<![CDATA[Science education for young children should provide opportunities for them to observe, experiment, and explore phenomena firsthand. The "dancing colors" experiment—conducted within the theme of water—serves as an alternative activity that offers a concrete learning experience through the shifting patterns of colors on the surface of milk. This study aims to describe the forms of active participation exhibited by young children during the "dancing colors" experiment at TK Muslimat NU 200 Kureksari, Sidoarjo. Employing a qualitative approach with a descriptive method, the study involved 26 children from "Group B" during a single session in May 2026. Data were collected through observation, documentation, and pedagogical reflection, then analyzed descriptively by categorizing the data, presenting findings, and drawing conclusions. The results indicate that the children’s active participation was evidenced by their focused attention on color changes, enthusiasm for the activity, eagerness to conduct the experiment, observation of color movement, spontaneous questioning, and engagement with peers. One notable response was a child’s question: "Why do the colors mix on their own without being touched?"—a remark that highlights the child's curiosity regarding the observed phenomenon. These findings suggest that the "dancing colors" experiment provides an opportunity for children to engage directly in science learning through concrete, exploratory experiences. However, as the study was conducted over a single session, the results are limited to a description of the observed participation and are not intended to demonstrate a quantitative increase in participation or establish a cause-and-effect relationship.]]>
