Facts and ideas about Nuclear Power

Nuclear Power Prevents More Deaths Than It Causes (Source).  However, 47 people officially died due to the Chernobyl (Ukraine) meltdown. New research argues that the death toll is actually 985,000. Why is there such a difference in the two numbers?  Additionally, no one has died due to radiation from the Fukushima (Japan) nuclear disaster...yet, but how many will that be? (Source)

One uranium fuel pellet creates as much energy as one ton of coal or 17,000 cubic feet of natural gas (Source).   However,  Every 18 to 24 months, a power plant must shut down to remove its spent uranium fuel, which has become radioactive waste (Source) and United States power plants produce 2,000 metric tons of radioactive waste every year (Source).

Solar panels convert 22% of their available energy into electrical power, compared to nuclear energy’s 90% (Source and Source).100 nuclear facilities in 31 states provide nearly 20 percent of all U.S. electricity (Source).  However, coal amounts for 45% of the electricity generated in the U.S. (Source) and clean coal technology now exists which makes it much safer for the environment (source). One of the leading ideas is called carbon capture- trapping CO2 and turning it into a solid, then burying it (source).  However, some argue that clean coal is a myth (source and  source).

Dyson vacuum engineering

The instruction manual for the Dyson vacuum cleaner can be found here.  Start at page 32.

When you finish, go to edheads.org and click "Choose an Activity!"  and "design a cell phone"


Notebook check and nuclear posters

The second marking period notebook checks will begin Monday, November 17th.  I will be checking pages 13-26, all of which can be printed out from the upper right hand corner of this website, click "class notebook".

Your nuclear waste posters are due Monday or Tuesday.  They can be handed in on any paper and the instructions can be found here.


Nuclear Power: Pros and Cons

After completing the domino chain reaction activity, Read some of the following articles about nuclear power:

http://tiki.oneworld.net/energy/energy7.html  (basics of nuclear power)

http://science.howstuffworks.com/nuclear-power.htm  (how nuclear power works)

http://online.wsj.com/articles/SB121432182593500119  (more advanced pro and con list)

Then, on page 26 in your notebook, create a T-chart like this one  with some of the pros and cons about using it.  The more you find now, the better off you will be for a future assignment.




After the quiz, fill out the protons/neutrons/electrons sheet.  Then, 
Complete a summary of This week in Science and This week in technology.
If you need another sheet, it can be found here.


25 biggest moments in Science

I will be away from October 10th through October 19th. During this time, you will complete the 25 biggest moments in science presentation project.

Here is the link to the Google Presentation template. Please make a copy of this file and create your own presentation.

When you finish that, complete a summary of This week in Science and This week in technology.
 Fill out the "This week in _____" sheets. If you need another sheet, it can be found here.
