In this video, you'll review how every protein molecule of an organism is synthesized.

In this learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.

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

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

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

In this learning activity you'll explore public key encryption and conclude with a short quiz.

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

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

In this learning activity you'll learn what Zip files are, their origins, and how to work with them in Windows.

Learners follow the path of a protein food from consumption through digestion to absorption into the bloodstream.

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.

Learners view animations showing how hubs and switches work in local area network configurations.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

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

The learner will understand how to properly use a fillet gage to measure weld size.

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