Exploring STEM in Preschool: Hands-On Science and Math Activities

STEM (Science, Technology, Engineering, and Mathematics) education is more than just a buzzword; it's a vital component of early childhood development that fosters curiosity, critical thinking, and problem-solving skills. In preschool, hands-on STEM activities provide young children with exciting opportunities to explore the world around them, engage in scientific inquiry, and develop foundational math concepts. In this article, we'll delve into the wonders of STEM education in preschool and share some hands-on science and math activities that will inspire young learners.

  1. Colourful Sink or Float: Explore the concept of buoyancy with a sink or float experiment. Provide children with various objects of different shapes and sizes, such as blocks, toys, and fruits. Encourage them to predict whether each object will sink or float in a tub of water and observe the results. This activity introduces children to the basics of density and encourages scientific inquiry.

  2. Nature Scavenger Hunt: Take children on a nature scavenger hunt to explore the outdoors and discover the wonders of the natural world. Provide them with a list of items to find, such as leaves, rocks, flowers, and insects. Encourage children to use their observation skills to identify different plants and animals while fostering an appreciation for nature and the environment.

  3. Shape-Sorting Sensory Bin: Create a shape-sorting sensory bin filled with materials like rice, beans, or sand, and add various shapes cut out of coloured paper or foam. Encourage children to explore the sensory materials and sort the shapes by matching them to corresponding shapes on a sorting mat. This activity helps children develop spatial awareness and shape recognition skills while engaging their senses.

  4. Building with Blocks: Provide children with blocks of different sizes, shapes, and textures, and let their creativity soar as they build towers, castles, and structures. Encourage them to explore concepts like balance, stability, and symmetry while developing fine motor skills and spatial reasoning abilities. Building with blocks fosters creativity and problem-solving skills while laying the foundation for engineering principles.

  5. Counting with Counting Bears: Use counting bears or other small manipulatives to engage children in math activities. Encourage them to sort, stack, and count the bears while practising counting, sorting, and patterning skills. This hands-on activity makes math concepts tangible and helps children develop number sense and mathematical thinking.

  6. DIY Magnifying Glass Exploration: Create DIY magnifying glasses using plastic magnifying sheets or recycled materials like plastic bottles. Take children on a magnifying glass exploration adventure, encouraging them to observe and examine objects up close. This activity promotes scientific observation skills and introduces children to the concept of magnification.


Hands-on STEM activities play a crucial role in preschool education, providing young children with opportunities to explore, investigate, and discover the world around them. By engaging in hands-on science and math activities, preschoolers develop critical thinking skills, problem-solving abilities, and a lifelong love for learning. Let's inspire young learners to explore the wonders of STEM and lay the foundation for future success in science, technology, engineering, and mathematics.
