El dia 30 de novembre els alumnes de 1rB vam fer una sortida per Guissona per veure algunes
roques de les façanes. Ens van acompanyar la Montse Rodríguez i la Núria Penella.
Abans de començar ens van fer un recordatori dels tres tipus de roques que havíem estudiat.
Vam veure roques de teulades, de terres, la de l'església, etc i ens van explicar quin nom tenia
cadascuna d'elles i de quins minerals estava composta.
Ens agradar poder fer la sortida i veure les roques que havíem treballat a la classe en els carrers. .

OSMOSI
Hello! We’re the students of 1st Batxillerat and we are going to explain our experiment
about the osmosis.
The osmosis is the process by which two
solutions saparated by a membran tend to equialize.
Here we have the three types of osmosis:
-When the internal solution
has more salt than the external solution. When this happens the cell tale water
from the external solution, that’s very dangerous because the cell swells up and it
can explote (that's almost impossible because of the cellular wall). Here we
have a photo of this procces called turgidity:
-When the internal solution has the same concentration of salt than the
external solution. The cell doesn’t change, here we can see a photo:
