Still pumping that blood!

Thursday April 21 - Heart Dissection!

On Thursday we dissected a heart! But before all the cutting, we took a quiz on the heart, parts of the part, and functions those parts carry out. This dissection was on UP27-32. Before you cut the heart ''like a doughnut'' Mrs.Stein quizzed each lab group to make sure you knew the parts of the heart. Then we cut it in half, and examined in interior of the heart. Gross, right? But actually there were some neat things you could do. If you stuck one finger through the pulmonary artery and another through the superior vena cava (I think) you could touch your fingers!
The homework due on Monday were as follows:
Finish UP27-32
4 Corners worksheet on 33.2
Here are some pictures of the heart:
Monday April 25 - Pulse Lab
At the start of class, we got back some graded work and a grade report! We went over our quizzes and overall, the average was a C. Today before beginning a lab we talked about your pulse, just to get a gist of things before the lab. For the lab we worked in partners. We first tested our resting heart rate and then did several activities meant to increase of slow down your heart rate such as holding your breath or exercising.
The homework from today is as follows:
Read AND annotate UP33-35
Finish Pulse Lab - Due Thursday!

The next scribe will be...........Amanda! (sorry :)

Of course when we walked in Mrs. Stein had the "pumps your blood" song playing. :) We got an acorn stamp for our homework. Next, we took some notes about the heart to prepare ourselves for the quiz tomorrow. We are responsible for knowing the different parts and their function. Also be familar with the diagram of the heart, and the path blood takes. At the end of class Mrs.Stein was there to answer any questions while we worked on our homework. Tomorrow we will be disecting sheep hearts! Don't forget to study for the quiz! :)

---------------------------------

After Mrs. Stein's creative way of waking us up, we started off the day when you walked into class, you were supposed to pick up a new unit packet, a new calendar, and then Mrs. Stein passed out our grade reports; it had our Digestions & Excretion Test scores' on them. Next, we were to do a sort-of activity, with 1 or 2 other people, in the UP packet - page 9 - and they were questions based on what you already know about the circulatory system. After that, Mrs. Stein just went over the answers in class before the bell rang. Finally, Mrs. Stein showed us one of her other "pump it up" songs to us while we were heading onto our next class.


Here are the answers to the packet questions:

#1: earthworm (5 pairs = 10 hearts)
#2: 5 liters
#3: 50% water, 45% red blood cells, & 5% salt, hormones, minerals, proteins, etc.
#4: 27,500,000,000,000 red blood cells (made in bone marrow and carry oxygen)
#5: 200-300 million
#6: 120 days (spleen clears out old red blood cells)
#7: 7 mm
#8: Rhosus Monkey
#9: female - 1/2 lb. male - 0.7 lb (size of a fist)
#10: 30% larger, 400 grams
#11: 62,000 miles (through diffusion, capillaries (blood vessels) transport red blood cells single file
#12: 1.5 million
#13: 60-80 - 72 beats per minute
#14: 32 beats/min
#15: opening & closing of valves
#16: bright red
