Red Blood Cells
By Barbara Liang
In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.
The Cell Cycle
In this animated object, learners examine the different phases of a cell's life.
Orthographic Projection #1
By Glenn Sokolowski
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Reading a Micrometer
By Sue Silverstein
In this learning activity you'll practice reading a micrometer.
Basic Types of Dimensioning Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
In this animated object, the learner examines 17 types of joint movement.
Brain Exercise: Visualization #1
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
Transport Processes Requiring ATP
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
Current Divider Rule (CDR)
By Patrick Hoppe
Students review the Current Divider Rule (CDR) and work practice problems.
Levels of Prevention
By Lucie Cutler
In this interactive object, learners identify a variety of prevention activities as primary, secondary, or tertiary.
The Stress Response
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
Resistor Color Code Practice
In this learning activity you'll build a resistor's color code based on the bands.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Biomolecules: The Carbohydrates (Video)
By Becky Polk-Pohlman
Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.
Power Law: The Relationship of Voltage, Current, and Watts
Learners examine three formulas than can be used to find dc power. Examples are given.
Regional Body Parts
By Gerald Heins
In this interactive object, learners identify a person's regional body parts.
Chain of Infection
By Diane Cozzi
In this interactive object, learners identify nursing actions that help to prevent the spread of infection.
The Axial Skeleton: The Skull and the Rib Cage
In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.
An Overview of Pulmonary and Systemic Circulation
By Wendy Dusek
In this animated and interactive object, learners examine how blood flows through the heart and lungs. A brief quiz completes the activity.
Construction of the Cell Membrane (Video)
In this video you'll study the structure of the cell membrane and construct it using the correct molecules.
Converting Between Gray and Binary Codes
By Terry Bartelt
Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.
The Neuromuscular Junction
In this animated object, learners examine the major events that occur at the neuromuscular junction.
Print Reading: An Alphabet of Lines in Print Reading
By Kelly Curran
In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.
Transfer Functions: The RC Low Pass Filter
Students read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
The MOD 10 Counter
The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.
