These science activities for elementary students focus on the external structures and functions of the human eye with hands-on object box activities based on the Montessori theory (1966) of concrete learning through manipulation of objects and focus of attention through touch. Object boxes are sets of items and corresponding cards housed in a box. Two types of object boxes are highlighted: (a) form and function analogy object boxes that describe the structures and functions of external parts of the human eye along with analogous manufactured items exhibiting the same forms and functions and (b) words with multiple meanings object boxes that present objects and two different meanings of eye-related words. These activities use analogy to help learners construct connections between previous and new learning along with developing vocabulary for better thinking and communication.
