I use these pages for weekly weather/sky tracking in kindergarten.
There are 5 varying pages, each building on the one before it. I use one per grading period. I try to do one per week. But you could mix them up however or do one each week for a unit on the sky/weather.
I model it with the whole class and then they complete their individual ones in their science journal.
Some are better than others, but the point is to OBSERVE AND RECORD CHANGES IN THE SKY AND WEATHER.
