In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.

Learners answer questions about the heat treatment of metals using a game show format. Immediate feedback is provided.

Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.

In this screencast, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.

Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.

Students view the formula for determining twist drill speeds in metal.

Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.

Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.

The tubehead is a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This learning object will provide students with practice identifying and labeling the dental x-ray tubehead.

In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

The learner will...be able to safely use grinding equipment in the welding and metal fabrication shop.

Learners examine the components of the x-ray tubehead, a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.

Step-by-step of setting the back gauge with an Adira Hydraulic Shear.

Learners read a description of the parts of an ironworker and identify them in an exercise.

Learners are asked to control the Adira press brake following the same steps they would if working on the actual machine.

Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.
