A Great Website: neoK12
If you haven't already discovered this website, I think you will bookmark it for the future! Wow! There is a wealth of information and activities here. It contains online educational videos, lessons, games, puzzles, and quizzes for students in grades K-12 although the section on matter is mostly for Grades 3 - 12. It also includes the 4th state of matter (plasma).The link below will take you to the section that is all about the STATES of MATTER. Have fun!
