🌪️ The Ratio Experiment: Exploring Science Through Sensory Play
*Affiliate link included
In our homeschool, science often starts with play. Whether it’s watching bubbles rise, colors mix, or glitter swirl — hands-on experiments spark curiosity faster than any worksheet ever could.
Our latest setup combined two of our favorite things: sparkle and science. We explored ratios using glitter sensory bottles — discovering how the amount of soap versus water changes how the glitter moves. It’s simple, visual, and filled with that “wow” factor that keeps kids engaged (and calm).
Materials We Used
Clear plastic bottles — we loved using this kit
Warm water
Edible glitter – makes its that much magical
Sequins or confetti (optional for extra sparkle)
Small funnel (optional but helpful)
Super Glue — so lids stay on tight
💡 Tip: Use bottles with secure lids if you plan to add them to your calm-down corner.
🧪 The Experiment: Testing Ratios
Objective
To observe how different ratios of water to soap affect the movement speed of glitter.
Hypothesis
We predicted that bottles with more soap would have thicker liquid, causing the glitter to move slower — while bottles with more water would move faster.
Procedure
Label three bottles — ¼ water, ½ water, and 100% water.
Fill each bottle with warm water to the labeled ratio.
Add clear soap to fill the rest of the space.
Sprinkle in glitter and sequins.
Use different glitter sizes to make the movement easier to see.
Seal the bottles and shake gently.
Observe how the glitter moves.
Does it swirl quickly or slowly?
How long does it take for the glitter to settle?
Results
As we observed:
The bottle with more soap (¼ water) created thicker liquid — the glitter floated slowly.
The ½ water bottle showed moderate movement.
The all-water bottle had the fastest swirl and settled the quickest.
This simple setup shows how viscosity (thickness of liquid) changes how materials move — an early introduction to physics and chemistry!
🧠 The Scientific Process (Made Simple for Kids)
Question: What happens when we change the water-to-soap ratio? “Will the glitter move faster or slower?”
Hypothesis: Make an educated guess. “More soap = slower glitter.”
Experiment: Test your hypothesis with different ratios. ¼, ½, and 100% water bottles
Observation: Watch closely, compare results. “The glitter moved slower in the thicker liquid.”
Conclusion: What did we learn? “The thicker the liquid, the slower objects move.”
💛 Why We Love Sensory Play in Our Homeschool
Sensory play isn’t just fun — it’s foundational.
When kids engage multiple senses, they activate more areas of the brain, which strengthens memory, focus, and emotional regulation.
Research shows that hands-on, sensory-rich activities:
Improve fine motor skills and hand-eye coordination
Encourage problem-solving and critical thinking
Support language development as kids describe what they see and feel
Build emotional awareness, helping children self-regulate through calming tactile input
According to a 2020 study published in Frontiers in Psychology, sensory play “provides a bridge between concrete experience and abstract thinking,” helping children better understand scientific and mathematical concepts through real-world interaction.
In other words — every glitter swirl is a mini science lesson in motion.
✨ Extending the Learning
Math Connection: Graph the glitter’s settling time for each bottle.
Language Arts: Have your child describe what they see using vivid adjectives.
Mindfulness: Use the slow-moving bottles in your calm-down corner as a visual regulation tool.
📸 Our Takeaway
In our home, the goal isn’t perfect experiments — it’s sparking curiosity.
When learning feels like play, kids naturally ask more questions, make connections, and stay engaged longer.
These glitter bottles reminded us that even the simplest setup can be full of wonder — and that the best learning moments happen when we join in, not just observe.
