The mechanic contents of materials and structure in junior high school technology education was extracted in terms of the strength of materials and the structural mechanics. The extracted contents were analyzed considering the force action in the material and structure. The analyzed results were classified on the basis of morphologic models in strength of materials and structural mechanics. The classified morphologic models were shown in following nine models: Bending strength in simply supported beam, bending deformation in cantilever beam, shearing force, moment of inertia of area, rigid frame structure, planar structure, rigid joint, hinged joint and truss structure. The results of the questionnaire showed that the junior high school students were hard to understand about the condition of force action and the direction of resistant force in material.
