In this learning activity you'll explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.
Normally Open vs. Normally Closed Pressure Control Valves
In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.
Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.
Hematologic Cells and their Functions: Blood Cell Identification (Screencast)
This screencast will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.
In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.
