How would I draw an age appropriate graphic organizer on snow for a Pre K classroom?

If it is Pre-K, I suppose you cannot use written words. Otherwise, I would suggest some examples here:

If it has to be pictures only, I would suggest pictures of snowflakes, different winter activities, weather maps during snowy periods etc. , and things to like and not like about snow.
