I created this Atoms and Molecules Sorting Center and Recording Sheet to help students practice identifying between atoms and molecules using definitions, symbols and pictorial representations. Teacher and Student Directions are included. This is a center that can be made and reused indefinitely! Teachers just need to copy a class set of the recording sheet. Also, look for my Atoms and Molecules cut and paste sorting activity worksheet, as well as a center and worksheet for Elements and Compounds as well! Enjoy!
