In this animated object, students examine the role that the solubility of water plays in various biological functions.

In this interactive object, learners identify the parts of an animal cell and its organelles.

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

Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.

Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.

Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.

In this animated and interactive object, learners examine how blood flows through the heart and lungs. A brief quiz completes the activity.

Students identify the various regions of the human body through drag-and-drop exercises.

Students identify the various regions of the human body through video.

In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position. Check out our video on relative position: https://bit.ly/2kTXujp

The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.

This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.

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

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.

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

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

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

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

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

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 and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.

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.
