In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
Concepts of Programming 8: Pseudocode Repetition Structures using For Statement
Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.
Concepts of Programming 9: Pseudocode Repetition Structures using While Statements
Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Adding Fractions With Unlike Denominators (Screencast)
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.
Op Amp Fundamentals: The Transresistance Amplifier
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
Learners play a game to review concepts connected with student assessment. The categories on the game board are "General Assessment," "Science Assessment," "Math Assessment," and "Famous Scientists."
The Mathematics of Buying: Putting It All Together
Learners tackle this interactive learning object after studying the mathematics of buying. This activity ties together the ideas of net cost, list price, trade discounts, cash discounts, net cost equivalent, and single discount equivalent, as well as the concepts of part, base, and rate.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
Learners follow the FMEA process to predict potential failures and to prevent them. This activity uses the example of getting to work to help participants comprehend the concepts and to apply them to their own work processes.
