a. Our purpose is to see if the number of taste buds that a person has influences their sense of taste. Many factors are taken into account in this process. Our hypothesis is that the more taste buds a person has the better sense of taste they will have. By better sense of taste we mean that they can more easily detect saltiness, sweetness, bitterness, and sourness. There are many factors that can also influence taste such as, smoking, tongue piercings, age, and other various health records. We believe that the four different areas of the tongue contribute to different tastes that we taste. The other four senses help to determine the tastes of things.
b. We plan to accomplish enough background research and experimentation that will prove our hypothesis. We want to show that the more taste buds you have the better sense of taste you will have. We plan to experiment by counting the number of taste buds on each person’s tongue and relating it to the way that they taste different foods.
c. The relevance of this information is to see how various health issues affect one’s sense of taste. This research is also interesting because different people taste foods differently. Certain individuals enjoy certain foods that others do not. We would like to show why this difference is so evident. These factors are also helpful in the marketing of certain foods. The way a food tastes must be pleasing to the majority of people.

This article discusses why taste buds are where they are. This arrangement many affect the different tastes individuals taste. This writing directs us to other sources of valuable information.
Embryonic Taste Buds Develop In The Absence Of Innervation
This article is a more medical approach to the topic of taste. It gives documentation of certain incidences and experiments. Cells are also discussed in this reading.
b. Our research relates to the real world in the aspect of the marketing of foods. If people have different taste senses then they will taste foods differently. This is a factor that food companies must take into account. The various saltiness, sweetness, bitterness, and sourness that are taken into account in each taste of food must be carefully monitored to peoples liking.
3. Materials and Methods
a. Our experimental design is to determine how many taste buds an individual has by conducting an experiment to count the number of taste buds on one’s tongue. These figures will help us to determine how a person’s sense of taste if influenced by the amount of taste buds. We also want to determine each person’s tongue sensitivity by testing it with different salts, foods, and waters.
b. Some important materials that will be used in the experiment of counting taste buds include: wax paper, hole punch, cotton swab, blue food coloring, and magnifying glass. We plan to place a 1” square of wax paper with a hole punch hole through it on each individual’s tongue. Next, we will swab some blue food coloring on the open hole revealing a part of the tongue. Finally, using the magnifying glass we will count the number of papillae in the view. The number of the papillae is multiplied by 250 to find the number of taste buds in each person’s mouth. To determine an individual’s taste sensitivity we will use a salt substitute and saccharin, if both of these have a certain taste it will determine one’s taste for bitterness.
c. We plan on involving the class in our study by having them take various taste tests. We are going to ask them to participate in various surveys and questionnaires. We would also like the class to measure the amount of taste buds on their tongues.
