Great Day for a Broken Heart Challenge!!!!

The afternoon was so gloomy and dull, just as you feel when you have a broken heart... I was thinking of my favorite songs for these moments when you feel discouraged and I remembered one of my fav chick flicks(= pelis pochocleras)
Bridget Jones' diary and its opening song: ALL BY MYSELF.



Some years later the song was included in GLEE!!!



So, the challenge is this: CAN YOU ACTUALLY DIE FROM A BROKEN HEART???? A 10 for the first person who can answer this with his/her words, without copying and pasting!!!!

In case you want to hear the whole version of the song included in the episode 17 of season 2 of GLEE by the unique voice of Charice Pempengco, here you go


Looking forward to your answers!!

Heart Dissection is On!!!

Hi people!!!!! How are you doing??
 Let me remind you of the NEW groups for the practical work. It's girls versus boys this time!

GROUP 1: Gerbaudo- Fernandez Jorba- Fagoaga- Yusim- Castiglioni

GROUP 2: Lanfranchi- Lamanna- Espíndola-Burone- Vargas

GROUP 3: Williams- Amagliani- Ghio- Obiglio- Debortoli- De Aguirre

GROUP 4: Alegre- Girado- Sarcos- Uezen Bozzi- Crotto- Tshubarov- Montivero
 
Next Monday (May 25) we are dissecting the heart!!!!
So, first of all, let me clarify some rules for the lab:


Safety Rules in the Laboratory

1.   During experiments, listen carefully to instructions and follow them as exactly as you can. In case of confusion or uncertainty, ask questions! Performing unauthorized experiments will not be tolerated.
2.   No horseplay will be tolerated.
3.   Never eat in lab or drink out of glassware. Never taste or smell anything unless you are given specific directions to do so.
4.   Any injury, major or minor (cut, burn, etc.), must be reported to the teacher at once. Put cold water on burns first. Chemical spills should be washed off immediately with water. Know the location of all laboratory safety equipment. Chemicals in the eyes must be flushed immediately with the eyewash. Hold the eye open, rotate the eyeball, and continue washing for 10-15 minutes.
5.   Do not touch equipment without permission. All unauthorized experimentation is strictly forbidden. This includes all chemicals, models, or apparatus. Complete all pre-lab work. Don’t do any lab procedures until approved by instructor.
6.   When heating a test tube, always point the open end away from you and others. It should be at a slant rather than straight up in most cases.
7.   If glass is broken, the teacher should be informed immediately. Students should not handle broken glass; teachers will dispose of broken glass.
8.   Dispose of all materials as per instruction. Do not assume that all liquids go down the sink!
9.   Dissection equipment can only be used on specimens. Any misuse of dissection tools will result in disciplinary action.
10.  Before class will be dismissed, all equipment and sinks must be clean, and desktops must be clean and dry.

If the above guidelines are not followed, you may not be allowed to participate in the lab and may not receive credit for the activity.


 Here you have a video on how to keep it safe in the lab:





I'm including the video on dissection for Group number 4 responsible for teaching us how to open a heart (ALL THE MEMBERS OF THE GROUP SHOULD KNOW EVERYTHING TO ANSWER QUESTIONS)

VIDEO 1



VIDEO 2



VIDEO 3



We will need some material for our experience

* HEART  (cow, pig or sheep) PLEASE, ENCARGUEN EL CORAZON AL CARNICERO CON ANTICIPACION PORQUE NO ES UN PRODUCTO QUE TENGAN TODO EL TIEMPO
You must bring it to school in a lunch box


LATEX GLOVES ( Each group can buy a box of gloves to have them for later experiments)
* SCALPEL - Two per group  (you can buy them at the drustores near the Faculty of Medicine.- Farmacia Rex, for example)
* WIPING TOWEL to clean the table after the experiment

* KNOWLEDGE about circulatory system

* YOUR OWN HEART filled with energy for a new experience

See you on Thursday!!

Visiting Mickey Can Be Really Contagious!!


Well, this was at least the situation back in January 2015!!!

Measles was confirmed in 59 California residents. Additionally, there were a handful of related cases in Utah, Washington, Colorado, Oregon, and Mexico—bringing the 2015 total to 67, according to the California Department of Public Health.
The patients in California ranged in age between seven months and 70 years, and at least 28 of them were unvaccinated. But that wasn’t all by choice: Six are infants who were too young to receive the shot. The first dose of the MMR (measles, mumps, rubella) vaccine is typically given to children 12 months or older, with the second dose administered before they start kindergarten around age five.
Of the confirmed cases, 42 were linked to Disneyland or Disney California Adventure Park in Orange County.
Measles is a highly contagious viral disease that spreads rapidly through the air from coughing and sneezing. The initial exposures occurred in December, but additional confirmed cases visited the parks while they were infectious in January. Less than two weeks ago, only nine cases were confirmed in this California-centered outbreak.
Because there are also cases where the patients haven’t visited Disneyland—or any venues where travelers congregate, such as other amusement parks and airports—the health department recommends that measles be considered in any patient with clinically compatible symptoms at this time. It usually starts with a fever that lasts a couple of days, followed by coughing, runny nose, pink eye, and a rash that appears on the face, hairline, behind the ears, and eventually the entire body.
The U.S. experienced a record number of measles cases in 2014, with 644 cases in 27 states, according to the Centers for Disease Control and Prevention. That’s the greatest number of cases since measles elimination was documented in the country in 2000.




This is the link to a great article on the same topic in one of my fav. science pages

Even Diego Golombek talked about this topic in his La Nacion column:

Quite a topic,isn't it? Let's discuss this tomorrow!!!

Let's Start Reviewing For Your Test

Hi, people!!! Ideal rainy afternoon for a post! After our class on Thursday, I´ve been surfing the net to find some videos that can help you understand the relationship between surface area and volume. This is a key concept to understand absorption in every part of our bodies.
So, less talking and more doing!!! In the first video, a Biology teacher explains why cells are so small



We saw this video in class about the implications of the surface area to volume ratio (=proporción) in cells



This is an interesting video to review the mecanisms of transport of substances IN and OUT the cells




To review ENZYMES


If you need material to review DIGESTIVE SYSTEM, there you go!


and last year's powerpoint on units 10&11



Ta,ta!!
Ms ANDREA

PS: So far there are no winners for challenge 1 and only one winner on INSTAGRAM for challenge 2, so DON'T GIVE UP!!!
