In order to choose the subject of our experiment for Feria de Ciencias we must follow certain steps:

  • It follows the scientific method to design an experiment
  • It plans your project
  • The Report
  • The Presentation.
  • To choose a Subject

    The worse error consists of choosing a subject and to discover that we do not like! How to find the project of correct Fair of science

    Elije a branch of the science that interests to you, Biology, physics, chemistry etc. Remembers, your project can be a subcategory of the specific sports of a discipline. (because the medicine is part of Biology) What is happening around yours? If sights around, you can probably find something that is happening in your atmosphere. The local present events are often a good source of ideas for Fairs of science! It uses your library to find books for Fairs of science! Question to your older brother or twins, or your mother or father for some ideas…! It uses a web search engine, and investigua your idea in the Internet!

    Elije a project

    After you have chosen a project, it takes to end a certain investigation. It discovers the scientific science or principles behind your project. This I can imply doing the investigation in the library, interviews with people or being used the Internet!

    It develops a hypothesis

    A hypothesis is a declaration that tries to explain what you think that will happen when you prove the project. Cradle in the investigation is an educated conjecture that you do fact in your subject. Generally, the hypothesis will answer these questions: how, what, when, who, what, why or where. These are some of the characteristics of a good question on a project of fair of sciences:

    The question would have sufficiently to be interesting as reading it, and soon continuing during the next weeks.

    It must have at least three sources of intelligence written on the subject. It wishes to be able to be based on the experience of the others!

    The question must contain a factor (variable) that you can change in your experiment and at least a factor (variable) that you can measure.

    It designs an experimental procedure

    This one is the main part of the project of science fair. It is in the procedure that you decide how you will prove your hypothesis. It is necessary to describe them in sequence descendent. It is very important that when you design your experiment, your tests only the hypothesis, and not other things. These are called the uncontrolled variables. The uncontrolled variables are bad, and indicate generally that the procedure was not correct! Sometimes nevertheless, the best scientists cannot control all the variables, so you do not lose heart! Delay, what is a variable? The thing that you change on purpose to prove your hypothesis is the variable.

    It realises the procedure, and it registers your results. Your results are the things that happened in the experiment. You do not try to explain your results in this point, writes them in the form of a table of the data. These are your observations only!

    After you have picked up the results, it is hour to organize them and to analyze them of a certain way. Your data must be read easily, so its presentation is very important. It realises a table of the data, a graph or the letter to demonstrate his data. Also, the diagrams and the photographies can be absolutely useful in the data analysis. A PC can be a good tool when creating graphs. The programs of balance leaf can be used for the statistical analysis simple and to produce the graphs of your experimental datas.

    Finally, you must make draw conclusions. This one is the point of the project where sights your data and you decide if the hypothesis is true or false. If you can think about a way that this could be applied of life to a true situation, include it in your conclusions! For this you will have to resort to the Scientific Method

    It plans the Project

    The key of the success in any project consists of planning it. The projects of fairs of sciences take time. It is necessary to think how you will take to end the experiment, you pick up the results and beams his presentation. You can even have to make the experiment several times before securing more exact results. It tries to follow these general rules for the planning: It secures to a calendar or a notebook that you can use for the daily registry. It determines the goals and the terms for your goals. It follows the shown procedures above to help you. YOU DO NOT HOPE UP TO ONE WEEK BEFORE THE DATE OF DELIVERY! Beam a verification list to see that it has been finished and what this must be done… will help you more ahead while still alive also! Taking near two weeks additional to only finish your project… just in case! It verifies if the project works, before the date limit!

    The Report

    The report of fair of sciences is basically a copy written of everything what you do fact in your project. The report must sufficiently be clear and detailed so that any reader understands what you did, the results that you obtained and if the experimental evidence maintains your hypothesis. In addition, the BIBLIOGRAFIA.Gran must include your sources of intelligence that is to say, leaves from the report comes from the NEWSPAPER in which you wrote down all the details of your experiment. It organizes and it copies the information and it prepares tables and graphs that show clearly to your data and results. The report must be written in computer, with double-spaced and be bound in a portfolio. The requirements can vary according to the city or country, so it asks the masterful one on the rules of the fair in your region. In the report the following thing is due generally to include:

  • Title page - With the title of your centralized project. It chooses a short and descriptive title, that goes to the grain.
  • General analysis - It summarizes the most important points of your project. It indicates the intention, hypothesis, methods, results and conclusions that you obtained. It must be short and clear, and although it appears at the outset for benefit of the judges, is the latest in being written.
  • Recognitions - It recognizes the people who helped you.

    Table of contents

  • - Introduction Describes the problem of your investigation, indicates the intention, the hypothesis and briefly it mentions the methods that you will use. If it already has works related to the problem you can mention them. It tries to gain the attention of which to read your work. It explains why your investigation is important.
  • Objective - Here you must explain what is the reason so that you have decided to make this experiment and that results you wish to obtain.
  • Methodology - your experimental design, the material Describes in detail and equipment that you used, the procedure that you used.
  • Results - It presents the data that you found in clear form using tables and graphs.
  • Discussion of Results - Sample the most important results and indicates how they confirm (or they refute) your hypothesis. It presents the allowable errors in each measurement and the result.
  • Conclusion - In this section, it writes the results of your investigation. It mentions what you learned in your investigation. If your results supported your hypothesis indicates it thus. If the results did not support your hypothesis also it you must write. In addition you must include possible sources of very important error and, to make projections; it is good idea to suggest future investigations on the same subject.
  • Bibliography - Beam a listing of books and magazines that you used search information and that Internet sites helped you.
  • Appendices - Here additional information in the form of graphs, photos, drawings, ET is included
