Children are naturally drawn to bright, vivid colours, which makes rainbow-themed science experiments instantly engaging and relatable. Because colours are part of their everyday world—seen in toys, clothes, art, and nature, rainbow experiments provide a familiar entry point into scientific exploration.

These activities spark curiosity and wonder by showing how ordinary materials can transform into extraordinary displays of color. Whether it’s watching water “walk” across paper towels, seeing milk swirl into rainbow patterns, or layering liquids into a colorful tower, children experience science as something magical yet understandable.

Children are natural scientists. They observe, question, and experiment every day—whether it’s watching ants march across the playground or noticing how shadows change with the sun. A thoughtfully designed science and nature area in an early childhood environment nurtures this curiosity, offering a space where exploration becomes intentional and learning is scaffolded. Such an area not only supports STEM skills but also fosters respect for the environment, cultural knowledge, and sustainable practices.

Here’s a themed EYLF-aligned guide to 30 preschool science experiments, complete with materials, instructions, science concepts, and EYLF learning outcomes. This is designed for educators who want to embed intentionality, inquiry, and curriculum links into hands-on science.

Here’s a roundup of 20 super simple science experiments for toddlers in early learning settings. These activities are sensory-rich, safe, and designed to spark curiosity while introducing foundational science concepts.

With National Science Week on from 9th to 17th August 2025, this is a great opportunity to introduce science to babies. For babies it’s less about formal experiments and more about sensory exploration, pattern recognition, and curiosity-driven play—all foundational to scientific thinking and nurturing their natural curiosity and helping them explore the world through sensory-rich, playful experiences.

Exploring science in early childhood is a fantastic way to nurture curiosity and a love for learning in young children. The following article provides information on Benefits Of Exploring Science In Early Childhood, How To Get Started, How To Create A Science Rich Environment, Incorporating Science into Daily Activities, How To Integrate Science With Other Subjects, Examples Of Themes To Explore Science, Linking To The EYLF and more. 

Dancing corn is a fun sceince experiment to do with toddlers and preschoolers. Watch corn dance with a little kitchen chemistry.

Elephant toothpaste erupts a foam that children can create in this experiment that resembles toothpaste being squeezed from a tube.

Make a hard egg bounce by adding it to a cup of vinegar. This is a great STEAM experiment to try with children - make different colour "egg balls" and watch how vinegar dissolves the hard shell to create a bouncy egg. 

National Science Week is Australia’s annual celebration of science and technology and it is held from 12 - 20 August 2023.
