Stormwater Runoff Project For Kids

What happens to rain or melting snow when it can’t go into the ground? Set up an easy stormwater runoff model with your kids to demonstrate what happens. Get them talking about how they can help reduce runoff pollution. A great project for Earth Day!

LEARN ABOUT STORMWATER RUNOFF FOR EARTH DAY

WHAT IS STORMWATER?

Stormwater is rainwater or snowmelt plus anything the rain carries along with it. Stormwater is also known as ‘polluted runoff’.

Stormwater runoff is created by rain or melting snow that flows over the ground. In cities, stormwater runs over streets and parking lots, picking up oil and other pollutants before flowing into rivers or streams.

Why is stormwater runoff a problem?

When rainwater can’t soak into the ground in urban areas because of pavement, the water is forced to run along streets and parking lots, picking up pollutants.

Stormwater runoff can contain chemicals, paint, building construction waste, fast food packaging, cigarette butts, cooking oil, car oil, animal waste, etc.

This stormwater runoff pollution can flow into our streams and rivers, and into the ocean affecting marine life.

In farming areas, stormwater runoff can push excess nutrients from fertilizers and other pollutants into waterways, which leads to algae blooms.

Heavy stormwater runoff can also overwhelm infrastructure and cause sewage overflows, as well as cause soil erosion to stream banks and rivers.

How do you reduce stormwater runoff?

You can help prevent stormwater pollution in your own backyard by reducing runoff into local stormwater drains. Wash your car on the lawn instead of the driveway, and keep leaves, grass clippings and soil from going into drains.

In the street, pick up pet droppings and other litter and dispose of them in a garbage bin.

On the land, re-plant areas that have been affected by soil erosion, and add plants to the banks of rivers and streams. Support a reduction in the use of fertilizers and pesticides through organic farming.

Let’s make stormwater runoff clean and keep pollutants out of our waterways!

STORMWATER RUNOFF MODEL

Let’s explore the impact of stormwater runoff by building a model! This is a great hands-on STEM activity that is sure to get kids thinking!

This stormwater runoff project asks a few questions!

What is stormwater runoff?
What causes stormwater runoff pollution?
How can we prevent or reduce stormwater runoff pollution?

Let’s explore the answers together!

SUPPLIES:

Paint tray or baking pan
Printable Stormwater Runoff Worksheet
Markers
Tape
Water bottle
Pollutants – Oil, chocolate, frosting, shaving cream, salt, sand etc.

INSTRUCTIONS:

STEP 1: Print the stormwater runoff worksheet and color it in. Cut out the pieces.

STEP 2: Tape the images to your paint tray or a baking pan.

STEP 3: Place the substances on the tray you have chosen to represent oil, chemicals, and animal excrement.

STEP 4: Add clean water to the bottom of your tray or pan.

STEP 5: Use spray bottle to represent the storm water runoff during a rain storm.
