Grouped Numerical Frequency Distributions - Definitions: Second in a Series
By Thomas Pomykalski
In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.
Simplifying and Multiplying Algebraic Fractions
By Jim Cihak
In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions so that they can then be multiplied. This activity has audio content.
By Terry Lark
In this learning activity you'll practice calculating an inverse variation problem.
Simplifying Square Roots
By Roy Peterson
In this learning activity you'll simplify square roots involving the product of a numeric and variable term.
Designing a Ladder Diagram
By Terry Bartelt, Terry Fleischman
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
The Induction Motor Slip
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
By Barbara Liang
Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.
