I've been struggling to teach my little ones the different states of matter. They have done well with solids and liquids but we're still struggling with gases. So I started researching on the web and other blogs and haven't found much to help. We did have a science assembly at the beginning of the year and the lady did a nice job teaching the concept. Too bad that the kids can't remember any of it. One of the things that she did was bring 3 different color balloons. One was filled with air, one was filled with liquid and one was filled with cornstarch. Here is a pocket chart sort that I made to help my kids. Hope someone find it useful.
I'll post some more community helper activities tomorrow.
