About Matter Sorter

You know the “states of matter”, right? Solid, liquid, gas…. and plasma? Test your knowledge by sorting the falling objects into the appropriate bins. Be careful though: you’re only allowed a few mistakes, and each level will be faster than the last.

For teachers: You can use this with middle school science units on the states of matter. We’ve had reports of teachers projecting this activity, with students shouting out the answers.
