Four year olds are natural scientists. They ask “why” constantly, love to test what happens, and are fascinated by how things work. STEM for four year olds does not need special kits or equipment. With a few everyday materials and a curious attitude, your kitchen or backyard can become a science lab.
Why STEM matters in the early years
STEM stands for science, technology, engineering and maths. For young children, it is less about facts and more about thinking skills: observing, predicting, testing ideas, measuring and solving problems. These skills support learning across every area, from reading to friendships.
When children experiment, they also learn to be patient, try again when something does not work, and talk about what they noticed. That is a great foundation for school.
Simple STEM experiments with everyday materials
These activities use things most families already have. Always supervise closely, keep small items away from younger siblings, and let your child do as much of the hands-on work as possible.
- Sink or float: Fill a tub with water and gather items like a cork, spoon, leaf, toy block and apple. Ask your child to guess which will float before testing each one.
- Colour mixing: Add a few drops of food colouring to cups of water and let your child mix them with a dropper or spoon to discover new colours.
- Ramp races: Lean a chopping board on some books and roll different objects down. Which goes fastest? What happens if you make the ramp steeper?
- Ice melt: Freeze small toys in ice and let your child explore ways to free them using warm water, salt or sunshine.
- Build a bridge: Use paper, blocks or cardboard to build a bridge between two books, then test how many pegs or coins it can hold.
- Shadow play: On a sunny day, trace your child’s shadow with chalk in the morning and again in the afternoon. Talk about why it changed.
Measuring and maths in everyday play
Maths is everywhere in a child’s day. Invite your child to measure things using non-standard units, like how many hands tall the table is or how many steps it takes to cross the yard. Compare heights on a wall chart, sort the washing by colour, or count the plates as you set the table.
Cooking together is a lovely way to explore maths and science at once. Measuring cups, stirring, and watching ingredients change as they bake give children plenty to talk about.
How to encourage curious thinking
The way you talk with your child during experiments matters more than getting the “right” answer. Try asking open questions such as “What do you think will happen?”, “Why do you think that happened?” and “What could we try next?”
It is fine to say, “I’m not sure, let’s find out together.” Celebrate mistakes as part of learning, and let your child repeat an experiment as many times as they like. Repetition is how young children test and confirm their ideas.
If you are using screens for learning, keep it balanced. The Australian 24-Hour Movement Guidelines suggest no more than one hour of sedentary screen time a day for children aged three to five, so hands-on play is a great choice.
STEM learning at Nest
At Nest, curiosity is at the heart of our Reggio Emilia-inspired program. Children in our Kindergarten room explore, build, measure and investigate through play, supported by bachelor-qualified teachers. Our STEM and enrichment programs add even more opportunities to experiment and discover.
