A lab report on whether the sense of smell affects the sense of taste.
Can You Taste Without Smell?
Question- Does the sense of smell affect the sense of taste?
Background Info- You can’t taste if you don’t have an olfactory gland( gland that lets you smell).
You can taste simple flavors like sugar and salt if you don’t have an olfactory gland.
Humans can only taste five different flavors( salty, sweet, bitter, sour, and unami), but smell thousands of different smells.
Smell consists of 75% of taste.
Your nasal passage connects to your throat.
My Hypothesis If the sense of smell is taken away, then the sense of taste would be gone.
About the Experiment
The experiment is designed to distinguish if taking away the sense of smell, will take away the sense of taste, but the tastes salty, bitter, sour, sweet, unami will be slightly distinguishable.
The materials include: about 20-30 skittles, five of each flavor.
The variables are the flavor of skittles, sense of smell, sense of taste, sense of sight, and amount of skittles.
The independent variable is the sense of smell.
We will control the variables by using the same flavors for tasting, we will use the same amount of skittles for both groups, and we will close our eyes throughout the whole experiment.
The experimental group will pinch there nose to cancel out the sense of smell, then close their eyes, they will consume one skittle and try to guess what flavor it is. Then repeat this five times in each trial.
The control group will close their eyes. Then consume one skittle. They will then try to guess what flavor it is. They will repeat this five times in every trial.
Based on our results our hypothesis was correct. If you take away the sense of smell, then the sense of taste will be taken away. In both trials our results were relatively similar. Our control group would guess most of the skittles correct, while the experimental group had a lot of trouble trying to guess the flavors. Our experimental and control results were what we predicted to be. Our results on trial one for the control were lower then trial two’s probably because we ate gum before the experiment. Some confounding variables in this lab could be chewing gum before the experiment, and accidentally breathing through our noses.
