The learner reviews steps in analyzing a process and applies them to a situation in his/her own work or personal life.

In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.

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.

In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

In this animated activity, learners observe impression procedures.

Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.

In this learning activity you'll observe how computers operate in a client-server network operating system and consider the advantages and disadvantages of such a system.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.

Learners observe the four functions of oil in a hydraulic system.

Observe disorganization in an office setting and choose solutions to the problems as if playing the board game "Clue."

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

Learners observe animations showing how data is converted between serial and parallel flow.

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.

Learners observe the animated operation of an astable mulivibrator using a 555 IC (integrated circuit) chip and external components.

In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.

Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.

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.

In this animated activity, learners observe how a viscometer operates.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
