The Group 4 Interdisciplinary Science Project Abstract: So Hot! (Lola Abduvaitova, Dongjin Jeong, Dasoum Kimm, DeWon Kim, Nina Labadi, Won Suk Lee, Raza Niaz, Gulnara Radjapova)
//The purpose of our group’s experiment was to find out how important the temperature is in making tea. We investigated the question from different perspectives.// //Our purpose, as physicists, was to investigate the impact of mass of a tea pot on the change in the temperature of green tea. We assumed, the greater the mass of the teapot, the greater the temperature change of tea in the pot would be. Ceramic pieces with different masses were put in a calorimeter, in which pre-boiled water and the calorimeter cup were in thermal equilibrium. The initial temperature and the final temperature of the water were recorded. Our hypothesis was valid. Uncertainties were discussed by comparing the heat lost by the water plus the cup and the heat absorbed by the ceramic pieces.// //As our topic revolves around the temperature, we, as chemists investigated the amount of antioxidants in green tea of different temperatures. Antioxidant is a reducing agent which prevents oxidation of other molecules by oxidizing itself. Oxidation is a chemical reaction involving the transfer of electrons from the reducing agent to the oxidizing agent. By adding oxidizing agents into green tea, we calculated the amount of antioxidants in green tea made in different temperatures. We used 0.01 mol dm –3 K 2 Cr 2 O 7 as the oxidizing agent. Tea made at higher temperature contained more antioxidants, possibly due to tea concentration.// //The biologists investigated the influence of the temperature of water, on the release of chemicals in green tea leaves. The impact to the human body’s pulse pressure and heart rate were observed. Other than our main independent variable, other variables such as the height, weight and gender of the individuals being used for experimentation were also considered. We assumed that the higher temperature would have a larger effect on the human body.//

Extended Essay Criterion for Abstract
An abstract not exceeding 300 words must be included with the essay submitted. It does not serve as an introduction, but presents an overview of the extended essay, and should, therefore, be written last. The inclusion of an abstract is intended to encourage students to examine closely the development of an argument within the extended essay and the pertinence of any conclusions that are reached. It is also designed to allow readers to understand quickly the contents of the extended essay. The minimum requirements for the abstract are for it to state clearly: The abstract should be typed or word processed on one side of a sheet of paper, and placed immediately after the title page.
 * the research question being investigated
 * the scope of the investigation
 * the conclusion(s) of the extended essay.

J: abstract
(Objective 5) The requirements for the abstract are for it to state clearly the research question that was investigated, how the investigation was undertaken and the conclusion(s) of the essay.
 * ~ Achievement level ||~ Descriptor ||
