Our hypothesis was that when Sarah and Maria ate sour skittles, we would see a noticeable difference in their mV per second. We also predicted that when they ate chocolate, boklava, and gum their amount of mV per seconds would be very similar. We thought these things because Maria usually eats more sour things, while Sarah prefers sweets. We knew the sweet items wouldn’t cause a great change in mV per second because sweets don’t cause the jaw to clench up as sour or bitter tastes would. Because Maria is used to eating sour food and Sarah is not, we predicted that Sarah’s mV per second jump compared to Maria’s.
Materials:
- Lab Pro
- Electro -Tabs
- Food Types
- Sour Skittles
- Baklava
- Chocolate
- Gum
Experiment:
First we placed the electro tabs on the upper and lower portion jaw and arm. Then we recorded the mV the resting period for five seconds, then the clenching period for five seconds, for a total of 30 seconds. After recording this we, we add food to the process. First we recorded a ten second resting period, then had Sarah and Maria put skittles in their mouth then chewed for 20 seconds. We repeated these steps with chocolate, baklava and gum. We then recorded our data and graphed it.
Results:
The results we found after doing out experiment showed when Sarah ate sour skittles, her m/v per second was really high. Yet, when Maria had ate the same skittles, her jaw was normal. We decided that this was due to Maria being so used to eating sour food, where Sarah was not. After Sarah and Maria ate the sweets, we noticed Sarah’s mV per second was a bit lower than Maria’s. We also found that with our last material, gum, Sarah’s and Maria’s mV were very alike, and continual pattern.This was because Sarah and Maria chewed there gum at a consistent pace.
