Have Creationists advanced any particular Theories of Origin that they claim are falsifiable via the scientific method? This is an attempt at an on-topic and useful version of this question - any  edits or feedback to ensure that it meets both of those aims are welcome.

To clarify the key term in use:


  Falsifiability is the ability of a theory—a working framework for explaining and predicting natural phenomena—to be disproved by an experiment or observation. - Rationalwiki


In my opinion, an ideal answer will be structured as an overview of different forms of Creationism with brief descriptions of any relevant theories including references.
Reasons to Believe is an organization which presents arguments in favor of Old Earth Creation, and on their Who We Are page, founder Hugh Ross states:


  One of the approaches I've developed, with the help of my RTB colleagues, is a biblical creation model that is testable, falsifiable, and predictive.


Their web site offers an overview of their "falsifiable" creation model approach, which includes:


  Using a model approach supplies researchers with enough detail to assist in further study. It offers explanations for how, when, where, and why the phenomena (or system) occurs. It anticipates, or “predicts,” discoveries that could either verify or falsify the model's explanation(s). The best models also yield specific suggestions for how near-future research may help improve understanding of the systems or phenomena they attempt to explain.


One example (the first I found) of a theory which they claim is falsifiable can be found in this article:


  These morphologically indistinguishable, yet genetically distinct ecomorphs can be properly considered as one of the many fingerprints that the Creator has left on His creation. In fact, if a single Creator was responsible for life, one could anticipate seeing repeated examples of the same blueprint throughout the biological realm. One would expect that a single Creator would reuse successful designs over and over again.


Note that this is not an academic article, so it's targeted at lay people, and as such the terminology is rather imprecise for my taste. It also seems to me that their claims of falsifiability are somewhat subjective, so I simply present them here as evidence that Creationists do, indeed, claim to produce falsifiable theories.
