VA BEURE UN DINOSAURE D'AQUESTA AIGUA?
Wells R.
Els dies calorosos no hi ha res més refrescant que un got d'aigua ben freda.
Però, sabies que l'aigua que bevem nosaltres cada dia es realment antiga? Algunes molècules s'han reciclat, no només un cop, sinó milers de vegades! Pot ser que algunes d'aquestes molècules d'aigua hagin estat en un abeurador on anaven a beure els dinosaures ara fa 150 milions d'anys!
Això succeeix perquè l'aigua constantment es renova i neteja mitjançant un gran sistema de reciclatge: el cicle de l'aigua de la Terra. A partir de 7 anys.
