I think this STAIR is a wonderful resource for students. I liked that you elevated the vocabulary to reflect the "clay" lingo but also defined it more clearly in parentheses. I'm a nerd when it comes to fonts and appearance, and I loved the colors and various heading fonts you used throughout your presentation. Your STAIR also included a lot of useful information that was supported with images (great for visual learners!). Great job!
As far as the flow of the presentation goes, I had some difficulty with the quiz section, and I clicked on incorrect answers, yet it allowed me to continue with the presentation. I'd just suggest going back and making sure the arrows are linked to the desired slide. Also, there were a few text boxes that needed to be extended in order to have all the text on one line.
