With this interactive foldable, students are given the definition of a concept and must identify that concept and write it on the backside of the sheet. They then must also draw or write a sentence about how they remember that concept being used in class. The foldable is meant to be folded into four columns where the outside columns get folded inwards. This is meant to be used as a study tool for students completing a science unit on matter. Covers concepts of states of matter, physical/chemical changes, and mass vs. volume.
