DTIC C_') EL-ECTIL L .,AU8 0 5 1982 MATERIALS LABORATORY Properties of materials We shall concern ourselves with three types of issues: (a) Mechanical properties of materials (strength, toughness, hardness, ductility, elasticity, fatigue and creep). The cohesion is a property of a solid body by virtue of which they resist from being broken into a fragment. deformed, and, when the load is further increased, the material will break. Properties and Changes of Materials has been split into two lists , which look at properties and changes of materials and changes of state.This list consists of lesson plans and activities to support the teaching of properties and changes of materials in Year Five.
