The initial COSMOS Learning Activities (demonstrators) were developed from teachers who are involved in the project, following specific teaching approaches. The Learning Activities are stored in zip or pdf format, depending the tools to used to package them. The Reload Learning Activity Viewer (available in the COSMOS Tool-Box) can be used to access the package of the structured educational resources of the scenario in zip format. Learning Activities in pdf format can be viewed with Acrobat Reader (available here).
