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

In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.

Students view drawings of the emitter resistor bypass capacitor.

In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.

Learners practice revising poorly written directions by applying criteria for giving directions.

The schematic symbols of logic gates used in digital circuits are shown.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
