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 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.

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

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 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 observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.

In this scenario, learners put themselves in the place of a safety director at a local company. They watch video of an injury-causing incident and propose changes to company policies and procedures to try to maintain a safe environment.

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

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

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

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

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 explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.

In this animated object, learners examine how changes in pH affect the salt bonds in strands of hair.

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.

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