"Children, this year the north has ushered in the first snow since the beginning of winter. When it snows, we all like to play snowball fights and build snowmen outside, and have a great time. We all know that when it is really cold, it is when we learn to melt. At this time, the ice and snow slowly melt and absorb heat, and we all feel that the temperature in the air is much lower than when it snows.
