This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.
In this interactive object, learners examine the characteristics of osteoarthritis, rheumatoid arthritis, and osteoporosis. Students then describe the precautions to be aware of when working with clients who have arthritis and identify assistive devices that clients might use to prevent injuries at home.
Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.
Learners reflect on their own attitudes toward change and list them in the order they might experience them. In a separate exercise, they prioritize the actions a group might take when faced with change in the workplace.
Interpreting Engineering Drawings: Common Abbreviations
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a holder. A short quiz to test your ability to correctly read this information follows.
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
