UC Irvine Evidence for An Earth Like Geochemistry of Exoplanets Report Paper


Question Description

This paper need 2 pages.

In this assignment, you will look for a report of some contemporary science in the news and attempt to understand and evaluate it according to the 6-step program for evaluating theoretical hypotheses described in Chapter 2 of, Understanding Scientific Reasoning.

You can use the sources (but not the examples) listed in the class Google Site > Science in the news (Links to an external site.), or use a source you prefer, so long as it is not merely a social media post. You may not use anything from Reddit or similar user-driven websites.

The report you find should be substantial, that is, it should give enough information about the episode that you have a reasonable chance of finding all the elements needed to understand and evaluate the episode. It doesn’t matter whether your episode leads to a judgment that the data agree with the evidence or not, or are inconclusive.

When you find a suitable episode, download a copy of the report — not just a URL, make a PDF — and also record the URL (or other bibliographic information) to cite in your assignment. Then, read the report of the episode and try to understand and evaluate it according to our program. You may find it valuable to dig deeper, looking up the original science that the report describes. You are not required to go to the scientific literature if there is enough detail to do an evaluation from your popular media source. I do not recommend going first to the scientific literature to find a study to evaluate. Then, write a 2 page report with your evaluation. (2 pages is a guideline, not a rule or limit, indicating roughly the scale of writing you should attempt. You can format your essay in any readable format -- changing font size or margin size to comply with the 2 page guideline is silly and won't fool anybody. )

Your assignment should include the following elements:

  1. A brief (1-2 paragraph) summary in your own words of the episode as described in the report you found.
  2. 5-6 paragraphs giving your evaluation of the episode. If your episode leads to the judgment that the data do not agree with predictions from a model, you will have 5 paragraphs. If the data agree with predictions, you will have 6 paragraphs.
  3. A diagram following the pattern of Figure 2.12 on page 36 of our textbook, but instead of using the labels for boxes such as “MODEL” and “DATA” and labels for arrows such as “observation/experiment” and “reasoning/calculation”, use brief descriptive labels about your episode, like the textbook does in Figures 2.10 and 2.11 on pages 32 and 33. Do not fill in the boxes with text that substitutes for the 6 paragraphs evaluating the episode.
  4. A bibliography citing the author(s), date of publication, title, and publishing source (with URL if you found your report on the internet). Your citation can follow any bibliography format you like, so long as these elements are included. The standard is that a reader should be able to know what your source is from reading the bibliography and be able to find the source themselves from your bibliography. A bibliography that only has titles, or authors is therefore not acceptable. A bibliography that only has URLs is also not acceptable.
  5. A copy of the report you used to write your evaluation.

Note that if you decide to submit a second time (because you needed to update your assignment), you will have to resubmit all of your PDFs, not just the one you changed.

For your convenience, I drew a template diagram and made it a fillable PDF. If you want to use this one rather than make your own, you can find it here: https://drive.google.com/open?id=1zPfeeyNEqgSfNsEU-1T50XgH2js_iNvf (Links to an external site.)

Your assignment will be graded for content and correctness. Since we obviously cannot read all the reports you find and include with your reports, we will rely on your summary in the first part of the assignment, though we may skim your report articles if we can’t make sense of your summary and perhaps to see that your evaluation is appropriate to the report.

(3 points) Coherence and clarity of writing in the summary.

(10 points — 2 for each understanding step, 2 for the 1-2 evaluation steps combined) Appropriateness and correctness of each of the 5-6 paragraphs to the report.
(2 points) Diagram follows the pattern of Figure 2.12 and is appropriately labeled.
(2 points) Bibliography is present and adequate.
(2 points) A copy of the report is included with your evaluation.
(1 point) Turning in something rather than nothing.

Please follow those all assignment, thanks

That PDF include all the Figures.

Appraising Scientific Reasoning



Appraising Scientific Reasoning: Evidence for an Earth-like Geochemistry of exoplanets
Scientific research carried out by researchers from University of California-Los Angeles
(UCLA) sought to study the geochemistry of planets from beyond our solar system. The study
aimed to show that there are many other Earth-like planets in the universe implying that the earth
is not as unique as it was initially thought to be. The research was carried out by a team of
astrophysicists and geochemists working together to combine their knowledge in their respective
fields. The study is based on studying the geochemistry of rocks that originate from other stars.
These rocks are primarily present in the earth as a result of asteroid strikes or fragments of rocks
coming from these stars landing on earth.
The researchers pioneered a method of determining the geochemistry of rocks that are
beyond the solar system. The primary bodies of interest were white dwarf stars, which are the
remnants of burned-out stars. Due to their strong gravitational pull, elements such as carbon and
oxygen get pulled into their interiors (Alexandra et al., 2019). This means that by observing...

I was on a very tight deadline but thanks to Studypool I was able to deliver my assignment on time.

The tutor was pretty knowledgeable, efficient and polite. Great service!

I did not know how to approach this question, Studypool helped me a lot.
