In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
Basic Types of Dimensioning Used in Engineering Drawings
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
Basic Elements of Dimensions Used in Engineering Drawings
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Introduction to Records Management: Types of Records
In this interactive object, learners read an overview of records management and then classify records as "vital," "important," "useful," or "nonessential" in a drag-and-drop exercise.
Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.
Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
