Tracing Mixtures with Water ToolSubstances mix and unmix with water as water moves through systems. How does this work?
Where did the substance come from? What’s mixed in the water? 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?
Where did the water come from?
How did the substance get into the water?
Where is the mixture?
What kind of mixture is it?Suspension or Solution
How do you know?
