为了讲述一般鱼类的成长厉程，我们这次用了小鲢鱼作为演示主体，4个阶段的标本包含了鱼卵、鱼苗、小鱼和成年的小鲢鱼。四个阶段皆选用了真实标本，务求能让小孩近距离面向真实的生物体。当亮起了配备的背光灯，相应的标本就会被燃亮，小孩能更清晰探究各物体的细节。一款少见的直接、真实和富教育性的自然科学教具。
A learning activity focuses on different developmental stages of a fish. The board containing real life specimens encapsulated in clear acrylic blocks which allow children to closely look into details. Life stages of most fishes starting with Eggs, Fry, Juvenille and ending with Adult Fishes can be seen and discussed with the added benefit of switches to light up each one in turn. Once lit-up, the specimens reveal all of their hidden secrets and children will be drawn in to examine them in greater detail. As well as the visual brilliance of these boards, children will also benefit from the rich words and language that surrounds these wonderous timelines. Batteries NOT included.
