The International Boiling Point Project is an online, collaborative project for students in grades 6–12 in which they investigate the impact of four factors (room temperature, elevation, volume of water and heating device) on the boiling point of water. A detailed procedure is provided for students in order to limit the number of variables involved, so students can make valid comparisons of the data submitted by classes from around the world. An overview of the experiment is provided here with an emphasis on the data-collection and analysis aspects of the project.
