En l\u2019optativa de Cultura Cient\u00edfica de 3r d\u2019ESO estem treballant l\u2019alimentaci\u00f3 sostenible i saludable. Un dels treballs que hem fet al respecte ha estat fer un experiment sobre les conseq\u00fc\u00e8ncies nefastes que t\u00e9 la pluja \u00e0cida sobre els conreus. Aquest fenomen est\u00e0 provocat pels productes qu\u00edmics que alliberen les f\u00e0briques i els cotxes, i que es combinen amb l\u2019aigua atmosf\u00e8rica produint \u00e0cids que queden dissolts en les gotes d\u2019aigua que precipiten quan plou, contaminant els conreus i afectant al creixement de les plantes.<\/p>\n

L\u2019experiment consistia en fer simulacions de germinacions i creixements de 4 llavors diferents (llentia, mongeta blanca, quinoa i cigr\u00f3) en condicions normals i en condicions de pluja \u00e0cida, amb diferents dissolucions de disulfit de sodi. El disulfit despr\u00e8n di\u00f2xid de sofre que combinat amb l\u2019aigua formen \u00e0cid sulf\u00faric. Els resultats van ser clars: en condicions de pluja \u00e0cida les llavors creixien m\u00e9s lentament o directament no creixien.<\/p>\n
