Prezi presentations are beautiful, modern, and a fantastic replacement for or addition to Powerpoints and other more standard presentation material in the classroom. The fluidity or "zooming" nature of these presentations appeal to students' sense of novelty, and keeps them engaged even when the topic might seem dull.
This Prezi covers the Qin Dynasty, explaining its emergence after the Warring States Period and focusing on the ways that Qin Shihuangdi was able to bring unity to his empire. I use this with my advanced 6th grade students and it works great, but it could be adapted for higher or lower grades too. Hope you enjoy!
