Overview – Extended essay in Science

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Must take the form of a research paper involving a hypothesis , model, or critical analysis.
  • Must demonstrate argumentation, comparison, or the extraction of relevant information or data.
  • A correctly formatted and executed lab
  • report could meet this criteria.
  • Must have an emphasis on a specific branch of science
    • Biology
    • Chemistry
    • Physics

Overview – Extended essay in Science

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • The purpose SHOULD NOT BE to inform the reader about a specific topic, nor should it be a summary of the latest discoveries in the specific branch of science.
  • You should be personally involved with the subject matter and not simply an informant.
  • Performing an experiment will help to ensure your involvement.

Research

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Different approaches to research CAN be taken.
  • Data – based: location and extraction of raw or processed data, not collected directly by the student which is then further defined and analyzed.
  • Experimental : design and implementation of an experiment, then personal collection and analysis of the data.
  • Theoretical (numerical): development of a quantitative or semi-quantitative description of some physical phenomenon, exercise of the model, predictions about its behavior and limitations.
  • Survey: formulation of a cohesive, ordered, analytical and supported (qualitative and quantitative) discussion of the topic.
  • Combination: some combination of the approaches listed above.
  • Question: Should students be encouraged to do an original piece of research, or should they analyze (in a new way) data that someone has collected (e.g. data obtained from a previous research study that perhaps has been published in a journal)? If they use existing primary data, I’m assuming that they will carry out an actual experiment?
  • Does it matter which approach I take?

First –hand Experiments

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Choose sensible and feasible experiments that do not require extensive lengths of time for the construction of the apparatus.
  • Highly sophisticated instruments are not required
  • It is recommended that the research for the essay be carried out under the direction of a school supervisor.
  • If, the research is carried out at a research institute or university under the guidance of an external supervisor then a cover letter outlining the nature of the supervision and the level of guidance provided.

First –Hand Experiments

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Choose a research question that can be treated effectively within the word limit and is not of a trivial nature.

Research topics

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Can be in the form of a question.
    • Example: Do wine bottles of different shapes behave as helmholtz resonators?
  • Can be presented as a statement or a hypothesis.
    • The objective is to establish the relationship between power and temperature of an incandescent lamp.

Physics

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Should have a basis in physical theory and emphasize the essential nature of the subject.
  • If an interdisciplinary topic is analyzed ONLY the Physics component will be scored.
  • Avoid topics that go beyond the boundaries of conventional science. For example, metaphysics or pseudo-science. Examples of this:

Physics – Choice of Topic

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • A well-focused, well-defined and realistic topic that allows for an in-depth analysis should be chosen.
    • Broad and complex survey topics, for example, black holes, gravity, time machines, etc.
      • Will not permit the student to discuss conflicting ideas and theories.
      • Do not provide an opportunity to work “with” the materials/concept in a laboratory setting.

Physics - May be unsuitable due to safety issues

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Carcinogenic substances
  • Radioactive materials
  • Lasers
  • Microwaves
  • UV light
  • Noise
  • Heavy equipment

Warnings: First – hand experiments Physics

  • Excerpts from: International Baccalaureate Organization 2007 Handbook
  • Aerodynamics and hydrodynamics are theoretical & experimentally demanding. A topic within these domains must be chosen and defined carefully.
  • Physics of sports can be a source of excellent topics, although the acquisition of sufficient valid data can sometimes be problematic. The relevant biomechanics can be overwhelming.
