Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

Learners examine how the boiling point increases with increasing pressure. An example from industry is given.

In this animated object, learners examine how the purge pressure system is used to measure levels of material. A brief quiz completes the activity.

Learners examine phase diagrams that show the phases of solid, liquid, and gas as well as the triple point and critical point.

This animated guide presents an FAA map and aerial photos showing various areas of interest to student pilots enrolled in flight training at FVTC Aviation at Wittman Regional Airport in Oshkosh, WI. The airport is the site of the annual Experimental Aircraft Association's AirVenture Oshkosh. This object has sound.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.
