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.
Body Sections and Divisions of the Abdominal Pelvic Cavity
In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.
Learners review Ohm's Law and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.
In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.
Users read about how course competencies relate to program outcomes. They listen to the testimonies of three students who describe learning activities that prepared them for the world of work. In a matching exercise, learners distinguish between course competencies and program outcomes.
In this scenario for working in teams, the learner reads profiles of six company employees and then chooses three people to work on a team on which the learner will also serve. The learner writes a justification of his/her decisions.
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
Learners are shown questions to ask themselves before they speak. They evaluate three responses according to the criteria presented. This activity has audio content.
Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.
Learners follow step-by-step instructions for finding the lowest common denominator for a group of algebraic fractions and then enter their answers to three problems. Immediate feedback is provided. This activity has audio content.
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.
Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
