Astronomy as a playful tool for teaching physics: equation of state and white dwarf stars
Keywords:Teaching of physics, Interdiciplinarity, Equation of state, White dwarfs, Chandrasekhar limit
This interdisciplinary work proposes the use of astronomy as a ludic tool to teach Physics, hence, to arouse the curiosity of undergraduate and graduate students from the program of Exact Sciences and the Earth courses, providing enhance on the teaching-learning process in Statistical Mechanics classes. The main goal of the present study is to discuss white dwarf stars (WDS), which are the final stage of the evolution of a star like the Sun and up to 8 M⊙ , since those are an interesting object of study because of their compact nature, high density, and, also, because they are eliminated as a degenerated fermi gas. Having as motivation and interest in the improvement of the knowledge regarding these objects, we aim to obtain the relationship between the mass and the radius of the white dwarf stars, as well as to classify a sample of 5 white dwarfs required by the Sloan Digital Sky Survey (SDSS), according to the chemical element that is destined for the surface. At the end of this work, we conclude throughthe mass and radius ratio of white dwarf stars that the greater the mass of the star, the smaller its size, and that in equilibrium it must have a mass less than 1.44 M⊙. In addition, we show a experiment reports of this teaching innovative that used astronomy as ludic tool to teach Physics in the subject of statistical mechanics at undergraduate and master’s level.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
