The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."

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.

In this animated object, learners read an introduction to protein structure and function.

In this animated object, learners examine the major events that occur at the neuromuscular junction.

In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.

In an interactive exercise, learners identify the human body sites that harbor a normal resident flora and the sites that are sterile.

Explore what proteins are, their structure, and their functions.

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

Explore what passive transport diffusion is and how it moves water through a membrane.

In this learning activity you'll review the structure and function of the different tissues of the human body.

Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.

Learners examine a table containing the names of common cations and anions.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

Learners examine the structure and function of skin including the production of melanin.

In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions

In this animated object, learners examine the chemistry behind table salt.

The purpose of this learning object is to introduce the dental hygienist to the process of documenting a patient's dentition.

Learners examine how chemists use moles to "count" atoms by weight. Examples are given.

Learners review and reinforce their knowledge of brain anatomy and function in this learning activity.

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

The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.

In this screencast, learners examine the bones of the appendicular skeleton.

In this screencast, learners read about the parts of the eye.
