Colors, shapes, and sounds - what children aged 5 to 7 already know from their everyday lives, they learn to actively question and understand through a variety of experiments. Exploring corners and edges, crafting a spinning drum, creating exciting effects with mirrors, and discovering symmetry and asymmetry - this is how learning becomes fun. How do I recreate the picture using Tangram pieces? Can a cup cluck? Guided by the illustrated instructions, children delve into these and many other questions. Purposeful experimentation with pipettes and other tools develops fine motor skills and concentration, playfully preparing them for school with small tasks. The Kosmos Experiment Kit is a comprehensive set for preschoolers that even encourages adults to pay attention, listen, and join in the fun. Why wait for school to start? There’s already plenty for children to learn beforehand: colors, shapes, and sounds are part of their everyday lives - and now they connect experiences with knowledge: How do I create a rainbow in a test tube? What surprising effects can I achieve with mirrors? And how do I make sounds with the tone bars? The instructions guide through the multitude of experiments with illustrations and encourage participation and completion - thus, children are trained in their fine motor skills and concentration while being gently prepared for school. Whether with small instruments, Tangram, or sugar pictures - learning becomes a playful experience with the numerous materials. Adults are also invited to pay attention, listen, and guess along.
