Students become engaged learners through this unit that prepares students for studying ancient Greece and combines learning basic research skills with digital storytelling skills.  While researching about Greek gods, heroes and creatures, students learn how to find main ideas in sentences and paragraphs in books and Internet articles, which they then learn to record in short phrases on index cards divided by topic.  Working with a partner, students turn these short phrases into the script for their digital story that includes music and pictures.
