May I also suggest that you check with your local National Weather Service Station. When I homeschooled my children (they are both in their 20s now), we became weather observers for the NWS in Jackson, KY. They visited and put up a not only a rain gauge, but also a temperature gauge. We began reporting daily temperatures, amount of precipitation, and other weather phenomena that occurred. Now that my kids are no longer schooling, I have taken over as the weather observer. It is truly enjoyable thing to do.
