A Simple Winter Science Experiment for Kids
Explore Snow, Weather, and the Water Cycle at Home or School
Winter weather offers the perfect opportunity for hands-on science learning. The Snow-to-Water Ratio Lab is a simple, engaging experiment that helps students understand how snow relates to rainfall, water supply, and weather patterns. Best of all, it uses everyday materials and works just as well in a backyard as it does on a school campus.
This activity is ideal for elementary and middle school learners and directly connects to topics such as states of matter, measurement, weather, and the water cycle.
What Is the Snow-to-Water Ratio?
The snow-to-water ratio compares how much snow falls to how much liquid water it produces when melted. While a common estimate is that 10 inches of snow equals 1 inch of rain, the actual ratio varies depending on temperature and snow type. This experiment allows students to investigate that variation for themselves.
Supplies
- Clear cup, jar, or container
- Ruler or measuring tape
- Marker or tape
- Spoon or scoop
- Paper and pencil
Step-by-Step Instructions
- Take an empty, clear container outside and fill it loosely with fresh snow. Do not pack it down.
- Use a marker or tape to mark the snow level on the cup.
- Bring the container indoors and allow the snow to melt completely.
- Measure the depth or volume of the melted water.
- Calculate the snow-to-water ratio using this formula:
- Snow depth ÷ Water depth = Snow-to-water ratio
- Example: 4 inches of snow results in 0.25 inches of water
- 4 ÷ 0.25 = 16; The snow-to-water ratio is 16:1.
- Record results and observations.
Extend the Learning
- Compare results from different snowfall events.
- Test snow collected from sunny vs shaded areas.
- Graph class results to look for patterns.
Why This Experiment Works
Students learn that snow is mostly air and that weather conditions affect snowfall density. This activity also builds skills in data collection, math, and scientific observation, making it a strong cross-curricular lesson.
