Will the pupils guess what substance is in each test-tube? We will see...
Lloc de trobada pels que tenim curiositat i ens agrada la CIÈNCIA i la seva DIVULGACIÓ, sobretot a les aules de l'ESO. Hi trobareu activitats, pensaments, projectes, vídeos, pràctiques... sorgits del dia a dia a les classes, d'emails, de converses i d'altres formes de COMUNICACIÓ. Potser se'ns obrirà alguna porta, o ens confondrà, o ens ajudarà en el camí, o ens farà dubtar... és a dir, LA VIDA. Tu també pots aportar el que vulguis, siguis de l'espècie que siguis. twitter.com/lapomadenewton

Acid and base challenge: what is there inside the test-tubes?
Pupils from 4th Physics and Chemistry went to the lab and found 6 test-tube with 6 mysterious substances. They have to guess which substance is in the 6 test-tubes from a list of 12 by using red cabbage juice for knowing if it's an acid or a base (or even a neutral substance) and using litmus paper for having an approximation of its pH.
