Chewing Lab



Hypothesis:
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:
  1. Lab Pro
  2. Electro -Tabs
  3. Food Types
    1. Sour Skittles
    2. Baklava
    3. Chocolate
    4. 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.

Directional Terms



When I went through my Anatomy and Physiology book I learned all the different ways the body could be put into while in the anatomical position. I put all the directional terms and photos, as well as the information about each term in the slideshow above. Enjoy! :)

Organizational Structure of the Body



Awhile back I did a packet on The Human Body: An Orientation. I had to:

  1. Successfully put the levels of structural organization in order
  2. Identify and color each body system
  3. Learn vocabulary
  4. Understand how Homestasis works
  5. Correctly labels all body areas of body sections
  6. Label and color each body cavity
When I was finished with the packet I threw all that I learn, minus all the vocabulary, in a Prezi presentation which I put below. By doing this it taught me a lot about the body and how many structures and sections the body really has that either helps it operate, or just keep it together. The packet was very helpful to my learning experience to the body, and I hope my Prezi presentation will help you as well. :)
