Diary of the Heart Dissection

     For several weeks we have been talking about the project about the heart dissection and the tablets that the high school is going to buy.

     Weeks later, Sergio came to class and gave us the news:  the tablets were already  and able to use them. First we have some problems with the conections and the paswords but finally we can use them.

     We had to find a specialist on twitter that help us with the dissection. We find Lesli Samuel who gave us a page with a plan of a dissection.

     The next day we show it to Sergio in the tablet and he smile us... :)

    The following days we were preparing the plan that we have to show in class. We had some problems because we didn't have enough time so we did by phone.

    The presentations began on 7 of March. Aranzazu and I not present because we wanted to see some presentations before.

     We present on Friday. We were very nervous, but we did well. At the end Sergio gave us the congratulations because we did it in a program that he liked.

     Some people they haven´t present, but there are few groups.  

    I think that this week (Monday, 11 of March) or the following, will do the dissection...That´s funny!

    Finally we did the dissection the last week before the Easter holidays (thursday 21 of March). Everyone brought hearts in bags and left them at the first hour in secretariat.  

     In the hour of biology (after the breaktime) we went to the lab and sit with people from our group. Mary handed out gloves, trays, scalpels and scissors and told  that we put us our gloves,  take out the heart of the bag and put it in the tray . Then everybody started to dissect following the plan he had written. At the beginning  Carla and I didn't want to touch , but we had to do it , so we turned it and started to put pencils by the aorta, the pulmonary vein... We weren't very sure where it was every one but Ismael Cabrera helped us.

     Next , one class of Bachillerato come to saw and helped us with take pictures because our gloves are dirty. A guy took the picture while we were situated the pencils. 

    When we started to cut the heart was very hard and as much as we tried it we couldn't so Dani  helped us (For this reason the hands that appear in the video are so big). After cutting it in half, we saw the connections and valves. 

     At the end we were very dizzy by the smell and Carla wanted to not having breakfast...

     We collected everything and we threw it in the trash but before throwing the heart Dani 

asked us that we leave it to break it with his hands, I think that he had fun. 

     The photos are colocated in order:

Heart Dissection

Heart Dissection

- First Step: 
          

Remove the gloves and the scalpel of the bags or boxes. This step will do Carla.Then, we put our gloves.

- Second Step:
           

We have to remove the heart from the bag.This step will do Aránzazu.

- Third Step:
Put it on the table and indicate with colored pencils: vena cava, pulmonary vein, aorta and pulmonary artery.
  To find the aorta you have to find the pulmonary vein because the aorta should be situated a little bit behind it. Next you put the red pencil (aorta) and the blue pencil (pulmonary vein). This step will do Carla.   The two main veins can be found on the backside and come in left and right atria. Then you put the green pencil (vena cava) and the yellow pencil (pulmonary artery). This step will do Aránzazu.

- Fourth Step:

Use the superior vena cava and pulmonary vein as guides for where to cut. This step will do Carla.

- Fifth Step:
When the heart is open, you can see the inner chambers.

Aránzazu records (When we cut the heart) and Carla takes the photos of ALL.

Diary of the lungs project

Materials

    To make the lungs is necesary : 

 - Scissors

 - Two drinking straws 

 - Heat tape         

 - Packet of ballons                                                                                                         

 -Clear plastic soda bottle

 First Step:

We took the bottle and cut through the bottom.Then we had to clean it on the inside because it had a few of water. We put soap,  water and dry it.

 Second Step:

After washing the bottle, we ironed the cut side for didn't break the balloon, that  we use like a diaphragm.

 Third Step:

 After filing, we took the cap and got two straws glued with adhesive tape so

 that they cannot move. 

 Fourth Step:

We take two balloons ,we cut the top and we stick them to one end of the 

straw with the heat tape.

 Fifth Step:

We take another balloon and we cut it too, then we 

put it at the end of the bottle.

Finally we check if it worked...

Problem and Solution

 Problem:

  

    -The balloon that had to be put at the end of the bottle, as a diaphragm, was very difficult to put. The balloons were too small we broke four. ¬¬''

 Solution:

    -The solution found was take one of the small balloons and inflate it to make it easier to handle.

Breakfast

First breakfast

I intake  a sandwich of omelette with ham and cheese , a glass of hot milk , a yogurt and a banana that  Maria gave me . At the end I felt very sat , in the rest of the classes until the breaktime I was a little distracted  and in P.E.  I didn't really want to run , at breaktime I wasn't hungry. 

    Omelette with ham  ( 104 kcal) cheese (10, 5 kcal) milk ( 70 kcal) yogurt ( 126 kcal) banana ( 122kcal) Total = 432,5 kcal

Second breakfast 

I intake a sandwich of serrano ham and cheese whith a yogurt and a orange juice . This time I felt full also but the rest of the day I felt so motivated , with a lot of energy , maybe more happy . At breaktime I wasn`t hungry too.

  Sandwich with serrano ham  ( 134 kcal) cheese (10, 5 kcal)  yogurt ( 126 kcal) orange juice (84 kcal) Total = 354 ,5 kcal

Breakfast

BREAKFAST:

•      Difference between the first breakfast and the second breakfast:

            I think that the second breakfast was more healthy than the first breakfast.

•      Nutrients and calories:

           FIRST BREAKFAST                                         
   
       Milkshake: 97Kcal
       Biscuits with chocolate:481+ 518 = 999Kcal
                
                 TOTAL: 999+97=1096Kcal    

           SECOND BREAKFAST      
  
        Sandwich of  ham: 268+105+268=641Kcal
        Milk:37Kcal
        Banana:83Kcal

                  TOTAL:641+37+83=761Kcal

•     Opinion:

            My opinion is that when i finished my breakfast i felt with more energy and better than other days.

Breakfast in class

Carla 

First Breakfast

    In my first breakfast I ate a ''Cuña'' with a  Tropical juice . This breakfast was very unhealthy because I ate a lot of calories. The only healthy food that I ate was a banana ( My teacher María gave it me). At the beginning I felt very god because I love chocolate but later I felt very bad and tired. The calories that I need intake in the breakfast are 899.64 Kcal.
            
              420( The ''Cuña'') +200(The Juice)= 620Kcal

That day I took 620 Kcal and is very bad because the most nutrients that were in my breakfast were fats.   
In the next breakfast I need intake more calories but not only fats, I need diferents nutrients like fibre.

Second Breakfast

   In my second breakfast I ate an orange juice, milk with ''Cola-Cao'' and a sandwich with jam and Philadelphia cheese. This breakfast was very healthy because I ate very good. All the day I felt very good, energetic and animated. The calories that I need intake are 899.64 Kcal but that day I took...

52.2 (The Orange Juice) +115.25 (The Milk with Cola-Cao)+

286,5 (The Bread, The Jam and The Philadelphia Cheese) = 453.95Kcal.

 I don´t know  why I only intake 444,25 Kcal because I felt very sat and I couldn´t eat more. If we have brekfast in class again, I try intake all the calories that I need intake in the breakfast, I hope :))
