It seems that we get one or two days of pleasant weather then several of cold and wet. I don't mind wet. I expect wet in spring but I do not like the inconsistent temperature changes. It is difficult to follow through with the lessons at times, simply because so much of what I plan for science this time of year goes outside.
We tend to "do science" in the nice months. When we do experiments then we can be out on the back deck and not worry about the mess or if we finish it up for the day. Material can be protected and the clutter is not part of the house.
