Dibber International Preschools says early science and maths learning can begin with ordinary materials already found in South African homes and classrooms.
Simple changes to the spaces where young children play can encourage early scientific thinking without expensive equipment or formal lessons, according to Dibber International Preschools South Africa. By giving preschoolers access to open-ended materials such as blocks, containers, water, stones, and bottle caps, and allowing them to predict, test, and try again, parents and educators can turn ordinary play into meaningful STEM exploration during a vital period of early development.
STEM, which brings together science, technology, engineering and mathematics, can sound far removed from preschool life. For a young child, however, it is already happening when a tower collapses, and they rebuild it, when they sort objects by size or colour, or when they wonder why one object floats while another sinks.
“STEM in the early years begins with curiosity,” says Ursula Assis, Managing Director of Dibber International Preschools South Africa. “A preschooler asking, ‘What will happen if I do this?’ is already thinking like a scientist. The adult’s role is often to give that question somewhere to go rather than rushing in with the answer.”
The environment matters because young children learn through direct experience. A shelf containing loose, open-ended materials can give a child far more opportunity to experiment than an activity designed around a single correct result.
A container of water and a few household objects can become an investigation into sinking and floating. Blocks or empty boxes invite children to explore height, balance and stability. Buttons, seeds or bottle caps introduce sorting, counting and pattern recognition through play.
“What matters is that the child gets to predict, test, observe and change something,” says Assis. “If a tower falls, the learning is in wondering why and deciding what to do differently next time. That willingness to keep testing an idea is something children can carry into later learning.”
This approach is notably relevant in South Africa, where access to formal educational resources differs widely between communities. Meaningful STEM activities for preschoolers do not have to depend on specialised kits, screens or costly classroom equipment.
Many of the strongest opportunities begin with what is already available.
An adult can deepen the experience by asking a simple question. “Which one do you think will float?” or “What could make your tower stronger?” gives the child a reason to think without turning the activity into a lesson with a prescribed answer.
That distinction matters. Preschoolers are naturally curious, and their frequent questions are part of how they make sense of the world around them. Environments that leave room for experimentation help children build confidence in their own thinking.
The aim is also bigger than completing a particular STEM activity. It is about developing a habit of inquiry.
A child who becomes comfortable asking why something happened, trying another approach and noticing what changes is practising skills that will remain useful long after the blocks or water basin have been packed away.
At Dibber, this kind of exploration is built into early learning environments where children are encouraged to investigate, build, test ideas and follow their own questions.
“Children do not need adults to turn every moment into a formal lesson,” says Assis. “Sometimes the most valuable thing an adult can do is provide interesting materials, ask one thoughtful question and give the child enough time to work something out.”
For parents, that means early STEM learning can begin on a regular afternoon. A few objects, some space to experiment and a child asking “what happens if?” may be all that is needed.
