This lesson, presented by the National Nanotechnology Coordinated Infrastructure, introduces the concept of water purity. In this activity, students will test a sample of water collected from a local water supply and test its purity and evaluate its safety for consumption by looking for pollutants....

This 56-page textbook was created for the WELD 203: Layout and Fabrication Techniques course taught at Lake Washington Institute of Technology. This textbook covers a variety of topics and includes a number of related lab assignments. Completing these assignments will demonstrate all of the skills...

This lab, presented by the National Nanotechnology Coordinated Infrastructure, will "help students understand how chemical reactions are used to create the specific shapes on surfaces of crystalline materials, which make up functional components within electronics." The wet etching process is used...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity as a vehicle to examine the I-V characteristics of a diode versus a resistor. The exercise will measure the voltage drop across both a diode and a resistor as voltage is varied. Students will then discover the...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity as an introduction to the physical properties of matter. The objective of this laboratory is to identify different classes of matter based on their physical properties, specifically the ingredients of concrete. The...

The Materials Science and Technology Teacher's Workshop (MAST) provides this experiment on the reactivity of metals. The module will help illustrate the chemistry of metals and how metals are used together to prevent corrosion. The lesson includes a step by step explanation of the laboratory...

This 99-page textbook, created by Lake Washington Institute of Technology, provides a comprehensive overview of wire feed welding. The textbook focuses on the "principles, procedures, and operation of equipment to properly and safely use the Gas Metal Arc Welding (GMAW), Flux Core Arc Welding...

This collection of resources, from the Cybersecurity Education for Advanced Manufacturing Organizations project, is a part of the Wireshark Scenario. This scenario is a training module that introduces Wireshark, a free program used to monitor and inspect network traffic. The module teaches the...

This activity will demonstrate the process of work hardening and annealing of a copper. Students will get the opportunity to see the hardening of metal by deformation, experience the process of work hardening, explain the effects of work hardening in metals and experience property changes affected...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity for classes learning about semiconductors and LEDs (light-emitting diodes). The class will observe visible LEDs in simple electrical circuits, relate the composition of semiconductor materials with their behavior...
