What your Preschooler will Learn from this Preschool Plant Activity

How water moves up plants such as flowers

How colors mix to create new colors

What you Need for this Preschool Plant Activity

A dozen white daisies or chrysanthemums

A few cheap glass vases or cups

Food coloring (caution: food coloring stains easily)

Water

Scissors

Ribbon

What To Do

Step one: Add water to your vases.

Step two: Add a few drops of food coloring to your vases, whatever colors your preschooler wants. You may want only two different colors for your Valentine's bouquet or six different colors. You will need separate vases or cups for each color choice. Have fun with this step—let your preschooler mix colors and learn how different colors are created.

Step three: Cut the bottoms off your flowers and quickly put them into your vases or cups.

Step four: Wait a few days. Over time, the colored water will move up the plant, coloring the petals of the flowers.

Step five: Take the flowers and recombine them into one big bouquet. Tie the flowers together with your ribbon and give your Valentine's bouquet as a gift or use as a decoration.

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

• Science supplies don't need to be purchased. Vinegar, baking soda, cornstarch, salt, food coloring, and dish soap cover most preschool science experiments adequately.

• Visit science museums, planetariums, and nature centers regularly. Real encounters with scientific environments are more motivating than any experiment at home.

• Give children real tools: a real magnifying glass, real measuring cups, a real thermometer. Toy versions deliver less sensory and intellectual feedback than actual instruments.

• Integrate science into daily routines: cooking (chemistry), gardening (biology), building (physics), weather watching (meteorology). A science-rich home requires no special equipment.

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

• 😌 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.
• 📝 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.
• 🤔 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.

You and your preschooler can create a personalized valentine's bouquet for a loved one, or simply for your dining room table. Not only will your preschooler be creating a great gift, but with this preschool plant activity, your preschooler will be learning how water moves up a plant. They'll be learning the importance of water for plants with this preschool plant experiment.

Questions to Ask Your Child

Use these open-ended prompts to extend the learning during or after the activity:

• "What do you think will happen before we try it?"
• "Was your prediction right, or did something surprise you?"
• "Why do you think that happened?"
• "What would change if we tried it with something different?"
• "Can you think of a place in real life where you've seen this before?"
• "What question does this make you want to answer next?"

There are no right or wrong answers to any of these questions. The goal is to keep the conversation going, model curious thinking, and give your child practice putting their experience into words.
