After completing notes on the phases of matter this mini lab is a great way to assess what your students know. In the quiz they must decide what the solid, liquid, and gas is in the root beer float. You can give them real ones or just show a picture! I made mini ones in my class with little bathroom cups. They must also be able to define what matter and mass are. In sixth grade in Virginia students are introduced to the final phase of matter plasma. They must state this fourth phase and an example of it. I hope you enjoy!
