Materials and Tools
Broad Concept: Appropriate materials, tools, and machines extend our ability to solve problems and invent.
|1.1 ||Identify materials used to accomplish a design task based on a specific property, i.e., weight, strength, hardness, and flexibility.|
|1.2 ||Identify and explain the appropriate materials and tools (e.g., hammer, screwdriver, pliers, tape measure, screws, nails, and other mechanical fasteners) to construct a given prototype safely.|
|1.3 ||Identify and explain the difference between simple and complex machines, e.g., hand can opener that includes multiple gears, wheel, wedge gear, and lever.|
