I'm trying to figure out fun ways to teach my students about the states of matter. We're creating a states of matter book and conducting different experiments; however, something that I thought would be interesting for students to complete was a states of matter sorting activity. See my TpT store for a free download of the accompanying homework/independent practice activity that is included in the sorting activity download. Just click on the "download preview" button. For just $1 you can get the sorting activity, plus the independent practice activity that would follow the sorting activity. Thanks for checking it out!
