Some IB Chemistry IA Start-Up Ideas How does the content of ascorbic acid in common acidic foods, like lemon juice, change when heated? Measuring the difference in pH between two acidic samples. Separating Bacillus species from Clostridium strains using a catalase test. Comparing the hardness of different water samples—such as ordinary tap water, purified water, or water from a nearby pond—using complexometric titration with ethylenediamine tetraacetic acid (EDTA). Building an electrolytic cell to measure how temperature variations affect the pace at which steel corrodes. Assessing the impact of adding ethanol to gasoline on its combustion enthalpy using a water calorimeter experiment. Assessing how heating affects the concentration of. IB Physics IA example: What effect does a squash ball's temperature have on how high it bounces back when dropped from rest onto a fixed surface from a fixed height?

How to write a good IB chemistry IA and extended essay: Students are reminded that they must adhere to the word count of 4000-words; exceeding this limit will result in penalties. No more than 4000 words will be read or taken into consideration by the examiner. This can jeopardize the EE's evaluation based on every criterion. Additionally, students must use a range of sources to create a reasoned argument (including claims and counterclaims) in order to reach a conclusion, and the essay must be their own original work—they cannot plagiarize or falsify their data. Students will be required to reflect both throughout and after the research process at the conclusion of the EE. The EE is not just a lengthier IA; it is also not an extended laboratory report. If students write their EEs addressing the IA criteria, they will perform poorly. Even though many students still conduct their own experiments to gather their primary data, an EE entails additional research. www.topclassibtutors.com
