  1. How Do You Taste??????

  2. Problem Does the number of taste buds you have make a difference in if you can distinguish vinegar, salt, sugar, sour

  3. Introduction I chose this project because I have been curious about the human tongue and especially the taste buds, and why different people like different stuff

  4. Hypothesis I predict that the more taste buds you have the better you distinguish them or tell them apart because the more you have overall the more you have in each section.

  5. Variables Independent Variable: The Number of Taste Buds Dependent Variable: Whether or not it matters Controlled Variable: Everything is constant and tested the same

  6. Materials Salt Sugar Lemon Heads Vinegar Food Coloring Cotton Swabs Strips of Note Cards Every 8th Grader

  7. Procedure 1. Gather all Materials 2. Get the Vinegar, Salt, Sugar, and Lemon Heads 3. Gather up the people 4. Test Number of taste buds to see how many they have How to test how many taste buds: 1.Using a cotton swab put some food coloring on to the tip of your tongue 2.Place a reinforcement ring on your tongue 3.Count the pink dots within the reinforcement ring. This may be easier with a magnifying glass The pink dots are your fungiform papillae. They don't take up the food coloring. These papillae are the tiny bumps on your tongue that house your taste buds. The more papillae you have, the more taste buds you have and the more sensitive to taste you are. On average, non-tasters have fewer than 15 papillae in that area, while super tasters have over 30. 6. Repeat this process for the other people 7. Video tape this process 8. Observe the results 9. Test for the Vinegar, Salt, Sugar, and Lemon Heads 10. Observe Results 11. Judge Hypothesis

  8. Results

  9. Conclusion My Hypothesis was incorrect except for on a few people on all but three people because those three didn’t do a very good job guessing on the Vinegar and the Lemon Heads because sweet and salty are the first two things you taste.
