STEM Education in Early Years: Science, Maths and Play

What STEM means for young children

In the early years, STEM is less a timetable of lessons and more a way of thinking. Children observe, wonder, predict, try something out and see what happens. They compare, count, measure, build and fix. These are the same habits of mind that scientists and engineers use, practised through play with water, sand, blocks, plants, ramps and everyday objects.

The four areas rarely appear separately. A child building a ramp for toy cars is testing how slopes affect speed (science), designing and adjusting a structure (engineering), using tools such as blocks and tape (technology) and comparing which car went further (maths). Good early STEM weaves these together naturally.

Why early STEM matters

Research on early learning suggests that children's early experiences with number, shape and pattern are linked with later learning, and that curiosity and persistence are important foundations for school. Early STEM experiences help build both.

• Curiosity and questioning: children learn that asking questions and finding out is enjoyable.
• Problem-solving and persistence: when a tower falls or a boat sinks, children try again with a new idea.
• Language: STEM play is full of words such as heavier, faster, float, melt, taller, more and fewer.
• Early maths: counting, comparing, measuring and recognising shapes happen constantly in hands-on play.
• Confidence: children come to see themselves as people who can work things out.

Just as important, early positive experiences can shape how children feel about science and maths later on. A child who has enjoyed mixing colours, growing seeds and building bridges is more likely to approach these subjects with interest rather than anxiety.

Early science and maths through play

Engineering play for kids

Engineering for young children means designing, building and improving things. Blocks, construction sets, cardboard boxes, tubes, tape and recycled materials are all excellent engineering materials. The important part is the process: having an idea, trying it, seeing what goes wrong and changing the design.

• Build a bridge from blocks or card that can hold a toy car.
• Make a ramp and test which objects roll fastest or furthest.
• Construct a den from blankets, chairs and pegs.
• Design a boat from foil or recycled containers and see how many pebbles it can carry before it sinks.
• Create a marble run using cardboard tubes taped to a wall or box.

Technology without screens

For young children, technology does not have to mean tablets. In early years STEM, technology includes any tool that helps us do a job: magnifying glasses, scales, measuring jugs, torches, scissors, pulleys, magnets and timers. Learning how to use simple tools safely and choosing the right one for a task are valuable skills.

Health organisations generally advise limiting screen time for young children and prioritising active, hands-on play and conversation. Where screens are used, sharing the experience and talking about it is more valuable than solo viewing.

STEM activities for young children at home

You do not need special kits to do STEM with your child. Kitchen cupboards, the garden and the recycling box offer plenty of materials.

1. 1Sink or float: fill a bowl with water, gather small objects and predict which will sink and which will float before testing each one.
2. 2Ice rescue: freeze small toys in ice and let your child experiment with warm water, salt and spoons to free them.
3. 3Colour mixing: give your child two primary colours of paint or coloured water and see which new colours appear.
4. 4Seed growing: plant beans in a clear cup with damp paper so your child can watch the roots and shoots grow.
5. 5Shadow play: use a torch in a dark room to make shadows bigger and smaller.
6. 6Measuring hunt: use a piece of string or your child's feet to measure furniture, then compare which is longest.
7. 7Pattern walk: look for patterns on a walk, such as stripes, spots, repeating tiles or leaves.

Many of these activities overlap with creative play. Mixing colours or making collages from natural materials, for example, is both art and science.

How STEM play changes with age

Toddlers explore mainly through their senses and simple cause and effect: filling and emptying containers, pushing buttons, rolling balls and stacking blocks. Between three and four, children begin to compare, sort and ask why, and enjoy simple predictions. By five and six, many can plan a design, test several ideas, record results with drawings or tally marks and explain what they found. Following your child's stage and interests keeps STEM play enjoyable rather than frustrating.

How adults can support STEM learning

The most important STEM resource is an interested adult. You do not need to know all the answers; in fact, saying "I'm not sure, let's find out" models exactly the curiosity you want to encourage.

• Ask open questions: "Why do you think that happened?" "How could we find out?"
• Encourage predictions before testing ideas, then talk about what actually happened.
• Use rich vocabulary such as dissolve, balance, heavier, transparent and pattern.
• Give children time to experiment, even if it is messy or does not work first time.
• Praise effort and thinking rather than just correct answers.

How STEM fits different preschool approaches

Many early childhood approaches include STEM-style learning, even if they do not use the term. Montessori classrooms use specially designed maths and sensorial materials. Reggio Emilia settings often explore scientific questions through long projects. Play-based preschools build STEM into block play, sand and water, cooking and outdoor exploration. You can read more in our guides to the Reggio Emilia approach and Montessori and play-based preschool.

Questions to ask a preschool about STEM

1. 1How do children explore science, maths and building during a typical day?
2. 2What materials are available for construction, measuring and experimenting?
3. 3How much time do children spend outdoors exploring nature?
4. 4How do teachers extend children's questions and interests?
5. 5How is screen use handled in the classroom?

At Altın Anahtar in Alsancak, we follow a play-based, child-centred approach for children aged 12 months to 6 years, where exploration, building and hands-on discovery are part of everyday play. To see our classrooms and garden, you can arrange a visit by appointment.
