Our next unit is about electricity and electronics. Observe the following graph, Graph 1. Write at least five sentences for each of the following questions. Write in third person. Directly cite data and identify the graph (1). 1.) Which electricity source in the US has increased the greatest amount over the time period shown in the graph? 2.) Which of the sources listed below directly contribute to global warming? Provide evidence and explain using the Internet (MLA citation). 3.) Describe the overall trends from 1972 to 1985 regarding the US's sources of electricity. [|This graph can also be seen at this LINK.]

Here is an example statement: "Graph 1 shows that from 1960-1965 there was a steady increase in the use of coal as a source of electricity. It rose from roughly 0.2 trillion killwatthours to 0.5 kilowatthours.

Please read the paragraph below about energy use to create electricity from 1972-1985 in the US. Observe that the graph is referred to, there is an introductory statement, supporting statements are backed up with data, and that their is a concluding sentence. This would have been a well written paragraph for question 3 in our previous blog entry.

"As seen in Graph 1, there were four sources of electricity production in the US from 1972-1985. These sources were coal, petroleum/natural gas, nuclear electric power, and hydroelectric power. From 1972-1985, the US needed greater and greater production of electricity from these combined resources. This best example of this is that during these years, coal increased from 0.5 trillion kilowatthours to roughly 1.5 trillion kilowatthours. During this same time period hydroelectric sources remained approximately the same at 0.3 trillion kilowatthours. There was a slight increase in nuclear electric power sources from 0.1 trillion kilowatthours to 0.3 trillion kilowatthours during this same time period. Finally, petroleum and natural gas showed the greatest amount of fluctuation during this time period staying about the same from 1972-1980 at 0.4 trillion kilowatthours but then deceasing to 0.3 trillion kilowattthours by 1985. Thus, although greater and greater amounts of resources were needed to produce electricity during this time period, coal accounted for the greatest increase in use." - JT

//**Using the above paragraph as a model, describe the changes in electricity production sources from 2000-2005. Make sure that you reference the graph (Graph 1). Make sure all statements are backed up with data. Make sure you have an introductory sentence and a concluding sentence that provide an overall summary/statement.**//

Entry: It shows in paragragh one that beetween 2000-2005 about the sources of electricty production. Then you seem to know the alot about the kilowatthours

Here is an example statement: "Graph 1 shows that from 1960-1965 there was a steady increase in the use of coal as a source of electricity. It rose from roughly 0.2 trillion killwatthours to 0.5 kilowatt hours.

Entry: Coal is the most increased electricity force from 1950 to 2005. This most likely has too do with global warming and this force was most used in global warming. Global warming is when certain gases get used up they and the ozone layer makes a whole and makes the polar ice caps melt. The certain gases that are used up to make global warming are Greenhouse gases such carbon dioxide,methane, and water.

Comment 1: The blog entry is not long enough in content. There are some spelling mistakes, and the questions are not answered as asked. for instance, the greenhouse gases were not asked, but only the energy sources that produce them. The second sentence is sort of confusing to me, as is the 3rd. I like how you show the most increased energy source is coal. Grant C.

Comment 2: I agree with Grant that the blog entry is not long enough. I think some wording is wrong like instead of calling coal is an electricity force maybe you can use source. You answered basically question number two about global warming. Yes, there are some spelling errors. Maybe you can change some of the grammar in sentence two. Good job! I like how you discussed about coal! ~ Jennifer N.

Comment 3: "REFERENCE THE GRAPH Coal is the most increased electricity force from 1950 to 2005 PROVIDE DATA HERE. This most likely has too SP do with global warming and this force was most used in global warming. WHERE IS YOUR SUPPORT Global warming is when certain gases get used up they and the ozone layer makes a whole and makes the polar ice caps melt. The certain gases that are used up to make global warming are Greenhouse gases such carbon dioxide,methane, and water. WHAT ABOUT THE OTHER SOURCES OF CO2 THAT ARE LISTED AS SOURCES IN THIS GRAPH." -JT

This trimester we started by finishing up our chemistry unit by doing an acid/base experiment. After this, we started our electricity/electronics unit in which we first made basic series and parallel circuits with buzzers, speakers, motors, and lights. We applied ohm's law to these experiments. Following this, we started working on the Radioshack Electronics Kits where we made complex circuits that had a variety of functions- blinking LEDs, screeching speakers, analog to digital converters, etc. The technology we used this trimester included the pH probes that we connected to our computers to get the pH of household chemicals, using the wiki to create an class test review sheet, the Radioshack Electronic Kits, and creating collaborative lab reports in the wiki for our electronics unit (instead of a formal lab report).

//__In this blog prompt, please write a paragraph long entry (5-6 sentences with a intro and concluding sentence) that addresses what you enjoyed during this trimester and what you have learned. You can also comment on what you would like to improve upon for next trimester or what was difficult for you. Feel free to comment on our snakes- Peppermint and Diablo if you would like to as well as the technology that you enjoyed this trimester. Please check your spelling and grammar as this blog entry may appear in your end of trimester comment. You may want to write it in Microsoft Word to check the spelling, etc. and then copy it in the blog.__//

Entry: What I have enjoyed through the year is all the stuff we have done on our computers with the blog. We have done are wikispaces and podcasts. I have enjoyed the wikispaces because everyone can see your work and it feels so public. I also like that with the podcast and i enjoyed taping it feels good doing stuff because you feel like a real scientist. I also have enjoyed building the circuits they are fun and also make scientist and you feel accomplished when you make it work. I have enjoyed the snakes and playing with them.

Comment 1: Alex has been in many of my groups for projects. He has helped alot with getting tasks done and working on the blogs. Great job Alex. -Andy N
