In this screencast of an old Flash learning object, learners follow along as we sort parasites into divisions and helminth divisions. We'll also identify affected body systems.

Learners examine the structure and function of skin including the production of melanin.

In this animated and interactive object, learners identify the valves and chambers of the heart.

This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.

Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.

In this animated object, learners examine automated manufacturing systems classified as motion control, batch process control, and continuous process control.

In this screencast, learners review the parts of the gastrointestinal system and then check their knowledge in a matching exercise.

In this interactive object, learners assign water supply fixture units to a water distribution system using Section 82.40 of the Wisconsin Plumbing Code.

The learner assigns water supply fixture units and pipe sizes to a water distribution system using the Wisconsin Plumbing Code and a uniform pressure loss worksheet.

In this learning object, students will learn about the attachment

process of specific sugars to red cell membranes and how the sugars

determine ABO antigenic activity.

The learner will use the ANSI Insert Identification System to identify and select carbide tools.

In a series of practice problems, learners use the substitution method to solve systems of linear equations, also called "simultaneous linear equations."

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

This Learning Object is designed to identify the various components of a vehicle's seatbelt system, and to show evidence of seatbelt use following a collision.

In this learning activity you'll practice converting from one metric unit to another.

Learners play a vascular system "game" to identify the arteries, capillaries, and veins that make up the renal blood supply pathway. A score is given at the end of the activity.

Learners read a detailed description of the VAT-40 tester and practice using it in an interactive exercise.

In this learning activity you'll place given vectors in correct positions on the Cartesian coordinate system.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."
