Using iPad apps for science inquiry projects can provide students with engaging ways to research, write, and share information. Some key affordances of iPad apps include interactivity that allows students to both consume and produce knowledge, multimodality which combines different media types, and connectivity through hyperlinking. Effective apps support inquiry-based learning through engaging students in asking questions, gathering evidence, and developing arguments on an issue. Note-taking, annotation, blogging, and mapping apps can be used to support each step of the scientific process.
