You can take your children out to watch a sunset and if they are older a sunrise since it is to early in the morning for most younger children. Tell them to watch and not talk, I know hard for some of the younger ones but be patient and they will learn to be patient also. When the sun is gone and most of the colors have faded sit still and talk to the children about what they saw, but let them do most of the talking. I have found that if I just sit and listen to my children I will hear the most wondrous things. They are so full of imagination and innocence.
Then you can say a small prayer either to greet or say farewell to the sun.
Rest well and rise upon the morn
Merry Meet and Merry Part
Greetings to the Sun
Rise quickly and banish the night
Light our path in the day ahead
Hail and Blessed Be
I hope that these things have sparked your interest and perhaps you will take the time out to show your children or perhaps just look yourself at the wonders of nature that are revealed around us all the time.
