How do snowplows and salt trucks clear the road?
A snowplow has a big angled blade that pushes snow to the side. Many also spread salt or sand from the back. Crews watch the weather and plan routes with GPS so they can clear major roads first. Small plows clear sidewalks and bike paths. Stay far away from plows, since the drivers might not see you, and never play in the snow piles.

Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do snowplows and salt trucks clear the road?
The Big Idea
After a snowstorm, the plows roll out! They clear the roads so people can travel. Let's see how.
The Blade
Step one: The Blade. A snowplow has a big angled blade that pushes snow to the side. The angle sends snow off the road.
Salt and Sand
Step two: Salt and Sand. Many plows also spread salt or sand from the back. Salt helps melt ice, and sand gives tires grip.
Planning
Step three: Planning. Crews watch the weather and plan routes with GPS so they can clear major roads first. Small plows clear sidewalks and bike paths. Stay far from plows, and never play in snow piles.
A Closer Look
Let's take a closer look! Big plows clear roads. Salt melts ice. Small plows clear sidewalks. GPS plans routes.
Quick Facts
Quick facts! Some plows have wings to clear extra lanes. Never play in snow piles. Drivers may not see you. Main roads first.
Think Like a Scientist
Now, think like a scientist! Push a toy plow through flour or sand. Try a straight blade first. Then try different angles. Watch where the pile goes. Which angle cleared best?
Outro
Snowplows clear roads with big angled blades that push snow aside, and many spread salt or sand. Crews plan routes with GPS. Stay far away from plows and snow piles. Science is amazing!
