Science and Literacy in Preschool: Planting the Seeds of Curiosity and Communication

Dr. Deb Zupito

Preschoolers are natural scientists. They ask big questions:“What happens when it rains?”“Why do bugs move like that?”“Why is the moon following me?”

Planting The Seeds

These questions aren't just cute, they are the foundation of scientific inquiry. And every time children ask, describe, predict, or explain, they are also using literacy skills. Science fuels curiosity and discovery; literacy gives kids the words and tools to think, talk, and reflect on what they learn.

When we combine science and literacy in early childhood, we build more than knowledge, we grow thinkers, talkers, and problem-solvers.

Why Mix Science and Literacy in Preschool?

Combining these two areas of learning:

• Builds vocabulary and language comprehension

• Encourages curiosity and critical thinking

• Supports storytelling and communication

• Helps children connect ideas to the real world

Children who explore science concepts with books and conversation develop stronger language skills. Research shows that integrating science and literacy improves cognitive development, especially when children talk through what they observe.

Planning for Science + Literacy

Start with the topics kids are naturally curious about: weather, plants, bugs, magnets, shadows, water. Use these interests to guide:

• Read-alouds: Fiction (Rosie Revere, Engineer) and nonfiction (National Geographic Little Kids)

• Hands-on experiences: Planting seeds, melting ice, testing what sinks or floats

• Daily routines: Washing hands becomes a germ science moment; snack time becomes a mini anatomy lesson

Ask open-ended questions:“What do you notice?”“What might happen next?”“Why do you think that happened?” Science does not need to be complicated. A puddle and a question can launch an entire learning moment.

Tools That Support Both Worlds

Science Tools:

• Magnifying glasses, mirrors, droppers, scales, sensory bins

• Nature collections: leaves, rocks, feathers

Literacy Tools:

• Science journals (even scribbles count)

• Picture word walls (observe, test, change, describe)

• Books that connect story and science

Optional Tech:

• Digital microscopes

• Child-friendly documentation apps (like Seesaw)

Let’s Talk: Why Conversation Matters

Language is how young scientists express what they think, feel, and see.

• Model curiosity: “I wonder why that bubble popped so fast?”

• Use rich vocabulary: Introduce words like predict, investigate, observe

• Encourage peer talk: “Can you tell your friend what you saw?”

Talking about science strengthens both understanding and communication. When children explain their thinking, they’re learning how to process and share ideas.

Tips for Teachers and Parents

• Let go of needing the “right” answer, value the process

• Follow the child’s lead, the best science moments are spontaneous

• Revisit science experiences through drawings, retelling, and books

• Celebrate discovery, even if it’s messy or doesn’t go as planned

• Keep it playful, joy fuels learning

The Takeaway

Preschoolers are already scientists and storytellers. When we connect science and literacy, we don’t just teach facts, we empower children to explore, describe, and understand the world around them. By nurturing curiosity, giving children the words to express their wonder, and creating space to explore freely, we’re building thinkers for life.
