Where is the water?


Pathways tool

Drivers and Constraints Tool

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?

Where does the

water start?

Tracing Mixtures with Water Tool

Substances mix and unmix with water as water moves through systems. How does this work?

2. Tracing Back

1. Start Here: The Mixture

3. Tracing Forward

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?

Where is the mixture?

What kind of mixture is it?

Suspension or Solution

How do you know?

How did the substance get into the water?
