How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
Learners see and hear how motivation on the job can be compared to the use of a bicycle. They then write an explanation of how this theory can be applied to a situation in their own workplace.
Every speech starts with an outline. Knowing how to write one can make the difference between speech success and speech failure. In this module, we’ll explore what’s involved in creating an outline, demonstrate how to put one together, and give you examples you can use to create your own outline.
In this interactive lesson, learners read and hear instructions for sending an e-mail. Steps are given for composing an e-mail message and for sending it. Students have an opportunity to write their own messages. A quiz follows the instruction.
Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.
Brainstorming helps find new ideas to problems. Learn how you can use brainstorming to write a paper, give a speech, or work on a group project. In this video, you’ll explore what brainstorming is and how to use it.
