A group of children are in an indoor swimming pool, participating in a swimming lesson. Several children are in the water, with some wearing swim caps and goggles. One child in the foreground on the left side of the pool is wearing a pink swimsuit and swim cap, and is standing near the edge. In the middle of the pool, several children are swimming or being assisted by an instructor. Some are using kickboards or flotation devices. In the background, more children are visible swimming in different lanes. The pool is well-lit with overhead lights, and there are decorative flags hanging from the ceiling. Equipment, including red and black kickboards and pink fins, are placed on the edge of the pool in the foreground. The water is clear blue, and lane lines are visible on the bottom of the pool.
