1. Pathways Tool After Before Where is the water?

2. Drivers and Constraints Tool Where does the water start? Where can the water go? What’s the name of process that moves the water? What drives or moves the water? How? What are the constraining factors that affect how the water moves? For example, what affects how fast, how much, or which direction the water moves? Process

7. Tracing Mixtures with Water Tool Substances 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? 2. Tracing Back1. Start Here: The Mixture3. Tracing Forward
