Mixtures and solutions. Lab practices 1.

After a while (¿?), we leave here some examples of the laboratory practices (filtration and magnetic separation) and their presentations that the 2nd ESO students did not so a long time ago.

Cristalls de sulfat de coure

Els alumnes de 3r hem fet una pràctica al laboratori que consitia en purificar una substància anomenada Sulfat de Coure.
En primer lloc hem hagut de fer una disolució saturada del producte que vol dir que hem hagut de disoldre tant sòlid com hem pogut en 50 ml d’aigua.

  Per ajudar-nos una mica hem escalfat l’aigua ja que així es dissol millor.



 Hem filtrat la disolució …..

Hem deixat que s’evapori lentament ...

I ens hem trobat que ha cristal.litzat!!!!!!! 
S’han format aquests cristalls tan bonics!!!!!

Mould garden (and more)

Maybe you wonder... what are they observing???

The answer is easy: our mould garden!
Enjoy it!


and also some lichens we add at the last moment...

And last but not least, a video on the notion of SYMBIOSIS, that kind of relationship we find in lichens (between a fungi and an alga) or, as we saw in Cosmocaixa, in termits (between them, remember, and some protozoa and some bacteria).
