Lipid Test
Firstly we got the 5 food items that we would be testing on
These included, Cheese, bread, dried apricot, cracker and apple, from left to right. These were rubbed in oil and left for a period of time. After removing the food from the oil we found out that the Cheese was the only food item that tested positive. The ones that remained unchanged were negative for the test







Starch Test
For the Starch test we chose the same 5 food items. The items we needed were the plate with the depressions on them with the food placed in them. After we placed the food in them, we then placed Iodine solution of 2 drops each on the food and waited 2-3 minutes to see which food items would turn black.  As you can see from the photo the food that tested positive were the ones that turned black which are the cracker and the bread. The ones that were negative were the ones that remained unchanged.










Sugar test
For the sugar test we again used the same food samples. The equipment needed for the test was 5 test tubes, test tube rack, beaker, heater, Benedict solution. We first put the food items into labelled test tubes. From left to right it was, Apple, cheese, apricot, bread and the cracker. We put distilled water into each of the 5 test tubes and then proceeded to put 10 drops of Benedict solution in them. After we put the drops in, we then put the test tubes in the boiling water for about 5-10 minutes for speed up in reaction time. Once we had taken them out we found out the the cheese, apricot and bread all tested positive for sugar as their color changed into an orange color. The ones that tested negative remained a light blue.

Colon Cancer

Watching the colon cancer surgery was not easy to look at but it indeed was pretty interesting. It was much easier to just simply look at the photos rather than watch the video.
Initially what I was surprised to see was that the patient allowed himself to be filmed and which is scary because anything could have gone wrong. The most amazing part of the surgery was the fact that little cameras were placed into the delicate area of surgery which allowed the doctors to see and for us as well! The most interesting thing to me is how the stitches were put on the body part, this seems like it would be so delicate and the fact that you can puncture it is crazy. 

Broken Collar bone

• Rests between the upper rib cage and the scapula (shoulder blade) and is an important bone, as it attaches the arm to the body
• Car accidents also frequently lead to clavicle fractures, as a result of impact with either the seat belt, steering wheel or from bracing against the dashboard with extended arms.

INTERESTING FACT

• Babies can even suffer clavicle fractures during passage through the birth canal, but fortunately the bones of children and infants heal extremely quickly.
• No surgery is needed if it's a non-displaced fracture and both sides of the clavicle are still lined up properly; an arm sling usually suffices. 

Presentation on Hookah smoke

Many people today talk about the affects of cigarette smoke on the smokers lungs and how your lungs will become damaged and how it can lead to cancer sand all those things. However, what about the hookahs? They are just as, if not more toxic in our respiratory system in about every way. They have the same toxins, shisha has more nicotine and it is becoming more common amongst high schools.

 What is hookah though? Hookah is a water pipe with flavored tobacco than can range from strawberry to grape. It creates smoke in large amounts and is one of the reasons teenagers think it is cool.

What are the risks? Hookah is associated with lung cancer, respiratory illness, low birth weight and periodontal disease. Smokers inhale higher amounts of toxins than in cigarettes. In a 1 hour long session, it involves around 200 puffs where the average for cigarette is 20 puffs.

My personal reflection with hookahs was that I lived in an Arab Country, Qatar and the city of Dubai where doing shisha was common. Everyone was doing it wherever they pleased and nobody says anything. I personally did it every weekend with my friends and it was not until this project i realized the risks.

 Observations: The test tube with the lime water with O2 being pressed into it was kept the same where as the test tube with the lime water where we were blowing into with a straw turned cloudy after a period of time.
Once we put distilled water into the 25ml in beaker, we did the same thing with the pipette and straw and then used the PH indicator. The one with the straw turned yellow and the one that was airrated was green
