In this screencast we are introduced to the lab equipment used to contain and dispense chemicals.

The purpose of this learning object is to introduce the learner to the different processes of science.

The learner follows a step-by-step procedure for testing a computer ground circuit.

In this learning activity you'll define what a variable is, how they're used in the C# programming language, and how the computer works with variables under the hood.

In this learning activity you'll review what a variable is, how to use variables in JavaScript, and how the computer works with variables.

In this interactive object, learners examine the structural-functional, social-conflict, and symbolic interaction analyses of science and technology. A mind map and quiz questions are included.

In this interactive exercise, learners label the components of a workstation, a Windows desktop, and an application window.

In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

In this learning activity you'll discover the functional differences between value and reference types within the .Net framework.

In this learning activity you'll review how a local area network computer uses a subnet mask to determine if its message is intended for a computer on the same network or on a remote network.

In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.

In this learning activity you'll explore the food pyramid and the recommended services.

In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

In this animated learning object, students examine the life cycles of a virus.

In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.

Students practice identifying common elements from the periodic table by name or symbol.

By the end of this module, you'll be able to:

- Identify actions that can reduce biosecurity risk

- Develop a biosecurity action plan for a farm

- Select the most cost effective strategies

Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.

Discover the fascinating intersection of veterinary science and human medicine in this module. "Can Animal Studies Predict Human Results?" Dive into groundbreaking research and ethical debates as we explore how animal testing influences the future of medical breakthroughs by unraveling the complexities of animal and human testing.

In this animated object, learners read about the uses of nanotechnology. The sciences, engineering, electronics, and other disciplines converge in nanotechnology. Examples are given for applications in manufacturing, biomedicine, and environmental science. Concerns about possible environmental effects are discussed.
