The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
Learners identify their values in a drag-and-drop exercise and read about the importance of taking initiative to move from scapegoating to accepting personal responsibility.
Learners examine the formulas that are used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Continuous Cycling Tuning Method.
Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.
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.
In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.
Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
