Els alumnes de la mat\u00e8ria de F\u00edsica i Qu\u00edmica de 2n d\u2019ESO han realitzat una pr\u00e0ctica de laboratori centrada en la preparaci\u00f3 de dissolucions i l\u2019expressi\u00f3 de les seves concentracions de diferents maneres. Aquesta activitat ha perm\u00e8s als estudiants aprofundir en conceptes fonamentals com la solubilitat, la concentraci\u00f3 i les diferents formes d\u2019expressar-la, com ara la concentraci\u00f3 en massa i els grams per litre.<\/p>\n

L\u2019experiment s\u2019ha dut a terme al laboratori de l\u2019institut, on els alumnes han preparat dissolucions amb diferents subst\u00e0ncies i han apr\u00e8s a calcular la seva concentraci\u00f3 amb precisi\u00f3. Amb l\u2019ajuda de balances, provetes i altres materials de laboratori, han pogut comprovar com varia la concentraci\u00f3 en funci\u00f3 de la quantitat de solut i dissolvent utilitzats.<\/p>\n

C<\/strong>i\u00e8ncia aplicada a la vida quotidiana<\/strong><\/h3>\n

Un dels aspectes m\u00e9s interessants de l\u2019activitat ha estat la connexi\u00f3 amb la vida quotidiana. Els alumnes han descobert que les dissolucions s\u00f3n presents en molts aspectes del dia a dia, com ara en begudes, medicaments o productes de neteja. Aix\u00f2 els ha ajudat a veure la import\u00e0ncia de la qu\u00edmica m\u00e9s enll\u00e0 del laboratori.<\/p>\n
