The Tasting Bottle set (A 121) is a sensorial material for the primary environment that isolates the gustatory sense by presenting children with small bottles containing solutions representing the four basic tastes: sweet, sour, salty, and bitter. Children sample and match or grade the bottles by taste, building sensory vocabulary and discrimination in an area that is often underdeveloped in traditional early childhood settings. This material pairs well with discussions of food preparation in practical life and extends the sensorial curriculum beyond the more commonly emphasized visual and tactile exercises.
