Description
- Read the article titled “Aging US Power Grid Blacks Out More Than Any Other Developed Nation” under the Smart Grid terms section of the Science Corner. You can also view the article at http://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 “smart grid”.
- Read the article titled “Earth's Inconstant Magnetic Field” under the Earth’s Magnetic Field terms section of the Science Corner. You can also view the article at http://www.nasa.gov/vision/earth/lookingatearth/29dec_magneticfield.html. Next, summarize the main reasons why the researchers stated that “our planet's magnetic field is in a constant state of change”. 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.
- 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.

US Power Grid
The national electric grid in the United States of America is not in a good state and this
diminishes its efficiency. It experiences more power outages than any other developed country
and some of these outages extend to more than an hour. It is estimated that these outages cost
businesses in America about 150 billion dollars yearly on top of the many other economic losses.
This is because of the aging infrastructure which is not helped by the fact that the demand for
electricity is increasing. The grid dates back to the World War II and technology from the 60’s
and 70’s.
There is talk to improve the grid to...
