Hey, teachers! Winter might mean indoor recess and extra layers, but it’s also the perfect time to bring some snowy science fun into your classroom! Whether you live in a winter wonderland or a place where snow is just a dream, these easy, hands-on snow-themed science experiments will engage your students and spark curiosity.
The best part? No real snow required (though if you have it, even better)! Let’s dive into some cool (literally) science experiments that will make your classroom feel like a winter wonderland.
1️⃣ Instant Snow – Is It Magic or Science? 🌨️
Ever wanted to make snow appear out of nowhere? Well, here’s a super simple science experiment that lets your students create their own instant snow!
What You Need:
- Instant snow powder (found online or at craft stores)
- Water
- A clear plastic container
What to Do:
- Pour a small scoop of instant snow powder into the container.
- Slowly add water and watch the snow expand instantly!
- Let students touch and explore the fluffy, cool snow.
The Science Behind It:
The instant snow is made from a superabsorbent polymer (like the material in baby diapers). It soaks up water and expands 100 times its size, creating a fluffy, snow-like substance. No frostbite included!
👉 Extension: Test what happens if you add cold vs. warm water—does the snow behave differently?
2️⃣ The Melting Race: What Makes Snow Melt Fastest? ☀️ vs. ❄️
This one is great for introducing states of matter and conducting simple experiments on melting points!
What You Need:
- Real snow (or instant snow)
- Salt
- Sugar
- Sand
- Warm water
- 4 clear cups
What to Do:
- Fill each cup with the same amount of snow.
- Sprinkle salt in one, sugar in another, sand in the third, and leave the last one as a control.
- Observe which one melts the fastest and slowest over time.
- Record findings and discuss why some materials speed up melting!
The Science Behind It:
Salt lowers the freezing point of water, causing snow to melt faster (which is why we use it on icy roads). Sugar also affects the melting process, but differently than salt. Sand, on the other hand, absorbs heat, which helps speed up melting too!
👉 Extension: Try different materials like baking soda or vinegar to see how they compare!
3️⃣ Frozen Bubbles – Watch Ice Crystals Form! 🫧❄️
If you’ve ever blown bubbles in the freezing cold, you might have noticed something magical—they freeze into ice globes! Let’s recreate that!
What You Need:
- Bubble solution (store-bought or homemade)
- A straw or bubble wand
- Freezing temperatures (below 32°F / 0°C)
What to Do:
- Head outside on a freezing day and blow bubbles into the cold air.
- Watch as the bubbles freeze in midair and turn into delicate ice spheres!
- If it’s not cold enough outside, try placing a pan of bubbles in the freezer and observe what happens.
The Science Behind It:
Bubbles are thin layers of water and soap molecules. When exposed to freezing temperatures, the water in the bubble crystallizes, creating beautiful ice patterns. The colder it is, the faster they freeze!
👉 Extension: Try using different bubble solutions (homemade vs. store-bought) and see if they freeze differently!
4️⃣ Snowstorm in a Jar – A Blizzard You Can Control! 🌪️❄️
Want to bring a blizzard indoors without the cold? This experiment creates a swirling snowstorm effect inside a jar!
What You Need:
- A clear jar (mason jar or plastic bottle)
- Baby oil
- White paint + water (or Alka-Seltzer for a bubbling effect!)
- Glitter (optional, but fun!)
What to Do:
- Fill the jar 3/4 full with baby oil.
- Mix white paint with water in a separate cup, then pour it into the jar.
- Drop in small pieces of Alka-Seltzer and watch the storm swirl!
The Science Behind It:
The baby oil and water don’t mix (density difference), and the Alka-Seltzer creates a chemical reaction that makes the “snow” swirl like a real winter storm!
👉 Extension: Add blue food coloring for a “snowy night” effect!
5️⃣ Grow Ice Like Elsa – Supercooling Water!
This is one of the coolest science tricks—turning liquid water into ice instantly!
What You Need:
- Purified water (bottled water works best!)
- A freezer
- A small bowl
- An ice cube
What to Do:
- Place a sealed bottle of purified water in the freezer for 2-3 hours.
- Carefully remove it (without shaking it too much).
- Slowly pour it over an ice cube in a bowl—and watch it freeze instantly!
The Science Behind It:
This experiment works because the purified water is “supercooled”, meaning it’s below freezing temperature but hasn’t turned into ice yet. When you pour it over an ice cube, the ice crystals form instantly like magic!
👉 Extension: Try using tap water vs. bottled water—does one work better?
