EWC Presenter. EWC Presenter is a free tool that makes it easy to create slideshows, banner graphics, and interactive infographics. Infographics created on EWC Presenter can have background music added to them. This is similar to what Glogster used to offer for free. I was tipped off to this option through this infographic about bullying that is embedded below. It's a nice example of what your students could do with EWC Presenter. The shortcoming of this infographic is that it doesn't include links to the sources of the statistics presented in it.
The video below offers directions for using EWC Presenter.
