different.

Because when you use the nose plug you can not smell the lifesaver gummies, but when you do not use the nose plug you can smell the lifesaver gummies. MATERIALS


Paper
Pencil
Lifesaver gummies
Bandana
Potato chip clip (nose plug)
Friends/family
Camera
Water
Plastic cups PROCEDURES

Step 1: Put a nose plug on your friend.
Step 2: Put the blindfold on your friend.
Step 3: Give a lifesaver gummy to your friend.
Step 4: Take a pic of your friend.
Step 5: Have your friend guess what flavor the gummy is.
Step 6: Repeat the process for 4 more tria the food in my expierement to life savor gummies. i am measuring how smell affects taste. i am measuring my expierement with a graph. i am keeping the trials the same i n my expierement variables RESEARCH

I learned that the roof of your tongue has millions of tiny taste buds.

I also learned that bitter taste is at the back of your tongue.

In addition, I learned that there are two sour parts on your tongue, one on the right side and one on the left side.

I learned that your taste buds detect temperature and texture.

I also learned that it is harder to taste food when you have a cold.

In addition, I learned that we stop tasting our food after the 3rd or 4th bite.

I learned that 73% of your sense of taste comes from your sense of smell.

I also learned that animals need their sense of smell to survive. OBSERVATIONS


Trial 1
Friend: Wes

Blindfold and nose plug Blindfold only
Flavor given Tasted Flavor given Tasted

Green Apple Corndog Green Apple Apple
Strawberry Medicine Strawberry Cherry
Cherry Sweet Cherry Cherry
Blackberry Nothing Blackberry Blackberry
Watermelon Nothing Watermelon Watermelon


My observations in this trial is that my friend Wes, was able to tell me the correct flavors while blindfolded, but could not guess the flavors while wearing the nose plug. The reason he could not guess them correctly was because he could not smell what he was eating. Trial 2
Friend: Maddy

Blindfold and nose plug Blindfold only
Flavor given Tasted Flavor given Tasted

Green Apple Fruit Juice Green Apple Green Apple
Strawberry Corndog Strawberry Green Apple
Cherry Raspberry Cherry Blackberry
Blackberry Blueberry Blackberry Cherry
Watermelon Nothing Watermelon Watermelon

My observation in this trial is that my friend Maddy was not able to taste the flavors with a nose plug. She did not get them all right when she was blindfolded and that might be because she did not drink enough water after each taste trial. Trial 3
Mom

Blindfold and nose plug Blindfold only
Flavor given Tasted Flavor given Tasted

Green Apple Sour Green Apple Green Apple
Strawberry Sweet Strawberry Strawberry
Cherry being blindfolded only. My mom could not guess the flavors of the gummies when she used the nose plug.
Cherry Cherry Cherry
Blackberry Sweet Blackberry Blackberry
Watermelon Sweet Watermelon Watermelon


My observation in this trial is that my mom was pretty good at guessing the flavors while she wasn’t so good when she had the nose plug on. Trial 4
Friend: Chad

Blindfold and nose plug Blindfold only
Flavor given Tasted Flavor given Tasted

Green Apple Sweet Green Apple Cherry
Strawberry Nothing Strawberry Green Apple
Cherry Sweet Cherry Blackberry
Blackberry Nothing Blackberry Blackberry
Watermelon Nothing Watermelon Green Apple

My observation in this trial is that Chad is not very good at tasting the flavors without the nose plug and with the nose plug. This trial showed that with the nose plug he could not actually taste a specific flavor like when he was only blindfolded. Trial 5
Friend: Rachel

Blindfold and nose plug Blindfold only
Flavor given Tasted Flavor given Tasted

Green Apple Nothing Green Apple Green Apple
Strawberry little fruity Strawberry Watermelon
Cherry Nothing Cherry Blackberry
Blackberry Nothing Blackberry Watermelon
Watermelon Fruity Watermelon Cherry

My observation in this trial with Rachel is that she was not very good at tasting the different flavors while blindfolded. I think she did not drink enough water between taste trials. When she used nose plug she was not able to taste much. CONCLUSION

My conclusion is that you need your sense of smell to taste the food that you eat. I also leaned that even when you are blindfolded sometimes you can get the flavor of a food wrong. So I think being able to see also has a lot to do with how you know what you are eating.

While doing my research I did learn that we stop tasting our food after 3 or 4 bites, we are only, smelling the food after that. Based on the trials that I did with the nose plug this is true. Most people in the trial said that they tasted nothing. My observation is that it is correct that we stop tasting our food after a few bites when we can not smell it.


I also learned that it would not be much fun to eat if we could not taste or smell our food. If we did not smell our food we would only be able to taste sweet, bitter and salty. A lot of the foods that we love to eat would not be much fun anymore.
