Transcript of The Nose Knows Smell but How About Taste

Abstract
The experience of enjoying eating is really a combination of taste and smell. If you don’t believe it, than this experiment will prove you wrong. Anyway try eating a food while holding your nose shut. You will see how important smell is to food. Don’t forget there are also other senses such as the heat from spicy foods and the tingling from soda. Flavor is the word used to describe the feeling of taste and smell together, along with any other senses experienced while eating.

In this experiment you will find out how and why you can taste stuff with your nose. There will be volunteers that test it out and see if this theory is right. If your looking forward to finding out more information about taste and smell, continue reading and learning!!
Introduction
Hypothesis
If the nose knows smell then it should know taste because the nose is what has the two senses out of the five which are smell and taste.
Materials
Procedures

1. Recruit your volunteers for the taste test. Be sure to ask them if they have any food allergies so you don't include those foods in your samples. Let them know the day and time of your experiment and how long it should take.

2. Make a list and gather up the foods you want to use in your experiment. You might consider having a few extra foods in case some of them don't end up working well as samples or taste too strong or bad to include in your test.

3. Prepare your samples, taking care to make sure the texture of the original food is not too recognizable. For instance, you'll want to completely blend peanuts so your volunteers can't identify the peanuts by the crunch or feel of the nuts. Food like salsa should also be blended so that the peppers and onions are not obvious.

4. You should try tasting each sample yourself so that you'll know if any is too unappealing or strong to use in a blind test with your volunteers. Remember, you are trying to test their ability to taste and identify foods they typically eat, not gross them out.

5. You can probably prepare many of your samples the day before and keep them in the refrigerator overnight, if necessary. Keep in mind that some foods lose their flavors if cut up or blended and stored for too long, so some samples may have to be prepared the day of the test.

6. Be sure all samples are at room temperature when you have your volunteers taste them since temperature can affect flavors.


Results
Conclusion
In the beginning of this experiment I thought that humans were able to taste with their nose because when your sick your nose is clogged up with thick mucus which doesn't let the smell from your nose get to your mouth so you can have a delicious taste. During this experiment I observed that even though my hypothesis was supported by my results, there were a few errors that could of effected the results.
One error that I made were that one of my volunteers saw what I put together for her to eat. But she said that it tasted like nothing still.
Thanks for taking this journey

Think about the last time you had a cold and your nose was blocked. Do you remember eating and thinking that your food was tasting bland? That’s because most of what we taste is actually being sensed by our nose. In this experiment we will investigate the influence of smell on taste. We will find out interesting stuff that you may have not learned about. Such as how the brain receives and processes information sent from taste buds and the nose If you try this experiment you will find out these answers.
Procedures
7. The day of the taste test, explain to the volunteers that they will be trying a group of food samples with the nose plugs on and then the same set of samples with the nose plugs off. They also will wear the covered swim goggles during the test so that they won't be influenced by what the samples look like. Reassure them that they may taste some strong flavors, but you will be giving them food that they normally eat, nothing that is inedible.

8. Do the taste test with one volunteer in the room at a time so that the other volunteers do not hear any responses before it is their turn to try the food samples.

9. Assign each volunteer an identification number so that your data can be recorded anonymously.

10. For each sample, ask the volunteer to describe the type of flavor that they detect. Record their response(s) in your notebook. If they can't really identify any specific flavor, indicate that as can't identify.

11. Next, ask them to try to identify the food. Also record their response and whether they were correct, close, or incorrect.

12. Let the volunteer have a sip of water between each sample so that they cleanse their taste buds before trying the next food.

13. After each volunteer finishes each set of samples with the nose plugs on and without, you can have them remove their goggles and let them see what they have been tasting.
