Visit a local synagogue (if there is one in your area). Arrange beforehand with the rabbi there, and ask him to explain to the class his understanding of the meaning of the Passover.
Think about what changes the students need to make their lives as a result of what they have learned. Try to make the lesson, then, as practical as possible. What have they learned that can impact how they live? How, then, can they make those changes in their own live?
