Virus Particles: Structure and Function
By Kristine Snow
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
Virus Matching Exercises
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Urine Colony Counts (Screencast)
Learners watch a brief video clip. They then follow step-by-step instructions on how to do a urine colony count and examine the criteria for determining if a colony count represents an infection. A brief quiz completes the object.
The Regulation of Inducible Operons
By Richard Wilkosz
In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.
Test Your Knowledge of Miscellaneous Bacteria
By Marise Hussey
Learners match diseases with their portals of entry, causative agents, and associated vectors.
Parasite Matching Exercises
By Elizabeth Yoon
Learners match the names of parasitic organisms to the diseases they cause and the modes of transmission.
Microbial Flora in Body Sites
By Dawn Madl
In an interactive exercise, learners identify the human body sites that harbor a normal resident flora and the sites that are sterile.
Metabolic Pathways
In this screencast, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.
Mannitol Salt Agar
In this overview, students examine and identify mannitol positive and mannitol negative bacteria on mannitol salt agar.
Identification of Lactose Positive and Lactose Negative Bacteria on MacConkey Agar
By Kristine Snow, Marise Hussey
In this learning activity you'll observe the growth of gram negative organisms and determine if they're lactose positive or negative.
Host Defense
By Kristine Snow, Judy North
The student categorizes defense mechanisms as specific or non-specific.
Helpful Microbes in Your Daily Life (Screencast)
In this screencast, learners read how microbes in such items as yogurt, bread, insulin, and insect sprays improve our lives.
Gram Stain Procedure (Screencast)
Learners view video clips demonstrating Gram's staining procedure. Correctly stained slides are shown.
Fungal Disease Matching Exercises
Learners test their knowledge of fungal diseases by completing six exercises.
Eukaryotic Cells: Assembling the Cell
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.
Etiologic Agents of Bacterial Diseases
In this interactive object, learners match the bacterial etiologic agent to the disease it causes.
Endospores (Screencast)
Learners read about endospores and view video clips demonstrating spore staining procedures. Correctly stained slides are shown.
Correlation of Colony Morphology with Gram Stain Results
By Pat Griffin, Mary Beth Boettcher, Marise Hussey
Students choose the hypothesis and practice describing bacterial colonies using the steps of the scientific method.
Conjugation
In this learning activity you'll analyze the basic steps in conjugation and applies the effect to microbial characteristics.
Components of a Prokaryote (Screencast)
In this learning activity you'll assemble the components of a prokaryotic cell and match the names and functions with each structure.
Categories of Acquired Immunity
In this learning activity you'll evaluate the immune response including active, passive, natural, and artificial immunity.
Blood Agar and Hemolysis
Learners examine microscope images of blood agar and the various types of hemolysis that can be detected. A quiz completes the activity.
Audiology
By Donna Matusewic
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
Audiograms
Students read a description of audiograms. They review audiograms representing various degrees and types of hearing loss.
Antibiotic Susceptibility
In this learning activity you'll investigate the interaction of antimicrobial therapies and host defenses in eliminating an infection.
