Materials Matter
11 th Grade Engineering Module Overview
Topic: Materials
Grade Level: 11th
Course: Engineering - High School
Time Allotted for Module: 30 days
Prior Knowledge: Familiarity with computer spreadsheets and how to graph data.
Overview
This module will introduce students to the world of materials. The students will first encounter the basic
properties and characteristics of materials and how to categorize them, moving on to examine
mechanical, and thermal, properties, including how to measure these properties using different
methods. The students will then be introduced to metals, ceramics and polymers – the different types,
uses, their properties and characteristics, and how to measure them. Students will design their own
metallic Mars rover, learn how to write a technical brief, and use their knowledge to prepare a brief for
a NASA application.
Vocabulary
Ceramics: Ceramics are nonorganic, non-metallic solids prepared by the action of heat and subsequent
cooling. Ceramic materials may have a crystalline or partly crystalline structure, or may be
amorphous (e.g., a glass). Because most common ceramics are crystalline, the definition of
ceramic is often restricted to inorganic crystalline materials, as opposed to the non-crystalline
glasses.
Deformation, Elastic: Occurs when a material is strained (deformed) but returns to its original shape,
like a rubber band
Deformation, Plastic: Occurs when a material is strained (deformed) beyond its yield strength and
does not return to its original shape, like silly putty
Fatigue Strength: The maximum amount of stress a material can take one million times without
breaking
Flexure: A form of bending, flexure characterizes the behavior of a slender structural element
subjected to an external load applied perpendicularly to an longitudinal axis of the element.
Polymer: A polymer is a large molecule (macromolecule) composed of repeating structural units
typically connected by covalent chemical bonds.
Strain: The percent amount of elongation or compression of a material
Stress: The amount of force applied over the area of an object, computed by dividing force by area
Stress, Comprehensive: Stress that squeezes a material together

Tensile Stress: Stress that pulls a material apart
Tension: The magnitude of the pulling force exerted by a string, cable, chain, or similar object on
another object
Ultimate Tensile Strength: The maximum amount of tensile stress a material can take before
breaking
Yield Strength: The maximum amount of stress a material can take before it deforms plastically
(permanently)
