Date: ________________ Unit 3 - Production Materials, Tools & Tool Safety Homework Standard 1: Materials, Tools & Machines
Appropriate materials, tools and machines enable us to solve problems, invent, and
construct
Strand 1.1: Given a design task, identify appropriate materials (e.g., wood, paper,
plastic, aggregates, ceramics, metals, solvents, adhesives) based on specific properties
and characteristics (e.g., strength, hardness and flexibility).
Strand 1.2: Identify and explain appropriate measuring tools, hand tools, and power
tools to hold, lift, carry, fasten, and separate, and explain their safe and proper use.
Strand 1.3: Identify and explain the safe an proper use of measuring tools, hand tools,
and machines (e.g., band saw, drill press, sander, hammer, screwdriver, pliers, tape
measure, screws, nails, and other mechanical fasteners) needed to construct a prototype
of an engineering design.
