How does this work? 2. Tracing Back 1. Start Here: The Mixture Where did the substance come from? What’s mixed in the water? Where did the water come from? Where is the mixture? How did the substance get into the water? What kind of mixture is it? Suspension or SoluDon How do you know? 3. Tracing Forward If the water moves (new place) ___________________, will the substance stay mixed with the water? YES or NO If NO, how and why will it separate? If YES, why will it stay mixed?
