The Q & A application is a forum-like application that allows Explainers to post and answer questions about selected topics in the museum, or about science, to other users of the application. The users posting questions and answers generate all of the content on the site. The Q & A is accessible via the handheld and through a Web browser.

This application was developed to contrast most handheld applications in museums and allow Explainers to share their breadth of knowledge about their learning in a peer-to-peer fashion. The application also created a repository of Explainer-generated content, experiences, and practices.
