❄️ Introduction
When the temperature drops, curiosity doesn’t have to cool down. Snow Much Fun brings the wonder of winter indoors with creative, low-prep STEM challenges for little scientists and engineers. These activities combine real-world discovery with play-based exploration—perfect for classrooms, homeschool setups, or cozy afternoons at home.
Grab your goggles (and maybe some mittens)—we’re diving into five snow-inspired STEM projects that are as fun as they are educational!
🧪 1. The Melting Race: Salt vs. Sugar Science
Concepts: States of matter, chemical reactions, temperature
You’ll Need:
Ice cubes (frozen in silicone molds for variety)
Salt and sugar
Droppers and warm water
Thermometer (optional)
How to Play:Set up two trays of ice. Sprinkle one with salt and one with sugar. Have children hypothesize which will melt faster, then test their prediction. Use droppers to add warm water and record the results.
Shop the Setup:Instant Snow Science Kit, Silicone Ice Molds, Learning Resources Droppers, STEM Experiment Trays
🧊 2. Build-a-Snow-Bridge Challenge
Concepts: Engineering, balance, weight distribution
You’ll Need:
Marshmallows (mini and jumbo)
Toothpicks or craft sticks
Small toy figures (to “test” the bridge)
How to Play:Challenge kids to build a bridge strong enough to hold their toy figure using only snow-like materials (marshmallows and toothpicks). Test and rebuild—engineering is all about iteration!
Shop the Setup: Mini Marshmallows, Plastic Toothpicks
💨 3. Blizzard in a Bottle
Concepts: Density, reaction, and observation
You’ll Need:
Clear plastic bottles
Baby oil
White paint
Alka-Seltzer tablets
Glitter or sequins
How to Play:Mix water, paint, and glitter in the bottle, then fill the rest with baby oil. Drop in Alka-Seltzer to create a swirling “blizzard.” Encourage kids to describe what’s happening inside their mini storm.
Shop the Setup:STEM Discovery Bottles, Non-Toxic Glitter Set, Antacid tablets
🧤 4. Snowflake Structures
Concepts: Geometry, symmetry, engineering
You’ll Need:
Cotton swabs
Scissors
Glue
Blue construction paper
How to Play:Cut and arrange cotton swabs into symmetrical snowflake designs. Discuss patterns, geometry, and how nature forms repeating shapes.
Shop the Setup:Cotton Swabs, Glue or Glue Dots, Winter Paper Pack
🌬️ 5. The Frozen Float Test
Concepts: Buoyancy, density, prediction
You’ll Need:
Variety of small items (buttons, toy animals, foil, plastic lids)
Ice cube tray or bin
Warm and cold water bowls
How to Play:Freeze each object in an ice cube. Let kids predict which cubes will sink or float when placed in water. Observe how density affects buoyancy as they melt!
Shop the Setup:Learning Resources Primary Science Deluxe Lab Set, Learning Resources A-to-Z Mini Foods, Jumbo Tweezers or Handy Scoopers
🌈 Wrap-Up
STEM play doesn’t require fancy labs or expensive tech—just a spark of curiosity and a few household materials. These winter-inspired projects help children explore cause and effect, test predictions, and develop the persistence that every great scientist needs.
So next time the world outside looks like a snow globe, bring the magic indoors. Science is everywhere—it just takes a curious kid to see it.
