What your Preschooler will Learn from this Preschool Science Experiment:

Natural Techniques for dying Easter eggs

That vegetable products have natural dyes that can transfer to objects (such as eggs)

Basic experimentation.

What you'll Need to Create Red-Purple Eggs:

Eggs

Red onion skins

A large pot

Boiling water

What to do:

Step one: Boil your water in your large pot.

Step two: Have an adult the eggs to the water.

Step three: Add the red onion skins to the water. Some people have better results if they wrap the eggs in the red onion skins with a rubber band and then add the eggs to the boiling water.

Step four: Wait about fifteen minutes.

Step five: Check the color of your eggs. Add some time if needs be.

Do not add vinegar (unless you want to see what will happen) to your water if using red onion skins—it'll change the color of your dye.

What you'll Need to Create other Colors:

Eggs

A large pot

Boiling Water

White Vinegar

Natural dye products. Examples of popular ones include coffee grinds, cumin, boiled spinach leaves, boiled red cabbage leaves (this one's great!), purple grape juice.

What to do:

Step one: Boil your water in your large pot.

Step two: Add a teaspoon or two of vinegar to your boiling water before adding the eggs. This will help the dye stick to the eggs

Step three: Add your dye product.

Step four: Monitor the eggs. The color will be more intense the longer you boil the eggs.

Step five: Have your preschooler note in their scientific journal about the products you used what the result was. Keep this journal so you can refer back next year.

Tips for this Preschool Science Experiment:

Be cautious when handling your eggs. The vinegar weakens the shells and they'll be easier to crack.

Be cautious about eating your eggs after dying them. While they won't make you sick, the may taste bad depending on what you used to dye them.

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

• 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.

• Accept wrong predictions gracefully — "Interesting! The result was different from what we predicted. Why do you think that happened?" Models scientific resilience.

• Connect science observations to real-world applications: "This is why bridges are built this way" or "This is how your body does that." Application makes science relevant.

Frequently Asked Questions

How do I keep science learning going between experiments?

Science is a mindset, not a schedule. Keep a magnifying glass accessible for impromptu investigation. Ask "why do you think...?" during daily life. Notice scientific phenomena out loud: "Look at how steam rises from the soup — where does it go?" Maintain a simple nature observation area (a window bird feeder, a terrarium, a weather chart). The child who develops the habit of curiosity about the physical world is doing science continuously, not just during scheduled experiments.

🎓 Skills Your Child Will Develop

• 💬 Science Vocabulary — Science introduces children to precise vocabulary — observe, predict, hypothesis, dissolve, absorb, transparent — that dramatically expands language range and supports the academic vocabulary children need in school.
• 🏗️ 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.
• 📝 Recording & Documentation — Drawing what they observe, recording measurements, and noting results gives children their first experience of scientific documentation — and connects science to literacy and numeracy in an authentic context.
• 🔍 Observation Skills — Paying close attention to what happens during an experiment — noting colors, textures, movements, and changes — builds the observational precision that all scientific and analytical work requires.

There are a lot of great ways to dye eggs for Easter and no they don't all have to involve food coloring or those little tablets that dissolve in hot water. There are also natural dying techniques you can use to dye eggs for Easter. Do this fun preschool Easter science experiment with your preschooler to discover ways to create your own dye.

This is a great preschool science experiment for basic experimentation. What happens when you add a certain product to boiling water? Will it create a dye strong enough to dye eggs? There's no limit with what you try. Have fun!
