Observe & Predict
Children use simple scientific thinking: “What do I notice?” and “What do I think will happen?”
WonderLab Minis • Ages 4–6
Play-based STEM for preschoolers.
A playful, hands-on STEM programme designed for kindergartens and preschool afternoon activities. Children explore science, engineering, maths, nature and early coding through short missions, stories and safe experiments.
Kindergarten-friendly format
Age group4–6 years old
Duration40–45 minutes
Group size8–12 children recommended
Pilot4-week pilot available
✨
No prior STEM experience is needed. Activities are playful, simple and adapted to preschool children’s pace, confidence and curiosity.
What children learn
Curiosity, confidence and problem-solving.
WonderLab Minis is not a formal science lesson. It is a guided play experience where children observe, predict, build, test, improve, collaborate and explain what they discovered. The aim is to make STEM feel exciting, creative and accessible from an early age.
Build & Test
They create bridges, towers, boats, ramps and habitats, then test and improve their ideas.
Think in Steps
Screen-free coding games introduce direction, sequence, logic and debugging.
Work Together
Small-group challenges help children communicate, share materials and celebrate ideas.
October to June overview
A structured but flexible preschool STEM journey.
The full detailed lesson plan can be shared with schools as a proposal. The website shows the monthly themes and example activities, without overwhelming parents or school owners.
Autumn observations, sorting, patterns and first experiments.
Towers, bridges, strong shapes and rescue missions.
Melting ice, shadows, ramps and Christmas coding games.
Fizzy Moon Rocks, rockets, planets and crater experiments.
Colour mixing, magic milk, sink or float and bubble reactions.
Seeds, plants, mini greenhouse and ocean clean-up challenges.
Bug hotels, butterfly symmetry, animal tracks and nest-building.
Arrow paths, human robot games, mazes and robot missions.
Boat challenges, playground design, STEM stations and parent showcase.

Sample activities
A few examples of what children may experience.
Science
Fizzy Moon Rocks
Children become space scientists and observe a safe fizzing reaction using pipettes.
Engineering
Bridge Builders
Children build and test bridges to help a toy animal cross a river.
Coding
Coding Without Screens
Children use arrows and movement games to learn sequence and direction.
Discovery
Magnet Treasure Hunt
Children investigate which objects are magnetic and sort their discoveries.
Nature
Mini Greenhouse
Children plant seeds and observe what plants need to grow.
Invent
Little Inventors
Children design their own playful solution, test it and share what they created.
Safety and supervision
Designed for preschool settings.
Activities use simple, age-appropriate materials, small quantities, clear instructions and adult supervision. A teacher or assistant should be present during sessions, especially for experiments and group activities.
Start small
A 4-week pilot is the best first step.
A pilot allows the school to test the programme with children, parents and teachers before committing to the full October–June journey.
