El peix globus
El peix globus
El peix globus se'l situa en els oceans de clima tropical i en la Mar Mediterranea, però ultimament an frequentat la costa catalana. La noticia ha resonat en els medis perque és una espècie que no es pot menjar, a causa de la seva toxicitat per els humans.
La Generalitat confirma la seva presencia i ha donat instruccions als pescadors perquè separin els exemplars capturats.
Desde 2009 fins 2013 només es van registra 5
captures, sabent aquesta dada entenem que és consideri un fet peculiar que
haguin trobat 10 exemplars desde començament d'any.
L'alimentació del peix globus es basa dels invertebrats de closa dura, com els crancs i garotes. És un peix solitari i nocturn.
És important recordar que no es pot menjar, ja que és verinós.

Immersion
Immersion
Introduction
The day 11th of November we did an activity of immersion in the swimming pool of the school with our teacher of 'Vidal Marina' and three people that usually do this activity.
The materials we used to do the immersion course were:
The duration of the whole activity were 2h but each person stayed between 10-15 minutes doing the activity.
The depth of the swimming pool is more or less 1,80m.
The quantity of air that we used is more or less the same as in the street because we were at 1 at.
To unzip, if we are in the sea and we had been diving in a media depth and we have been there for hours, we have to stop while we are going up to expel the nitrogen that our body had caught.
Conclusion
The activity was great because it was funny and interesting but it was a little bit stressing. You had to breathe with the regulator and you also had to control the pressure of the air and the quantity of air you had.

Introduction
The day 11th of November we did an activity of immersion in the swimming pool of the school with our teacher of 'Vidal Marina' and three people that usually do this activity.
The materials we used to do the immersion course were:
- A bottle of compressed air.
- A controller o regulator: it's an object that you put in your mouth to take air of the bottle that has compressed air. There are two regulators, in case your teammate doesn't have more compressed air he or she can take the secondary regulator and use the air of your bottle.
- The jacket.
- Leads.
- Goggles.
- Flippers.
- Wetsuit. In our case swimsuit.
The duration of the whole activity were 2h but each person stayed between 10-15 minutes doing the activity.
The depth of the swimming pool is more or less 1,80m.
The quantity of air that we used is more or less the same as in the street because we were at 1 at.

Introducció al bloc
En aquest bloc en Carles i la Laura volem compartir els nostres estudis sobre la vida al mar.
Sota el nostre punt de vista, el mar és imprescindible per a la vida humana, ja que és una font de recursos, aliment i vida. Pensem que els humans estem alterant l'equilibri dels ecosistemes marins amb les nostres accions.
Amb els nostres estudis ens agradaria que tots fóssim una mica més conscients dels riscos que comporta la nostra despreocupació vers al mar.
