Go on a neighborhood explore...
Talk about the light and how it shines on the snow.
Look for things that are frozen. Can you find ice that is in the process of melting because of the sunshine? Is there ice that has melted and has frozen again overnight?
Shadows! Make shadows on the snow and then on the grass. How are they the same and how are they different?
Snow on the mountains. Ask questions. Why does it stay on the mountains even though it is sunny today? Why does it melt on the street but not on the grass?
Look for snow sculptures, snow people, snow forts. Can you find tracks in the snow where people, dogs, cats and birds have walked on it. Do you see tracks from sleds and from rolling a ball in the snow?
Measure the snow. Is there more snow in the shade? More snow under a bush? Do you see snow on the roof of a house?
Enjoy a walk through the neighborhood on a sunny snow day.
