An adjustable scoop includes an indexed plunger rotatable to vary a scoop volume. The plunger includes exterior spiral grooves and the scoop includes angled interior tabs which fit into the the spiral grooves. The grooves include angularly spaced apart teeth which index with the interior tabs to retain the plunger at selected depths in the scoop. Index lines are angularly spaced apart on a base of the scoop and a pointer on the plunger is alignable with each of the index lines to set the plunger depth. The plunger is substantially hollow and includes a top surface providing a floor for the scoop, and an open bottom including a horizontal bar graspable to rotate the plunger. A level is slidably attached to a scoop handle and includes a leveling arc slidable across a scoop mouth to level material contained in the scoop.
