U jednu prozirnu čašicu za kavu ulijte mlijeko , a u drugu kavu i ostavite ih na suncu .Nakon pola sata termometrima izmjerite temperature tekućina 
Ustanovit ćete da termometar u kavi pokazuje veću temperaturu.

ZAKLJUČAK: Tamna i hrapava tijela jače upijaju sunčevo zračenje, nego svijetla i glatka tijela.]]> 2018-05-14 13:52:50 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260468910 Učinak staklenika ankicajajas https://padlet.com/dujeseneta/35a67ed9tl77/wish/260510455 2018-05-14 15:17:18 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260510455 ankicajajas https://padlet.com/dujeseneta/35a67ed9tl77/wish/260517300 Uzgajanje biljaka u staklenicima]]> 2018-05-14 15:30:53 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260517300 Način na koji rade ankicajajas https://padlet.com/dujeseneta/35a67ed9tl77/wish/260517992 1.Tlo i biljke u stakleniku upijaju Sunčevu energiju 2.Zagrijavaju se 3.Zrače toplinu koju staklo slabo propušta,a temperatura se povećava]]> 2018-05-14 15:32:19 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260517992 Važnost učinka staklenika ankicajajas https://padlet.com/dujeseneta/35a67ed9tl77/wish/260520312 Ugljikov dioksid u atmosferi djeluje kao staklo u staklenicima         1.Ugljikov dioksid propušta  sunčeve zrake    2.Zemlja se danju grije,noću hladi                    3.Dio topline odlazi u svemir,dio ostaje u atmosferi                              ]]> 2018-05-14 15:36:53 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260520312 Posljedica ankicajajas https://padlet.com/dujeseneta/35a67ed9tl77/wish/260525625 Globalno zatopljenje]]> 2018-05-14 15:47:34 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260525625 patriciabulat1 https://padlet.com/dujeseneta/35a67ed9tl77/wish/260939523 2018-05-15 17:12:17 UTC https://padlet.com/dujeseneta/35a67ed9tl77/wish/260939523 Primjer patriciabulat1 https://padlet.com/dujeseneta/35a67ed9tl77/wish/260943882 npr.
