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.

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.

Students identify the parts of a triple beam balance and practice measuring the mass of objects.

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

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

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

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.

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

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.

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

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

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

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.

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

- List four categories of disease agent sources

- Discover conditions when disease transmission is likely to occur

- Describe the means of disease transmission in a given situation

In this learning activity, you'll explore the basics of prototyping for user experience design.

In this module, you'll be able to :

- Identify five routes of infection

- Describe how diseases are transmitted in animals

In this video, learners view the parts of an animal cell and its organelles.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

Students use a map of Chicago to find their way to the Museum of Science and Industry. The activity offers practice in identifying directions on a map. A quiz completes the activity.
