MD2 Discussion 2- Advanced investigations in Biology
eliable scientific information: We are flooded with information and have the ability to search thousands of sources for information about a specific topic using digital media. The results of our searches do not distinguish between reliable, research based information and opinion or secondary information. After completing the discussion activity, you will be able find original research on a given topic using web sources and the Excelsior library.
Participating in this activity will enable you to master module level outcome # 1 & 3.
For your discussion, consider a biological discipline of interest, and a related current problem and look for a recent research article. Describe the steps you took to find the article in your DQ response and summarize the research article (research question, method and result). Explain briefly what you learned in this exercise. Format your reference (research article) according to APA.
MD2 Discussion 2-The Seasons ( introduction to astronomy)
In this discussion assignment, each student will prepare a brief report (200-300 words) on a newly discovered exoplanet. Through the work of many astronomers around the world and ambitious new projects such as the Kepler mission, exoplanets are being discovered almost daily. In this assignment, you will have the opportunity to learn about some of the most recently discovered planets in other star systems and then share that knowledge with your classmates.
Before participating in the discussion:
1 View the video: Order from Chaos: The Birth of the Solar System [Video file][44 min 24 sec]
2 Watch the segment 15:00 – 30:30 minutes.
3 Read: 14.4
Let’s begin the discussion:
Start by visiting the Exoplanet Encyclopaedia, maintained by the Paris observatory, and clicking on the link to their ‘Catalog’ of exoplanets. As you can see, there are many hundreds of exoplanets that have been discovered so far, most within just the past decade!
Pick any planet in the catalog. Scroll down a bit before you choose a planet to minimize the chance of a classmate picking the same one.
For example, I went down the list and picked the planet HAT-P-29 b. When I clicked on its name, I was taken to a factsheet that has details such as orbital period, radius, etc., as well as information about the star it orbits. This factsheet also tells me how HAT-P-29 b was detected and when. Note the b at the end of the planet name means that it is a planet around the star HAT-P-29. In the ‘Related Publications’ section, I found the main scientific paper that announced the discovery of HAT-P-29 b. It is the primary source of much of the information listed on the factsheet and usually has many more details, such as the names of the researchers, where they work, details of the detection method used, etc.
Another potential source of information about your planet is the pre-print server named arXiv. Search by keyword and by title, using the name of the planet, to see if there are any papers on your planet published there. You will need the free Adobe Acrobat Reader to view any papers there as well as just about any digital version of a scientific paper, as they are usually in .pdf format. For full credit, you should explore at least one resource besides the Exoplanet Encyclopaedia. Be sure to cite references used.
A few words on arXiv.org are in order. Many of the papers there have only been submitted to professional research journals and so have not yet been published in the traditional sense. But they are written by research scientists and peer-reviewed somewhat by other scientists who read the papers. Some of the papers will never be published in the professional journals, for a variety of reasons. However, most new scientific results in the physical sciences are moving very quickly to this “pre-print archive” route and it is an important, free resource worth learning about. It allows non-scientists to read about cutting edge research without having to go to a research library or subscribe to expensive scientific journals.
Of course, many of you will not have the scientific background/knowledge to understand some of the content in the scientific papers you encounter in this activity. However, by reading just the abstract and the conclusions and/or discussion sections of the paper, a lot can be learned. It will be challenging but that is good thing!
This summary of terminology will be useful as you investigate the properties of your chosen exoplanet.
Your brief report (200-300 words) should include at least the following information about your chosen planet:
1 Name of exoplanet
2 How it was discovered
3 Its distance from Earth
4 The spectral type, mass, and age of the star it orbits
5 When it was discovered
6 Who discovered it
7 Any known information about the planet, such as its mass, size of its orbit, orbital period, etc.
