In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

Learners will understand the technical terms used in the context of the SDS to help them interpret its information.

In this learning activity you'll review the hazardous materials safety document which display an example of a SDS or MSDS (Material Safety Data Sheet).

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 read about the types of lines found on blueprints. A quiz completes the activity.

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

In this activity we’ll explain what a title block is and how to read the information it holds.

Learners examine how metal detectors function. This object includes animation and sound.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Learners read how nanotechnology is creating new jobs in emerging industries while making others obsolete. This colorful and animated activity also looks at the types of products being created through the use of technology and how educational institutions have responded.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

In this interactive lesson, learners read and hear instructions for sending an e-mail. Steps are given for composing an e-mail message and for sending it. Students have an opportunity to write their own messages. A quiz follows the instruction.

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

In this learning activity you'll discover how to evaluate a problem statement using both the MEA and the IP Techniques.

In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.

The learner examines what it means to listen respectively and how to become a better listener.
