We usually make individual weather graphs for a week and predict the weekend weather. We did this this year but for some reason things got crazy and they didn't get completed the way they usually do.
We always read "Cloudy With a Chance of Meetballs" and then do our own weather forecast writing. This is so fun for the kids to imagine what it would be like if things were raining from the sky.
Then we made some fun foldable trees for our seasons.
