The screen displays a collection of different items, including fruits, stones, and leaves, placed on a surface. the objective is to observe the behavior of these substances when placed in water. fruits the fruits, such as apples or oranges, are depicted and shown to sink when placed in water. they submerge beneath the water's surface due to their higher density. stones various stones are also included in the visual prompt. when dropped into water, they sink to the bottom because they are denser than water. leaves several leaves are shown floating on the water's surface. they remain buoyant and do not sink due to their lower density compared to water. the leaves may move or "swim" on the water's surface, driven by gentle currents or wind.
