Whooo, April fools day!

What We Did Today;

1. Discussed S.T.S. (Space Tourism Society? NO, it stands for Science and Technology Studies.... right?) and the variations in digestive systems, as well as "bad foods".
2. "Ham Sammy" -- Started the assignment that consisted of writing a story of a ham sandwich going through the digestive system. (Due Thursday!)
3. Went over the "thought lab" from Monday

Thoughts and Opinions;

1. Wow, there is a lot of obesity in our society! Maybe there should be less pop machines and more water/juice drink machines?
2. I never knew you could basically get a dog to salivate by ringing a bell.. wonder if humans can be taught to do that? :P
3. How does a person get Celiac disease, and what are the symptoms?

Above and Beyond;

• A person gets Celiac disease genetically (if your parents had it, you have a chance of having it yourself), but it doesn't present itself right away. Sometimes a person won't know they have it until they're an adult, and some might be diagnosed with it when they're a toddler. Celiac disease often shows itself after a stressful event such as surgery, childbirth, infection, or illness.
• Some symptoms of Celiac disease are weight loss, fatigue, abdominal bloating, diarrhea, and anemia. If someone has these symptoms and go see their doctor, they will go through blood tests, or possibly even a bowel biopsy.

April Fool's Joke; "Classically Conditioning Craig to Salivate"

After hearing about Ivan Pavlov, a biologist/scientist who was able to classically condition dogs to salivate when they would hear a bell ring, Jen & Craig volunteered to go through an "experiment" to see if humans could start to salivate when hearing someone talking about food, and what Mr. C told them to do was:
Jen was to listen closely to Craig's stomach while Craig listened to Mr. C talk about Belgian waffles. Jen was listening for Craig's stomach to 'secrete gastric juices', but all she could hear was Craig laughing and Mr. C talking. We found out later that it was a joke. APRIL FOOLS!
