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.
Building Core Abilities During Student Learning Through Formative and Summative Assessment
This learning object gives instructors an opportunity to review the definitions of formative and summative assessment and list examples of the evaluations they use. In a drag and drop exercise, they classify a variety of assessment tools as either formative or summative.
Conversion Between Mass and Moles of an Element (Screencast)
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 view examples of waste in an office environment and are asked to consider what they can do to eliminate or reduce waste in their own workplace.
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
In this animated object, learners read about the uses of nanotechnology. The sciences, engineering, electronics, and other disciplines converge in nanotechnology. Examples are given for applications in manufacturing, biomedicine, and environmental science. Concerns about possible environmental effects are discussed.
Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.
Goal Setting: Business, Personal, and Family Goals
In the first section of this activity, learners listen to an introduction explaining the importance of setting goals in all aspects of life. The remaining pages list examples of goals and procedures relating to a farming operation.
