Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

In this animated object, learners examine the hysteresis function of a sensor.

In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.

Another fun review game.

This game will help kindergarten, 1st, and 2nd grade students learn and review the difference between high and low sounds. Students will choose the number of players they want. When the game board comes up, click on the spin button. Read the question that appears. Answer the question. If answered correctly the bee will fly up higher toward the beehive. Have Fun!
