Choose two different areas in Dallas-Fort Worth: one with grass or soil, and the other with pavement or concrete.

Pour a cup of water onto each surface and observe what happens.

Does the water soak into the ground, or does it run off the surface? Which area holds more water?

Which surface dries up faster? Compare how the surfaces react to the water over time. You can use a stopwatch, smartphone or count yourself!

Think about how this affects plants, animals, and even flooding in the city. How might rain gardens or green spaces help absorb water?

After completing your observations, share how different surfaces impact water absorption and how urban areas can benefit from more green spaces.
