Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
The learner sorts a variety of foods based on personal preferences. Those personal choices are then classified by food group. The learner views the charts and reads information about the major food groups.
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.
Giving gifts is an important part of conducting business around the world. Learners read about the kinds of gifts that are welcomed in various cultures, and which are not. A quiz completes the activity.
In this learning activity you'll explore why the FTP protocol is often used to transfer data across the network and more importantly, why it should not be.
Users of this learning object evaluate the early online experiences of four hypothetical students and record the lessons that can be learned about what to do and what not to do to create effective online learning environments.
In this interactive learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.
In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
Learners read and listen to the pronunciation of hundreds of medical terms that are arranged in a "jukebox." The terms are listed alphabetically and according to the following categories: aerobic and anaerobic microorganisms, blood bank, coagulation, fungi microorganisms, hematology, protozoa, and urinalysis. This learning activity requires a computer that is equipped with speakers.
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
