In this learning activity you'll explore why the FTP protocol is often used to transfer data across the network and more importantly, why it should not be.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

This primer introduces the student to the correct method of using the internal memory of a TI-86 calculator.

This document provides a list of shop safety rules.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

In this interactive and animated object, learners examine open and closed head injuries and the common causes and symptoms related to them.

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.

This primer introduces the student to the correct method of using the arctangent function on a TI-86 calculator.

Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.

Learners examine how visual controls help to manage the workplace. Photos of visual controls are provided.

Students read about fresh herb garnishes and match the garnishes to appropriate foods.

Students examine examples for calculation yield, throughput yield, rolled throughput yield, and payback, each of which is used to analyze process performance in a Six Sigma project.

In this video, we’ll identify the parts that make up the Bridgeport and learn how it works.

In this learning activity you'll test your skill at reading indicators.

In this screencast, learners examine the action of insulin and other antidiabetic medications.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.
