They develop spatial awareness, hand-eye coordination, and fine motor skills. They learn to recognize shapes, colours, and patterns, fostering early mathematical concepts.

Patterns introduce children to the concepts of sequence and order. Children can engage in pattern recognition by completing pattern cards or creating their patterns using objects like blocks, beads, or coloured tiles. Children can discuss their strategies, exchange ideas, and help each other solve puzzles, fostering social development and cooperative skills.

5. DIY Kaleidoscope

Preschoolers learn about concepts like light, reflection, symmetry, and geometry through the DIY kaleidoscope activity. This activity encourages children to use their fine motor skills, creativity, and imagination as they decorate the kaleidoscope and select objects for colourful displays.

To perform this STEM activity:

• Gather materials, including a cardboard tube, a plastic or glass cover, colourful beads or small objects, a mirror or reflective paper, and adhesive tape or glue.
• Begin by cutting the cardboard tube into a shorter length, approximately 4 to 6 inches.
• Attach the clear plastic or glass cover to one end of the tube. Attach a small mirror or piece of reflective paper inside the tube at a 45-degree angle using tape or glue. This will produce the kaleidoscope’s reflection effect.
• To complete the kaleidoscope, add colourful beads or small objects to the open end of the tube. Once the beads are in place, close the open end of the tube with the cover.
• When children look through the clear cover, they will see a mesmerizing display of colourful patterns created by the reflection and symmetry within the kaleidoscope.

6. Vegetable Garden

The vegetable garden provides opportunities to incorporate technology and engineering. This activity introduces preschoolers to scientific concepts such as photosynthesis, the role of insects in pollination, and the importance of environmental factors in plant health.
