Temperature Emissivity of Non-Blackbodies (Screencast)
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
The learner will understand how to measure a problem over time by using a common run chart to visualize the gap between past performance and future goals.
Using Blueprints to Troubleshoot a Defective Water Pump
In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
Learners examine how language can interfere with clear communication. They select examples of ambiguity, assuring expressions, doublespeak euphemisms, jargon, emotive content, false implications, meaningless comparisons, and vagueness. In an interactive exercise, learners identify ways to overcome these barriers.
In this interactive object, part 3 in a series, learners follow the steps of the “mathemagician” to examine four numerical curiosities: What’s Special About 1089, Perfect Squares: 1089 and 9801, The Mathematical Significance of 1776, and The Calculator Number Game. The learner will also study six number patterns and look at one remarkable table. Immediate feedback is provided.
Introduction to Safety in the Chemistry Lab (Video)
Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
In this learning activity, learners will reflect on the meaning and impact of stereotypes in both personal relationships and work environments. Identifying behaviors, attitudes, and feelings associated with stereotypes are addressed in this activity.
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.
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
