This NDT Resource Center provides educational materials intended primarily for college students. The materials are intended to to aid in conceptual learning, to re-enforce materials provided at the student's school, and to serve as reference materials and working tools. Resource topics include...

This five-page instructor guide from Edmonds Community College provides a laboratory activity introducing students to the properties of metals using a paper clip. In this activity, a paper clip will fail after being bent multiple times, demonstrating the concept of fatigue. Students will compare and...

This six-page instructor guide from Edmonds Community College outlines a one-session laboratory activity demonstrating the effects of phase changes in metals, with a focus on high carbon steels and nickel titanium (nitinol). After completing this activity, students will be able to discuss the...

This four-page instructor guide from Edmonds Community College provides a laboratory activity demonstrating plastic deformation to students. Students observe plastic deformation in polyethylene, apply physical stress to a plastic sheet, and observe the "necking" effect this stress causes. This...

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan for students learning about polymers. The class will observe the physical properties of various plastics for rigidity, color, density and texture. The objective of the experiment is "to test and compare the...

This nine-page instructor guide outlines a laboratory activity testing the strength of fibers and fabrics. Students observe the properties of different fibers and fabrics and the differences between natural and synthetic fibers. This activity demonstrates why fibers may be chosen for different...

This learning activity shows how "differences in composition can drastically affect the properties of balls that look identical." Balls that appear the same but are composed of different materials will be bounced. Since they are made of different materials, students will observe a difference in the...

This six-page instructor guide from Edmonds Community College provides a lesson plan introducing students to ISO 14001, an international standard for environmental management systems. Through a CAD (computer-aided design) demonstration and discussion, students learn about the role product drawing...

This three-page activity guide from Edmonds Community College provides a laboratory activity teaching students about the reactivity of iron. Students observe the reactivity of iron in flame and water, and observe two types of iron oxidation. This activity demonstrates the effects different material...

This learning activity will provide an opportunity for students to develop their critical thinking and research skills in chemistry by asking them to investigate corrosion rates of metals and draw conclusions from their experiments. Students will measure corrosion rates in specific alloys and apply...
