Why is too much road salt a problem?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why is too much road salt a problem?

The Big Idea

Road salt keeps winter streets safe. But too much can cause problems! Where does the salt go?

Washing Away

Step one: Washing Away. When snow melts, salty water washes into storm drains, streams, lakes, and soil. The salt travels far.

Harm

Step two: Harm. Too much salt can harm fish, trees, and drinking water. It also rusts cars and bridges and can make a dog's paws sore.

Smart Salting

Step three: Smart Salting. Cities use the right amounts, spray salty water before storms, or mix in sand. Shoveling early helps, and some places have tried beet juice to help salt work better.

A Closer Look

Let's take a closer look! Salt is spread. It washes into drains. It flows to streams. Fish feel the effect.

Quick Facts

Quick facts! Streams near busy roads can be much saltier in winter than in summer. Wipe dog paws after walks. Shovel early use less salt. Beet juice helps salt.

Think Like a Scientist

Now, think like a scientist! Write three ways a family or school can use less road salt. Share them with your family. Draw the path salty water takes. Start at a road and end at a stream. Add the fish that live there.

Outro

Too much road salt washes into streams, lakes, and soil, harming fish, trees, and drinking water, and rusting cars and bridges. Using just enough and shoveling early helps. Science is amazing!
