Slides Carnival is a website that offers dozens of Google Slides templates. Provided that you are signed into your Google Account, each template can be saved to your Google Drive account by simply clicking the "use this presentation template" button that appears below each template. Once you have saved the template you can modify the content to suit your needs. I've embedded an example one of the Slides Carnival templates below.
Applications for Education
Slides Carnival isn't going to change the way students present, but it does offer a nice alternative to seeing the same old templates over and over again.
