The Open Door Web Site (ODWS) is an online research tool designed for teachers and young scientists between the ages of 9 and 17. Authored entirely by science educators, the Open Doors Website features online textbooks, PowerPoint presentations, quizzes, study guides, and more. This website may especially be of interest to science instructors who teach in International Baccalaureate (IB) programs, as many of these materials align with IB goals and curriculum. While mostly centered on science curriculum, ODWS also includes resources related to the History of Science, Mathematics, and the French language. The website is well organized and easy to navigate, offering a useful study tool for students to research questions on their own or use as a resource while completing assignments outside of the classroom. As the Open Door team notes, ODWS is currently being updated to a new format; the transition will be complete by 2017. As a result, some pages may be presented in different formats.
