In this learning activity you'll walk through a direct variation problem.

Visualizes direction and quantity of glass particles as the glass is impacted by a force.

Visualizes direction and amount of glass particles travel when impacted by a force.

In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

Learners practice revising poorly written directions by applying criteria for giving directions.

Learners write directions to gain experience asking questions from the point of view of the person who must follow the directions.

Learners evaluate how well a set of directions instructs a person about to perform a task for the first time. The focus is on avoiding assumptions.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Learners read and listen to phrases in Mandarin Chinese that would be part of directions to common locations. Additional vocabulary words related to forms of transportation are also presented.

In this animated object, learners evaluate oral directions and compose questions to clarify ambiguities. This activity has audio.

In this animated and interactive object, learners follow oral directions in the workplace. They complete their task within a time limit. This object has audio content.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.

In this animated activity, learners read an explanation of the four different modalities (currents) used in electrotherapy.

The student watches a car move through a city and writes directions based on the car's route.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

In this interaction the student is presented with 10 questions on indirect measuring devices and their uses.

In this learning object you'll review direct, inverse, joint, quadratic, and combined variations.

In this learning activity you'll review a visual overview of indirect measurement.
