What you will Need for Building Marble Tracks

Marbles

Pipe cleaners

Building blocks or large Lego's

A washcloth

Tape

Plastic wrap

What To Do

Step one: Build a marble track with your pipe cleaners and blocks for your marbles. You will need two pipe cleaners on each side of the marble track. You're creating a track for them. It helps if you tape your pipe cleaners down to the ground so the marbles don't dislodge them, but you will need to make sure the tape won't halt the marbles' progress. A little bit of tape will go a long way with this.

Step two: Create a slide using two pipe cleaners, your plastic wrap and Lego's. Wrap t plastic wrap around the pipe cleaners for the best effect. Again, a little will go a long way. To see a picture, check out my science and nature blog.

Step three: To illustrate friction, try building your pipe cleaner track across the washcloth. Push a marble across it and show your preschooler how much the washcloth slows the marble down.

Step four: Have some fun with this. Build tracks across your kitchen table, across your kitchen floor or wherever you can imagine. Let your preschooler play with the marbles and pipe cleaners. The tracks they build won't work perfectly, but they will get the idea of the process. While your tracks won't work perfectly unless you have a degree in engineering, your preschooler will have a lot of fun just building the tracks and they will get a basic understanding of preschool physics topics.

Helpful Tips

Use larger marbles, rather than smaller marbles.

You may find your tracks work better if you cut your pipe cleaners in half.

The less your pipe cleaners have been played with and the straighter they are, the better your marble tracks will work.

Hi! I'm Theresa Halvorsen, the preschool science and nature writer for Preschoolrock.com. I have twin boys and am blown away by their fascination with preschool science and how the world works around them. I am always looking for fun and simple science activities so preschoolers can learn about science and the natural world. Please contact me with any suggestions, ideas or questions you have about this site.

Helpful Tips for Parents

• Document seasonal science observations over months and years. A child who tracks the same tree across four seasons has done longitudinal observational science — genuinely impressive.

• Always ask "What do you think will happen?" before running an experiment. Prediction is the core of scientific thinking, and preschoolers' predictions are always worth hearing.

• Repeat experiments multiple times. Reliability — the same result happening consistently — is a key scientific concept, and repetition gives preschoolers the proof they find satisfying.

• Science is everywhere: the kitchen, the garden, the bathroom, the driveway. Narrating daily life as science keeps curiosity active between formal experiments.

Frequently Asked Questions

What everyday household materials are best for preschool science?

The essential preschool science pantry: baking soda, white vinegar, cornstarch, salt, sugar, food coloring, dish soap, and water. These materials enable: acid-base chemistry (baking soda + vinegar), non-Newtonian fluids (cornstarch + water = oobleck), color mixing (food coloring), surface tension (dish soap), crystal growing (salt and sugar), and density experiments (sugar solutions). Beyond kitchen supplies: magnets, a flashlight, a magnifying glass, and ice are the other essentials. The best science lab is an accessible kitchen shelf.

How do I build a child's science confidence when they get frustrated by unexpected results?

"Unexpected" is the word to use rather than "wrong" — in science, results that don't match predictions are the most interesting. "The result was different from what we expected — that means we discovered something! Let's figure out why." This reframe makes the unexpected result a success rather than a failure, because it produced a question worth investigating. Science confidence is built by treating all results as valid data, never as failure.

🎓 Skills Your Child Will Develop

• 🏗️ Engineering Thinking — Testing structures, materials, and designs to see what works develops engineering intuition — the practical understanding of forces, materials, and design that underlies all physical construction and problem solving.
• 😌 Patience & Delayed Gratification — Experiments with delayed results — growing plants, watching crystals form, tracking weather — teach children to wait for outcomes rather than needing immediate feedback, a skill that predicts academic and life success.
• 🔄 Flexible Thinking — When an experiment produces an unexpected result, children practice adapting their thinking — a form of cognitive flexibility that makes them more resilient learners across all subjects.
• 🤔 Critical Thinking — Making a prediction, testing it, and explaining the result develops logical reasoning — the ability to move from observation to explanation that underlies all scientific, mathematical, and analytical disciplines.

Teach your preschooler about basic preschool physics topics by building easy and fun marble tracks using marbles and pipe cleaners. You'll be teaching your preschooler about gravity, motion and friction with this easy preschool physics activity.
