In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.

Learners explore actions that can be taken to achieve a buy-in from employees when changes are to be made in the workplace. Students then rank the steps in the order that they should be taken.

Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

In this animated object, learners read about the uses of nanotechnology. The sciences, engineering, electronics, and other disciplines converge in nanotechnology. Examples are given for applications in manufacturing, biomedicine, and environmental science. Concerns about possible environmental effects are discussed.

In this video, you’ll learn how to make changes to an engine lathe.

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

In this learning activity you'll relate statistics on aging in America to the functions and dysfunctions created by these demographic changes.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.

In this learning object, learners will follow the illness of an 83-year-old woman, noting changes in her condition and ordering the appropriate medical imaging studies needed to inform her physicians about both her progress and her treatment options.

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment completes the activity.

In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.

In this animated activity, learners examine how to change the gain of an optical sensor to overcome environmental conditions and distance.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners consider the changes inside a series motor that could cause it to break apart if the load was disconnected. A quiz completes the activity.
