This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
In this interactive object, learners use their knowledge of postpartum theory and the nursing process to complete a plan of care. The student's plan may be e-mailed to the instructor.
Students read about the different kinds of economic interest groups including business and trade associations, labor unions, agricultural organizations, and professional associations.
In this animated learning object, students are introduced to standard procedures, pilot actions, and pilot callouts for C-172 critical phases of flight.
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.
Students locate the seven countries in the Sahel region, which is between the Sahara and the coastal rain forests. They identify the famous city of Timbuktu in a map exercise.
