Why do scientists say that we all live downstream?
Rain that falls on a hillside flows downhill to streams, then to rivers and lakes. Anything left on the ground, like fertilizer, oil, or litter, can be washed along with it. That means what happens in one place affects another place downhill and downstream. Taking care of the land and storm drains protects the water for neighbors far away.

What Crafty Clover says in this video
Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do scientists say that we all live downstream?
The Big Idea
Scientists say we all live downstream! Even if you live on a hill. What do they mean?
Flowing Down
Step one: Flowing Down. Rain that falls on a hillside flows downhill to streams. Then it flows into rivers and lakes.
Carrying Things
Step two: Carrying Things. Anything left on the ground, like fertilizer, oil, or litter, can be washed along with it. That means what happens in one place affects places downhill and downstream.
Caring
Step three: Caring. Taking care of the land and storm drains protects the water. It helps neighbors far away who live downstream from you.
A Closer Look
Let's take a closer look! Rain falls. Collect it. Carry it. Receives it.
Quick Facts
Quick facts! The area that drains into a lake is called its watershed. Water flows downhill. Spills travel far. We all share water.
Think Like a Scientist
Now, think like a scientist! Crumple a sheet of paper, then flatten it partly. Set it on a tray. Dot it with washable markers. Spray water on top. Trace where the colors flow.
Outro
Rain on a hillside flows downhill to streams, rivers, and lakes, carrying anything left on the ground, like fertilizer, oil, or litter. That means we all live downstream, so caring for the land and storm drains protects water for others. Science is amazing! The world is full of surprises.
