Police Officer Hiring: An Overview of the Selection Process
Learners read about the steps involved in the typical police officer hiring process. Each step is described. Learners then test their knowledge of the process in two drag-and-drop exercises.
Learners consider whether to lease or purchase equipment based on return on investment. This activity is geared toward operators of a dairy farm. Two pages contain audio.
Learners read the legal definition of sexual harassment and then evaluate two situations to determine if the behavior should be reported as possible sexual harassment.
In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.
Learners read about the purposes of balance sheets and income statements and then place accounts into these two financial statement categories in a drag-and-drop exercise.
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
