How Exciting—Eggs Can Sink, Float in the Middle, and Rise to the Surface!
On Monday and Tuesday, 3–4 November 2025, the TK B pupils of Al Siddiq International took part in an exciting activity in their science class: an experiment investigating how eggs can sink, float in the middle, or rise to the surface. This activity was specially designed to introduce simple science concepts through hands-on experiences that are enjoyable and easy for young children to understand. The experiment was guided directly by the class teachers. The activity began with an introduction, during which the teacher greeted the children and explained that they would be conducting a fun experiment using water, salt, and eggs. The children looked enthusiastic and curious, as this was a brand-new experience for them. Step by step, the teacher demonstrated the experiment process. Three glasses were prepared, each filled with water and a different amount of salt: one with a small amount of salt, one with a moderate amount, and another with a large amount. After that, an egg was placed into each glass one by one. The results amazed the children. The egg in the glass with a small amount of salt sank to the bottom. The egg in the glass with a moderate amount of salt floated in the middle of the water, while the egg in the glass with a high amount of salt rose to the surface. This became an exciting moment that sparked the children’s curiosity about how water and salt can affect objects placed in it. The aim of this experiment was to introduce basic scientific concepts such as density and buoyancy in a concrete and enjoyable way. Through this activity, the children learned that objects may sink or float depending on the density of the liquid surrounding them. They also practised observing, comparing, and drawing simple conclusions from the results. This activity not only enriched the children’s scientific knowledge but also helped develop critical thinking, teamwork, and communication skills. Through active learning methods like this, the children do not simply learn theories—they directly experience how science works in the real world, in ways appropriate for their age and stage of development.By Inka Amalia, S.Pd
