Chemistry extended essay research questions

Extended essay in chemistry The following is an overview of the extended essay guidelines for chemistry IBO documents An extended essay in chemistry provides students with an opportunity to investigate a particular aspect of the materials of our environment.

Such extended essays must be characterized by a particular chemical emphasis within a more general set of research criteria. The outcome of the research should be a coherent and structured piece of writing that effectively addresses a particular issue or research question and arrives at a particular, and preferably personal, conclusion.

Choice of topic It is important that the extended essay has a clear chemical emphasis and is not more closely related to another subject. Chemistry is the science that deals with the composition, characterization and transformation of substances.

A chemistry extended essay should, therefore, incorporate chemical principles and theory, and emphasize the essential nature of chemistry, relating to the study of matter and of the changes it undergoes.

Although the same assessment criteria apply to all extended essays, for an extended essay submitted in chemistry the topic chosen must allow an approach that distinctly involves chemistry.

Where a topic might be approached from different viewpoints, the treatment of the material must be approached from a chemistry perspective. For example, an extended essay in an interdisciplinary area such as biochemistry will, if registered as a chemistry extended essay, be judged on its chemical content, not its biological content.

The scope of the topic and the research associated with it should enable all the criteria to be addressed.

A good topic is one where the single research question is sharply focused and can be treated effectively within the word limit.

Perhaps the most important factor is the depth of treatment that can be given to the topic by the student.

Broad or complex survey topics for example, investigations into health problems caused by water pollution, chemotherapy for cancer treatment or the use of spectroscopy in chemical analysis will not permit the student to discuss conflicting ideas and theories, nor to produce an in-depth personal analysis within the word limit.

IB Chemistry revision notes and syllabus

Some topics may be unsuitable for investigation because of safety issues. For example, experiments involving toxic or dangerous chemicals, carcinogenic substances or radioactive materials should be avoided unless adequate safety apparatus and qualified supervision are available.

Other topics may be unsuitable because the outcome is already well known and documented in standard textbooks, and the student may not be able to show any personal input. An example might be a study of the reactions of the alkali metals with water as this is already covered by the syllabus.

However, some care does need to be exercised in deciding whether a topic is suitable or not; for example, previously, the study of the allotropes of carbon might have been thought to be trivial but this would not be the case today.

Example essay titles The following examples of titles for chemistry extended essays are intended as guidance only.

The pairings illustrate that focused topics indicated by the first title should be encouraged rather than broad topics indicated by the second title. Moreover, it may help if the student further defines and refines the topic chosen for study in the form of a research question or statement.

Title The ratio of the gases evolved at the positive electrode during the electrolysis of common salt solution Research question Is there a relationship between the concentration of aqueous sodium chloride solution and the ratio of the amounts of oxygen and chlorine gas that are evolved at the positive electrode during electrolysis.

Title The caffeine content of a cup of tea Research question Does the time it takes to brew a cup of tea using a specific commercial brand of tea leaves significantly alter the amount of caffeine that is dissolved in the drink? Title Analysis of strawberry jellies by paper chromatography Research question The use of paper chromatography to determine whether strawberry jellies obtained from 24 different countries in 5 different continents all contain the same red dyes.

Treatment of the topic An extended essay in chemistry may be based on literature, theoretical models or experimental data. Whichever category or combination of categories is chosen, the student should ensure that sufficient data is available for evaluation and that the topic can be researched accurately using locally available resources.
