A flood is a big problem for our planet. It is an overflow of water that submerges land which is usually dry. Flooding may occur as an overflow of water from water bodies such as rivers, lakes or the ocean, in which the water overtops or breaks leeves, resulting in some of that water escaping its usual boundarier, it may occur due to an accumulation of rainwater on saturated ground in an areal flood. Our students have made a flood collage ussing recycle materials and talking about all the consequences of flood for us and for other coutries that suffer this problem with frecuency. It was a very good activity because children were motivated during the challenge and they watched some videos.
