SCI 110 WEEK 4 DISCUSSION Week 4 Discussion “Pressure, Temperature, Electricity, and Magnetism” Please respond to the following: â€¢ Read the article titled â€œAging US Power Grid Blacks Out More Than Any Other Developed Nationâ€ under the Smart Grid terms section of the Science Corner. You can also view the article athttp://www.ibtimes.com/aging-us-power-grid-blacks-out-more-any-other-developed-nation-1631086. Next, assess the efficiency of the current state of the national electric grid in the United States. Then, describe the key challenges in updating this grid to a so-called â€œsmart gridâ€. â€¢ Read the article titled â€œEarth’s Inconstant Magnetic Fieldâ€ under the Earthâ€™s Magnetic Field terms section of the Science Corner. You can also view the article athttp://www.nasa.gov/vision/earth/lookingatearth/29dec_magneticfield.html. Next, summarize the main reasons why the researchers stated that â€œour planet’s magnetic field is in a constant state of changeâ€. Then, discuss the overall manner in which a magnetic reversal might impact human activities on Earth. Include one (1) example of such impact to support your response. â€¢ Demonstrate an instance of static charge such as seen with examples #32 and 33 shown on page 209 of your textbook. Next, post a picture of your example then explain the method of charging you used as well as the charges displayed in each object.
