Conjugation
By Kristine Snow
In this learning activity you'll analyze the basic steps in conjugation and applies the effect to microbial characteristics.
Metabolic Pathways
By Elizabeth Yoon
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.
Endospores (Screencast)
Learners read about endospores and view video clips demonstrating spore staining procedures. Correctly stained slides are shown.
Categories of Acquired Immunity
In this learning activity you'll evaluate the immune response including active, passive, natural, and artificial immunity.
Gram Stain Procedure (Screencast)
Learners view video clips demonstrating Gram's staining procedure. Correctly stained slides are shown.
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.
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.
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.
Host Defense
By Kristine Snow, Judy North
The student categorizes defense mechanisms as specific or non-specific.
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.
"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.
"I Want to Be Well" Case 3: Respiratory Pathogens
In this learning activity you'll make observations and formulate an evaluation including diagnosis and microorganism identification.
Antibiotic Susceptibility
In this learning activity you'll investigate the interaction of antimicrobial therapies and host defenses in eliminating an infection.
Virus Particles: Structure and Function
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
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.
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.
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.
Mannitol Salt Agar
In this overview, students examine and identify mannitol positive and mannitol negative bacteria on mannitol salt agar.
Audiograms
By Donna Matusewic
Students read a description of audiograms. They review audiograms representing various degrees and types of hearing loss.
Microbial Flora in Body Sites
In an interactive exercise, learners identify the human body sites that harbor a normal resident flora and the sites that are sterile.
The Regulation of Inducible Operons
By Richard Wilkosz
In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.
Acid-Fast Staining
Learners view video clips demonstrating acid-fast staining procedures. Correctly stained slides are shown. The learning object includes two matching exercises.
Etiologic Agents of Bacterial Diseases
In this interactive object, learners match the bacterial etiologic agent to the disease it causes.
"I Want to Be Well" Case 2: Bacterial Pathogens
In this interactive object, learners review the case of a patient with meningococcal meningitis.
