*** OUR BEGINING IS IN THE PREVIOUS POST http://mrstsclassroom.blogspot.ca/2013/11/the-main-muscle.html
PROCEDURE For our experiment we went into Mr. Hazelwoods lab. When we got there, we saw fullgrown bulls heart sitting in a pan, a scalple, cool frog aprons, and plastic gloves. We also had a pair of scissors, but we never used them. We were told the rules of the lab and what we were supposed to do to the heart. After we found out which way the heart was facing, Kurtis started recording. Paul labeled the exterior parts of the heart. After he was finished, Steven started to cut the heart (carefully) in half with the scalple. Once steven cut open the heart, Mrs. Thompson told us that the chambers were cleaned out. It turns out there was a very andry women in Rorkton, Manitoba that got the hearts with all the veins and openings where al the valves were. She was supposed to serve them to people too (I would NEVER eat a heart!!). After that wierd story We poked around inside a little bit. It was pretty cold and slimey. When we were done ME labled the internal parts of the heart. Then DEZ labeled the blood flow with some yarn. Than we plated with it a little more. Our next step was to cut of all of the fat and predict how much fat to muscle there was in total. We were told to turn it into a percent, a fraction and a decimal. When we finished we took the heart to Mrs. Thompson, off our gloves and aprons, washed out the pans and utensils, washed down the tables, and washed our hands.
DATA Over all we think we did pretty good (eventhough ME was very discusted). We predicted the heart was about 30% fat, and 70% muscle. (30% = 3/10 = 0.3) We all agree the heart is very complex and intricate.
CONCLUSION In conclusion we found out that the heart is very interesting. It is a a very powerful muscle. We think our experiment wnt pretty smoothly. Nobody threwup (although ME was close), nobody got hurt, and it was pretty fun. We learned alot about how the heart works, and how a real heart looks like! We found this experiment alot more helpful than writing a bunch of notes for helping us understand the matters of the heart. Overall it was a pretty terrific day.
