Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How can scientists measure snow in inches of water?
The Big Idea
Scientists can measure snow in inches of water because snow is mostly air. They find out how much water is hidden inside the snow. This is called snow water equivalent.
Why Not Just Measure Depth?
Step one: depth is not enough. Fluffy snow is mostly air, so a deep pile may hold very little water. Wet, heavy snow holds more water than fluffy powder.
Weigh the Snow
Step two: scientists weigh the snow. They push a tube into the snow and weigh the core. Or they use a special pillow that weighs the snow lying on top of it.
Turn It Into Inches
Step three: they turn weight into water. Ten inches of fresh snow often equals about one inch of water. Water managers use these numbers to predict how much water will flow in the spring.
A Closer Look
Let's take a closer look at snow water! First, scientists measure how deep the snow is. Then they push a tube into it. They weigh the core of snow it collects. And that tells them how much water is inside.
Quick Facts
Quick facts! Ten inches of fresh snow often equals about one inch of water. Wet, heavy snow holds more water than fluffy powder. A pillow can weigh the snow lying on top of it. Water experts use the numbers to plan for spring.
Think Like a Scientist
Now, think like a scientist! Scoop a cup of fresh snow, and let it melt indoors. Measure the water that you get. How much water did one cup of snow make? Compare it with a friend's cup.
