Students will learn how to document bloodstains using roadmapping equipment materials

The learner will understand the structural organization of the SDS and be able to find pertinent safety information using the SDS.

In this animated activity, learners practice listening and counting the apical pulse of adults, children, and infants.

Learners write an account of a workplace incident and evaluate statements for objectivity.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Learners read what the letters DMAIC stand for and then complete a matching activity.

This primer introduces the student to the proper method of complex number conversion on a TI-86 calculator.

Students read how to determine and calculate the dry density for a given sample of soil or aggregate based on the mass-volume relationship.

The student is shown and then identifies the parts of a hydraulic shear.

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).

This project gives a drawing with steps to complete the activity.

Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.

Students view the formulas to be used to convert a series impedance to a parallel impedance.

Students identify the various regions of the human body through drag-and-drop exercises.

Learners solve two sample problems for a numerical reasoning assessment.

Students view the operation of a process controls system and examine the components and their function to prepare to work with the actual system.

Learners read a brief description of Kaizen and how it helps to eliminate waste in a process.

Learners examine the benefits of using blogs in a school setting and then test their knowledge in two exercises.

In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.

In this interactive learning object, learners read how to compensate for a part not mounted perfectly parallel to the machine axis.

Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.

In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

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 screencast, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
