The Combined Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners combine Boyle's Law and Charles's Law to solve for the pressure, volume, and temperature of a gas sample under two sets of conditions.
In this animated activity, learners compare the van der Waals equation with the Ideal Gas Law.
Percent Composition of Compounds
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the method used to calculate the mass percent of an element in a compound. Three examples and one problem illustrate the method.
"I Want to Be Well" Case 1: Respiratory Pathogens
By Dawn Madl
In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.
Parasite Matching Exercises
By Elizabeth Yoon
Learners match the names of parasitic organisms to the diseases they cause and the modes of transmission.
Fungal Disease Matching Exercises
By Marise Hussey
Learners test their knowledge of fungal diseases by completing six exercises.
Protein Synthesis (Video)
By Becky Polk-Pohlman
In this video, you'll review how every protein molecule of an organism is synthesized.
Anatomical Terminology: Relative Position Video
Students identify the various regions of the human body through video.
The Cell: Passive Transport Osmosis (Video)
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
The Unipolar and Multipolar Neurons
By Barbara Liang
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
By Carol Parent-Paulson
This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.
The Four Types of Chemical Reactions
In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
The Corticospinal Tracts
In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.
Antigen Presentation: T and B Cell Differentiation
This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.
The Autonomic Nervous System - Sympathetic Division
Learners examine the function and wiring of the sympathetic nervous system.
The Formation of Ester Bonds in the Synthesis of Lipids
By Richard Wilkosz
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.
Fruit: Triumph of the Angiosperms
Learners read how fruits are classified according to their texture and according to how they developed from their floral anatomy.
The Plant Kingdom: An Introduction
Learners read about the mutations that occurred in plants for the successful transition from an aquatic to a terrestrial existence. The classification of plants is based on these adaptive structures.
By Jill Larson
In this animated object, students examine what happens when electrons share molecules.
Boiling Point of a Liquid
Learners examine how the boiling point increases with increasing pressure. An example from industry is given.
The Solid State
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
By Jonathan Harris
In this animated learning object, students examine the life cycles of a virus.
Identifying Compounds and Ions
Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.
Solubility of Ionic Compounds in Water
Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
