Element creation Research

Superheavy Element 114 Confirmed

For this project you should start by reading the article that discusses the man made creation of an element. Normally it takes the power of a star to create new elements, but we have figured out a way to do it.

Then write a paragraph that summarizes the article. Paragraphs should be at least three well constructed sentences.

By the creation of new elements we have expanded our understanding of the nature of the chemical world.

The final part is to find an article or web site about any other topic related to ways we have expanded our knowledge about chemistry or the periodic table and link to it. Finally write a paragraph summarizing the material in your article. Again, paragraphs should be at least three well constructed sentences.

Make sure you put your ID on your work. This project is due by midnight Sunday, 10/11. If you did not do the last project you are required to do this one. If you do both projects one will count for extra credit. If you have problems, email me at aphsbio at gmail.com.

Single molecule's stunning image

Atoms and molecules are extremely small, much smaller than can be seen in the best microscopes available.

For this project you should start by reading this article that discusses the first real image of a molecule. Then write a paragraph that summarized the article. Paragraphs should be at least three well constructed sentences. For this article, you should know that a carbon nanotube is carbon atoms linked together, like a piece of rolled up chicken wire.

Then you should find an article about any other topic related to ways to visualize atoms or molecules, or material about their size and/or shape and link to it. Finally write a paragraph summarizing the material in that article. Again, paragraphs should be at least three well constructed sentences.

Make sure you put your ID on your work. This project is due by midnight Sunday, 9/27. Remember, you are required to do either this project or the one that will come next. If you do both, one will count for extra credit. If you have problems, email me at aphsbio at gmail.com.
