In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.
In this interactive object, learners review the case of a patient with meningococcal meningitis.
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.
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 activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.
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 activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
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.
Learners read a brief introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis are shown.
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.
