How can you make the most of snow days while keeping your high school science students engaged? When snow starts falling and the world turns into a winter wonderland, it’s the perfect opportunity to jump into some creative and hands-on science snow day activities. Snow days don’t have to mean a pause in learning—they offer a chance to bring science to life in ways that are both fun and educational.
From exploring the crystallization of snowflakes to how salt affects freezing point depression, these 10 snow day activities for high school science are designed to spark curiosity and keep students thinking critically about the science behind the snowy season.
1. Frozen Bubble Experiment
The frozen bubble experiment is a fun, hands-on activity that lets students observe science concepts like freezing point, crystallization, and surface tension, and other properties of water in action. It’s also highly visual and engaging, and one of my favorite snow day activities! Here’s how to conduct the experiment:
Materials Needed:
- Bubble solution (store-bought or homemade: mix 1 part dish soap, 4 parts water, and 1 part glycerin or corn syrup for stronger bubbles)
- A bubble wand
- A flat, cold surface (e.g., a metal pan, a piece of glass, or snow)
- Freezing temperatures (below 32°F / 0°C)
- Optional: A straw for more controlled bubble placement
Instructions:
- Preparation:
- If you’re indoors, chill the bubble solution in the freezer for about 10-15 minutes to make it colder.
- Make sure the outdoor temperature is well below freezing for optimal results.
- Choose a calm day with little wind to avoid popping the bubbles prematurely.
- Blowing the Bubbles:
- Take the bubble solution and wand outside or near a cold window.
- Gently blow a bubble and let it settle on a cold surface like snow, ice, or a metal pan. If you’re using a straw, dip it into the solution and blow slowly to release the bubble.
- Watch the Freezing Process:
- Observe as the bubble begins to freeze. Ice crystals will form on the bubble’s surface, spreading in beautiful patterns. This happens because the soap film loses heat quickly in the freezing air.
- If the temperature is extremely cold (e.g., below -10°F / -23°C), the bubble might freeze almost instantly.
- Capture the Moment:
- Look for patterns like feather-like crystals or swirls on the bubble. These are caused by the rapid crystallization of water molecules.
- If you’re working with students, ask them to sketch or describe what they see.
- Optional Experimentation:
- Try blowing bubbles of different sizes and observe whether they freeze at the same rate.
- Experiment with different surfaces (metal, glass, snow) to see how they affect the freezing process.
- Introduce variables like adding sugar or salt to the bubble solution and compare the results.
- Watch a time-lapse of bubbles freezing before or after the experiment!
Scientific Explanation:
When the bubble is exposed to sub-freezing temperatures, the water in the bubble solution freezes first, forming intricate ice crystals. The soap and glycerin help stabilize the bubble’s structure, making it possible to observe the freezing process without it popping immediately.
2. Ice Cube Insulation Challenge
The Ice Cube Insulation Challenge is a simple yet engaging snow day experiment that helps students explore how different materials provide insulation and prevent heat transfer. This activity is perfect for teaching concepts like thermal conductivity, insulation, and energy transfer, and it’s adaptable for both in-person and virtual learning.
Materials Needed:
- Ice cubes (same size for consistency)
- A variety of insulating materials (e.g., cotton, aluminum foil, wool, plastic wrap, paper, and Styrofoam)
- Small containers or cups to hold the materials
- A timer
- A thermometer (optional, for temperature readings)
- Paper and pen for recording results
Instructions:
- Set Up:
Start by placing a single ice cube inside each small container or cup. Surround each ice cube with a different insulating material, making sure it is evenly packed around the cube. Leave one ice cube uncovered as the control. Label each container to keep track of the materials being tested. - Conduct the Experiment:
Place the containers in a room at room temperature or slightly warm conditions. Start a timer and observe how long it takes for the ice cubes to melt. To add a quantitative element, students can periodically measure the remaining volume or mass of the ice cubes using a scale or by carefully draining the melted water. - Record and Analyze Results:
Encourage students to record their observations, noting which materials kept the ice cube frozen the longest. Discuss the properties of the best insulating materials and relate them to real-world examples, such as insulation in buildings or clothing for cold weather.
This challenge not only makes thermal energy concepts tangible but also introduces students to experimental design, data collection, and analysis. It’s a fun and interactive way to demonstrate how insulation works and why it’s crucial in both natural and engineered systems!

6. Melting the Ice: Exploring Freezing Point Depression with Salt
In this hands-on activity, students explore the concept of freezing point depression by experimenting with salt and ice. They’ll measure how adding salt lowers the freezing point of water, making it harder for ice to form or remain solid. Through this investigation, students connect the science to real-world applications, learning why salt is commonly used on roads during icy snowstorms to melt ice and prevent dangerous conditions.
Materials Needed:
- 2 small clear cups or bowls per group
- Ice cubes
- Table salt
- Thermometer
- Water
- Timer
- Optional: Sand (for comparison to salt)
Directions:
- Set Up: Fill one cup with ice cubes and water, creating an ice-water mixture. Repeat with a second cup.
- Control Group: Label the first cup “Control.” Do not add anything to this cup.
- Experimental Group: Label the second cup “Salted.” Add 2-3 teaspoons of table salt to the ice-water mixture. Stir gently for a few seconds.
- Measure Temperature: Use a thermometer to measure the temperature of both mixtures at the start and record the values.
- Observe and Record: Every 2-3 minutes for the next 10-15 minutes, measure and record the temperature of both cups.
- Optional Comparison: If using sand, repeat the same process with a third cup containing sand instead of salt.
- Analyze Results: Compare the temperature changes between the control, salted, and sanded mixtures.
- Discussion: Discuss how salt lowers the freezing point of water and why it’s effective for melting ice on roads during snowstorms. Highlight why sand, while not lowering the freezing point, is sometimes used for traction.
This activity is a perfect way to illustrate the practical use of chemistry in everyday life and helps students understand how freezing point depression works to improve safety in winter conditions.
